Rev. 1.01 MPP13-00 System User's Manual 1

1 Introduction

In this chapter This chapter introduce the main characteristics of MPP13-00 stepper driver covering these topics:

• MPP13-00 definition• External components• System diagram• How to use this manual• Warranty information

1.1 MPP13-00 Definition

The figure in the precedent page shows the block diagram of MPP13-00 driver.The MPP13-00 converts clock and direction inputs into motor winding currents to control a two-phase stepper motor.Main features include: high current to drive a wide range of motor types, microstep for high resolution and smoothoperation through, internal voltage to frequency conversion to drive the MPP13-00 with an analog input (from -10to +10 Vdc) instead the clock and the direction input.Additionally four different current waveforms are available to drive stepper motor giving different motor performances.Additionally, when the internal clock is used, independent deceleration and acceleration ramps are available.The output phase current of the MPP13-00 is dip-switch selectable from 1A to 8A (±1%).Driver supplies regulated phase currents for supply voltages between 110 and 250 Vdc. It is designed for use witha wide range of EVER's line stepping motors.

Note: The motor winding must be compatible with the output current of the driver.

Drive Bipolar chopper drive - it is an H bridge that regulates motor windings current in PWM (Pulse Width Modulation)features mode, at a switching frequency of 20 Khz . This electronically controlled regulation of the motor current allows a low

heat dissipation of the driver, low electric noise and improved current control during motor breaking.

Current waveform - dip-switches selectable between four type of waveform : sinusoidal with binary step type,traditional whit binary step type, sinusoidal waveform whit decimal step type and sinusoidal corrected waveform withbinary step type

Microstepping - selectable whit dip-switches: full, 1/2, 1/4, 1/8, 1/16, 1/32 and 1/64 for binary step type, and full,1/2, 1/5, 1/10, 1/25 and 1/50 for decimal step type

Protection circuitry - disables the driver in the following case: if a short circuit occurs on the motor outputs; if a shortcircuit occurs between motors outputs and ground, if overheating is reached on the IGBT power devices and if thesupply voltage exceeds the gived tolerance.The driver must be power cycled to clear choppers.

IGBT power device - they allow to the driver to work with high current and high voltage, allows good performancesin motor torque and speed.The driver switching frequency of approximately 20 kHz, eliminate acoustical noise often associated with choppers.

Signal interface connection - optical isolation provides for all the standard commands like: clock, direction, currentreduction, current enabling, etc. . Besides the standard commands are available other input commands, described inthe next chapters, to have best flexibility in the use of the driver. The use of optical isolation increases the options available for system grounding. Whit optical isolation, the external logical system that commanding the inputs of the driver is not directly connectedto the motor power supply ground. This allows the system ground point for these signals to be made external to theunit.

WARNING! ELECTRIC SHOCK RISK!The power supply cables, the motor output cables and in certain internal parts of the MPP13-00 driver are apotential source of severe electrical shock and may be lethal. Follow the safety guidelines to avoid shock.


To avoid possible personal injury whenever you are working with the MPP13-00 unit:

• Connect the MPP13-00 rack ground terminal to the main grounding terminal and not simply to a groundedmechanical part (see figure Page.35, 37).The earth impedance must conform to the requirements of local industrial safety regulations.

• Do not operate the driver without the motor case and the rack of the driver connected to earth ground.

• Do not make any connections to the internal circuitry. The input and output signals are the only safeconnection points.

• Always turn off power supply before making or removing connections from the unit.

Note : Before handling or making maintenance on the MPP13-00 drive, wait that all the LEDs on thefront panel are switched off.

• Be careful of the J6 motor terminals when disconnected from the motor. With the motor disconnected andpower applied to the drive, these terminals have high voltage present.

• Do not use the ENABLE input as a safety shutdown. Always remove power to the drive for a safetyshutdown.

• Be careful of the dissipator on the MPP13-00 drive. If you use the drive for heavy application, when youunplug the drive from the rack, the dissipator must be at high temperature.Before unplug the drive from the rack wait some minutes for the cooling of the dissipator.

• Do not introduce tools in the ventilation grid when the fan is functioning.

2.3 Selecting Other System Components

Selecting an The MPP13-00 driver requires as a minimum CLOCK and DIRECTION inputs.Indexer Select an indexer, PLC or other logical control that provides, as a minimum, these commands. A compatible indexer

will provide the capability to drive the input circuits shown in Section 2.5 . For most applications that operate at speedsabove 300 rpm, an indexer that can ramp the step frequency is required.

Selecting a The MPP13-00 is designed for use with the most part of EVER's line stepper motors. motor The motor winding current rating must be compatible with the set output current of the driver.

Refer to the Torque/Speed Curves in the "EVER's Motors Catalogue" or contact our seller or our distributor for sizingand motor compatibility assistance.

Selecting A single power supply is required to operate the MPP13-00 driver.power The power supply can vary from +110 to +250 Volts at a maximum current of 8 Amps. It does not have to be a supply regulated supply.

A +24 Vdc is needed to supply the cooling fan. This must be a regulated supply.

In multi-axis applications, it is mandatory to run each power connection from supply to drive and not daisy-chain thepower connections.

Note: The supply voltage cannot exceed 280 volts (minimum breakdown input voltage).

3 Powering up the MPP13-00 Driver

In this chapter This chapter explains how to power up the MPP13-00driver after installation. Topics covered are:

• Different operation modes.• Explanation of single inputs commands.• Setting up functions using dip-switches and jumper.• Testing the installation.

This section is intended to familiarize the MPP13-00 user with different operation modes and the hardware adjustmentsand settings required to power up and operate the MPP13-00 driver.

3.5 Operation Modes

Introduction In this section are explained six different way to use MPP13-00 driver.

IMPORTANT NOTEEach operation mode excludes the use of a kind of input or function.Depending on the type of operation mode, do not connect and disable inputs or function not used.

3.5.1 Optically isolated command signals whit External Clock

Definition This is the most common way to drive the MPP13-00 with standard input command signal.Supply the input section whit a voltage from +5 to +12 Vdc applied to pin V1 (J10.17).You need at least the CK1signal (clock) to speed the motor and the DIR signal (direction) to change the sense of motorrotation. Additionally you can supply the ENABLE signal to enable/disable the driver and RWC/BOOST to reduceor increase the output current.Input commands in this mode are active to the low level (zero logic).

CK1 = Clock input functionENABLE = Enable/Disable input functionDIR = Direction input functionRWC/BOOST = Reduction or Boost input functionS/F = Not used / Do not connectedANALOG = Not used / Do not connectedBUSY = Not used / Do not connectedEMERGENCY = Used if necessaryCK-OUT = Not used / Do not connected

Available Selection of the step type.Settings Selection of the current waveform.

Selection of the automatic reduction or driver disabling.Selection of the motor current value.

Benefits This mode is the most used, and it allows the user to use standard indexers or PLC.

3.5.2 Optically isolated command signals whit Internal Clock

Definition This mode is used when an external logical control (indexer) is not available or when only a minimum and a maximumspeed are needed to move the motor.Supply the input section whit a voltage from +5 to +12 Vdc applied to pin V1 (J10.17).


Regulate a minimum and a maximum frequency value of the internal clock signal (see Section 3.7 for frequencyregulation) corresponding to the minimum and the maximum speed of stepper motor to the selected step type.Set DIP1.6 = ON if you want a minimum frequency of 0 Hz.Connect the +12 pin (J10.25) to the ANALOG input (J10.12); set DIP1.8 = ON to enable internal clock signal.Using the CK1/START (J10.5) input command like Start/Stop function you can only to stop (no movement for themotor) or move the motor directly to the maximum speed.

Note : Using Start/Stop function you can't benefit of ramp function

Connecting CK1/START (J10.5) to the common ground of optically isolated input supply, you can use S/F(Slow/Fast) input (J10.7) to switch between minimum and maximum speed.Using S/F function you can benefit of ramp function. A ramp is necessary, using stepper motor, if you want to changefrom a speed to another if there is a lot of different between two values, otherwise the motor stall.You can regulate the slope of acceleration and deceleration ramp from 10 to 350 ms (see Section 3.7 for ramp sloperegulation).With the CK-OUT (J10.16) output the user can monitoring the internal clock frequency value.Input commands in this mode are active to the low level (zero logic).

IMPORTANT NOTEUsing MPP13-00 internally generated clock signal, the stepper motor movement is not so precise like using aclock generated by an external indexer or PLC. So you have to use micro-switch or sensor to check when themotor is really at the end of its movement. However this is less expensive than use an indexer or PLC.

Benefits This mode allows the user to make easy application whit stepper motors and no complex electronics to controlmovement.

3.5.3 CMOS command signals whit External Clock

Definition This is the most common way to drive the MPP13-00 with standard input command signal.You do not have to supply the input section. Connect the common ground of the external indexer or PLC to the GNDpin (J10.13).You need, at least, to supply the CK1signal (clock) to speed the motor and DIR signal (direction) to change the senseof motor rotation. Additionally you can supply the ENABLE signal to enable/disable the driver and RWC/BOOSTto reduce or increase the output current.Input commands in this mode are active to the low level (zero logic).

IMPORTANT NOTEConnect the common ground of external indexer or PLC outputs only to the GND pin (J10.13), not to the GNDon power supply connector.





Benefits This mode is the most used, and it allows the user to use standard indexers or PLC whit CMOS outputs.

3.5.4 CMOS command signals whit Internal Clock

Definition This mode is used when an external logical control (indexer) is not available or when only a minimum and a maximumspeed are needed to move the motor.You do not have to supply the input section. Connect the common ground of the external indexer or PLC to the GNDpin (J10.13).

Regulate a minimum and a maximum frequency value of the internal clock signal (see Section 3.7 for frequencyregulation) corresponding to the minimum and the maximum speed of stepper motor to the selected step type.Set DIP1.6 = ON if you want a minimum frequency of 0 Hz.Connect the +12 pin (J10.25) to the ANALOG input (J10.12); set DIP1.8 = ON to enable internal clock signal.Using the CK1/START (J10.5) input command like Start/Stop function you can only to stop (no movement for themotor) or move the motor directly to the maximum speed.

Note : Using Start/Stop function you can't benefit of ramp function

Connecting CK1/START (J10.9) to the GND pin (J10.13), you can use S/F (Slow/Fast) input (J10.11) to switchbetween minimum and maximum speed.Using S/F function, you can benefit of ramp function. A ramp is necessary, using stepper motor, if you want to changefrom a speed to another if there is a lot of different between two values, otherwise the motor stall.You can regulate the slope of acceleration and deceleration ramp from 10 to 350 ms (see Section 3.7 for ramp sloperegulation).With the CK-OUT (J10.16) output the user can monitoring the internal clock frequency value.Input commands in this mode are active to the low level (zero logic).





Selection of the automatic reduction or driver disabling.Selection of the motor current value. Regulation of minimum and maximum frequency of internal clock generator.Regulation of acceleration and deceleration ramps slope.

Benefits This mode allows the user to make easy application whit stepper motors and don't need complex electronics to controlmovement.

3.5.5 CMOS command signals whit Internal Clock and Analog input

Definition Use this mode to drive MPP13-00 on the ANALOG input (J10.12) with a variable voltage from 0 to +10 Vdc .In this way you can vary the speed of the motor whit an external voltage or simply by connecting a potentiometer tothe ANALOG input how is showing in the following figure:

Regulate a minimum and a maximum frequency value of the internal clock signal (see Section 3.7 for frequencyregulation) corresponding to the minimum and the maximum speed of stepper motor to the selected step type.Set DIP1.6 = ON if you want a minimum frequency of 0 Hz.Connect CK1/START (J10.9) to the GND pin (J10.13). Set DIP1.8 = ON to enable internal clock signal.Regulate the slope of acceleration and deceleration ramp (see Section 3.7 for ramp slope regulation).Changing the voltage value applied to ANALOG input you change the speed value in proportional mode.

The following figure show how the speed of stepper motor change at the variation of the applied voltage:

Using a voltage from -10 to +10 Vdc it is possible to change the motor speed and the direction at the same time bysimply change the polarity of the analog voltage.


If input voltage is regulated by an external logical control or PLC, when you want to change direction you have to waitthat internal clock signal is going down to the 0 Hz value before changing polarity (direction) of external voltage. You have to wait that deceleration phase of the motor if finished before change direction; otherwise the motor stall ifyou change direction at high speed. An output signal called BUSY (J10.24) is used to communicate to external indexerthat the internal clock signal is 0 Hz (motor stopped), and enable you to change polarity of the input voltage. BUSYsignal is normally closed to zero (GND) by an open collector transistor.The following figure show the right mode to drive MPP13-00 whit a bipolar voltage using ANALOG and BUSYsignals.

Note : BUSY output signal is given when the input analog voltage pass through +0.05Vdc or -0.05Vdc thresholdvoltage.This threshold voltage is the same for the "automatic disabling internal clock signal" (DIP1.6=ON).

Benefits This mode allows the user to make easy application whit stepper motors and don't need complex electronics to controlmovement.

3.5.6 CMOS or Optically Isolated signals whit Clock-UP and Clock-DOWN

Definition This mode is the same of 3.1.1 and 3.1.3 with the only difference that direction function is allowed changing the inputwhere the external clock is applied.Applying the external clock to CK1 input the direction of motor movement is the same like in 3.5.1 and 3.5.3 modes.Applying the external clock to CK2 input the direction of motor movement is reversing respect CK1.

Benefits This mode can be used if you need a different speed for each direction of motor.


3.6 Explanation and characteristics of single signals

CK1 Input clock signal. This input must be driven whit a voltage from +5 to +12 Vdc. It is active on the RISE Front and it is preferably tohave a duty-cycle of 50%. The frequency of CK1 signal is proportional to the motor speed, and each pulse of clock signal correspond to a stepof the motor.See Appendix A for electrical specifications about this input.

START Enable motion input signal. This input must be driven whit a voltage from +5 to +12 Vdc. Start command is active on the LOW state.It is used like start/stop function when the internal clock signal is used.See section for electrical specifications on this input.

DIR Direction input signal.This input must be driven whit a voltage from +5 to +12 Vdc. It must be given 15µs before the rise front of the clockpulse, and stay on the selected logic state for 15µs to be accepted. See Appendix A for electrical specifications about this input.

CK2 Input clock signal that give reversed direction of motor motion respect to CK1. It has the same characteristics of CK1clock signal. See Appendix A for electrical specifications about this input.

ENABLE Enable MPP13-00 power stage input signal. This input must be driven whit a voltage from +5 to +12 Vdc. By factory default (DIP1.7=ON) it is active on theHIGH state. When it is at the low state the MPP13-00 power stage is disable and the motor is stopped whit no motorcurrent. The function can be reversed setting DIP1.7 = OFF (See Section 3.7) .The enable/disable function is executed after 85µs that the command on the input is given.See Appendix A for electrical specifications about this input.

ATTENTIONDo not disable MPP13-00 power stage with ENABLE command input when motor is running.Is a good procedure to stop the motor in torque with a deceleration phase and giving a 0 Hz clock, and THEN(when the motor is locked) disable the MPP13-00 power stage whit the ENABLE command input.If you disabled MPP13-00 power stage (with ENABLE input command) when the stepper motor is running, themotor stop without current and torque. But when you re-enable the power stage, the motor start running from anundefined position creating a not stable situation at the start of the motion.Sometimes this undefined situation results in an opposite sense of motor rotation.

RWC Reduce Windings Current input signal. This input must be drived whit a voltage from +5 to +12 Vdc. This function is set by factory default. It is active onthe LOW state.This function reduces to the 40% the nominal current of the motor.See Appendix A for electrical specifications about this input.

Note : this function is not available if BOOST function is selected.

BOOST Booster input signal. This input must be driven whit a voltage from +5 to +12 Vdc. This function should be set connecting JUMP1between 1 and 2. This function is active on the LOW state.This function increases to the 120% the nominal current of the motor.See Appendix A for electrical specifications about this input.

Note : this function is not available if RWC function is selected.

Note : if you set a nominal current value near the maximum (8A), boost function can't increase the current valueover 8A. For example if you set a current of 7A, the boost function increases the current until 8 Amps andnot to 8.4 Amps.


S/F Slow/Fast speed input signal. This input must be driven whit a voltage from +5 to +12 Vdc. This input can be used only if internal clock signal isused. If LOW state signal is applied to this input, the internal clock signal is switched to the minimum value (speed).If HIGH state signal is applied to this input, the internal clock signal is switched to the maximum value (speed). See Appendix A for electrical specifications about this input.

EMERGENCY Emergency output signal. This is an open-collector output. During normal functioning this output is closed to the ground.If an emergency situation happens due to a protection intervention (over/under voltage, overloading, overheating, etc.)this output open. See Appendix A for electrical specifications about this output.

CK-OUT Internal clock monitoring output signal. For the CMOS output this is a +5 Vdc signal. For the optically isolated output this a +12 Vdc signal. Using theoptically isolated output you must give an external +12 Vdc regulated voltage (for example the same voltage givenon pin J10.17) to drive this output stage.See Appendix A for electrical specifications about this output.

BUSY Motor in the minimum speed state output signal. This is an open collector output . It is used only if MPP13-00 is driven by an external controlled voltage. When internalclock value and then the motor speed is zero or equal to the minimum set value: this output is open. If it is greater, theoutput is closed to ground (GND).See Appendix A for electrical specifications about this output.

3.7 Setting dip-switches, trimmers and jumper

Introduction Dip-switches DIP1 and DIP2, Jumper JUMP1, and trimmer RV1, RV2, RV3, RV4 and RV5 set the following:

• Step size.• Automatic current reduction and power stage disabling• Enable use of CK2 input whit reversed direction.• Reverse functionally of ENABLE input.• Enable use of internal clock signal.• Disable internal clock signal.• Waveform for motor current.• Motor current.• BOOST function.• Acceleration and deceleration ramps slope.• Minimum and maximum frequency value for internal clock signal.

Default settings As default, if the user does not require a specific setting-up for its MPP13-00, the driver is set-up in the followingmode:

! Step Type 1/8 ! Automatic current reduction ENABLED! Automatic current disabling DISABLED! Disabling internal clock

when ANALOG = 0v DISABLED! Reverse functionally of

the ENABLE input NORMAL! Enable use of internal Clock DISABLED! Enable use of CK2 (clock down) DISABLED! Waveform type Sinusoidal Binary Step! Phase Current 1 A! RWC/BOOST function selection RWC function! Acceleration Ramp slope 100 ms! Deceleration Ramp Slope 100 ms! Minimum Frequency of internal Clock 0 Hz! Maximum Frequency of internal Clock 20 Khz

See page 28 for default settings of DIP1 and DIP2 dip-switches.

CN5 During some regulation explained in the following paragraph, you need to connect your instruments to the CN5connector connector/test-point.

This connector is located on the front panel and it is a 4-pins male connector.The following picture show the pin-out of CN5 connector on the front view.


3.7.1 Step Size

Definition The step size sets the amount of rotation per input step. Seven step sizes are available using DIP1.1, DIP1.2 andDIP1.3 as shown. For all Ever stepper motors and all 1.8° step motors, step size can be converted to steps per rotationusing the following table:

Dip-switch DIP1 settings Binary Decimal

ON OFF OFF 1/64 Step 12800 Not used /

OFF OFF OFF Not used / Not used /

3.7.2 Automatic current reduction and power stage disabling

Definition Setting DIP1.4=ON you enables the driver to reduce the motor current to the 40% of its nominal value when the clockfrequency is 0 Hz or less than 2 Hz. In fact, 250 ms after there isn't a clock pulse: the driver reduces the motor current.When a clock signal greater than 2 Hz is applied: the motor current is restored to its original value.Setting DIP1.5=ON , 250 ms after there isn't a clock pulse: the MPP13-00 power stage is disabled and the motorcurrent is nulled. When a clock greater then 2 Hz is applied: the motor current is restored to its original value.

Note : The automatic power stage disabling function prevails on the automatic current reduction. If you set DIP1.5=ON and DIP1.4=ON, the current will never be automatically reduced.

3.7.3 Enable use of CK2 input whit reversed direction

Definition To use CK2 input like clock input with reversed direction of motor motion, you need to set DIP2.1=ON .Do not apply voltage to the ANALOG input.

3.7.4 Reverse functionally of ENABLE input

Definition By factory default DIP1.7=ON set ENABLE input as active on the HIGH level.To reverse the functionally of this input: set DIP1.7=OFF . This set ENABLE input to become active on the LOWlevel.

3.7.5 Enable use of internal clock signal

Definition To use the internal clock signal you have to set DIP1.8=ON.Do not use CK1 or CK2 as clock inputs but only like START and DIR inputs.Use S/F input to switch between the minimum (SLOW) and the maximum (FAST) speed regulated with RV4 andRV5. Use ANALOG input to change speed changing the applied voltage.For frequency regulations of internal clock signal refer to 3.7 section.


3.7.6 Disable internal clock signal

Definition Set DIP1.6=ON if you want disables the internal clock signal when the input voltage on the ANALOG input is zerovolt or when you switch to slow speed whit S/F ideas.For frequency regulations of internal clock signal refer to 3.7 section.

3.7.7 Waveform for motor current

Definition Setting DIP2.2 and DIP2.3 it is possible to choose a different waveform or type of step for the motor current.

Waveform Type DIP2.2 DIP2.3

Sinusoidal whit binary step type (Default)

OFF OFF

Traditional whit binary step type ON OFF

Sinusoidal with correction OFF ON

Sinusoidal whit decimal step type ON ON

Benefits Sinusoidal with binary step type: Whit this type of waveform the current form is similar to a sine curve. It allows a good torque performance until 1/64 of step (microstepping), but whit full step and half step the torqueperformances are not optimized.Traditional with binary step type: This is the traditional waveform used to drive stepper motor. It maximizes themotor power, and perform good torque to the full step and half step, but low torque performance using microstepping.Sinusoidal with correction and binary step type: It is similar to the sinusoidal waveform but it has been modifiedto reduce resonance problems typical of stepper motors.In fact, in particular speed situations, the stepper motor responds with a vibration and a noise due to the typicalconstruction technology of this motors.Sinusoidal with decimal step type: This type of waveform allows the same benefit of the first type of waveform, butperform a decimal step type (full step, half step, 1/5, 1/10, 1/25 and 1/50).

3.7.8 Motor current

Definition DIP2.4, DIP2.5, DIP2.6, DIP2.7 and DIP2.8 set the nominal value of motor current.You can vary the motor current from 1A to 8A (±1%) and obtain the values showing in the following table.

DIP2.4 DIP2.5 DIP2.6 DIP2.7 DIP2.8 Current (Ampère)

DIP2.4 DIP2.5 DIP2.6 DIP2.7 DIP2.8 Current (Ampère)

The above given values are intended for MPP13-00 driver supplied with VIN = 150Vdc. Changing the VIN, the valueof the motor current can vary ±2% of the above values.

IMPORTANT NOTEDo not set current values different from that EVER's Motors Catalogue give for your motor.High current values can cause motor overheating and sometimes motor damages.


3.7.9 BOOST function

Definition You can set the BOOST function simple by connecting JUMP1 between 1 and 2.When boost function is set you can't use the RWC input to reduce the motor current but only to activate the booster.In BOOST mode you can use the automatic current reduction when the motor is stopped.

3.7.10 Acceleration and deceleration ramps slope.

Definition Whit RV2 and RV1 trimmers on the front panel, it is possible to change the slope of acceleration and decelerationramp from 10 to 350 ms. RV3 regulates the offset of the ramp.The factory default value of ramp slope is 100ms, but you can order the MPP13-00 driver whit your pre-setted values.Otherwise, you can perform a self-regulation by means of an Oscilloscope, a voltmeter and a little screwdriver.

To self-regulate ramp slope follow this procedure:a Connect the oscilloscope probe between the pins GND and RAMP of CN5 connector on the front panel.b Set oscilloscope CH1: 2 v/div, 50 ms/div.c Connect your MPP13-00 drive in your final configuration (in this case should be DIP1.8=ON and START input

active). Apply to the ANALOG input the maximum voltage value that you want to use in your application.d Switch on the supply of MPP13-00 driver.e Switch S/F input to slow position.f Switch S/F input to fast position and control the slope of the acceleration ramp on the oscilloscope. g Rotate RV2 to increase or decrease the acceleration ramp slope.h Repeat procedure from the 'e' point until the right slope value is reached.m Switch S/F input to fast position.n Switch S/F input to slow position and control the slope of the deceleration ramp on the oscilloscope. o Rotate RV3 to increase or decrease the deceleration ramp slope.p Repeat procedure from the 'm' point until the right slope value is reached.q Apply to the RAMP pin of CN5 a voltmeter.q Applies to the ANALOG input: 0 Vdc . Switch S/F input to slow position.r Regulate RV3 to have 0Vdc (+0/-0.005 Vdc). In this way you re-calibrate the offset changed during the ramp slop

regulation.

Note : We suggest rechecking the maximum and the minimum frequency that you regulated after the ramp sloperegulation.

3.7.11 Minimum and maximum frequency value (PPS) for internal clock signal

Definition With RV4 and RV5 trimmers on the front panel, it is possible to change the minimum and the maximum frequencyvalue (PPS) of the internal clock signal.The factory default values of internal clock frequency are: Fmin = 50 Hz , Fmax = 20KHz. You can order MPP13-00driver whit your pre-setted values.Internal clock generator is sized to vary Fmin from 0 to 1KHz and Fmax from 12KHz to 40KHz (±5%) by meansof RV4 and RV5 .Otherwise, you can perform a self-regulation by means of a frequency meter and a little screwdriver.

To self-regulate internal clock frequency follow this procedure:a Connect the frequency meter probe between the pins GND and PPS of CN5 connector on the front panel.b Connect your MPP13-00 drive in your final configuration (in this case should be DIP1.8=ON and START input

to active). c Switch on the supply of MPP13-00 driver.d Applies to the ANALOG input the minimum voltage value that you want to use in your application.e Regulate RV4 until you see on the frequency meter screen the frequency value that you need (Fmin).f Applies to the ANALOG input the maximum voltage value that you want to use in your application.g Regulate RV5 until you see on the frequency meter screen the frequency value that you need (Fmax).h Repeat from d to g point until you reached the right values of frequency.

Note : To obtain higher frequency values from the internal clock generator, it is necessary to modify the internal circuitof MPP13-00. We suggest calling EVER support service to obtain specific explanation.

3.8 Testing the Installation

Background The following procedure verifies that the MPP13-00 is installed properly and that it was not damaged during shipment.

Procedure After installing the MPP13-00 as described in Chapter 2, test your installation as follows.

WarningPerform this initial power up with the motor shaft disconnected from the load. Improper wiring or undiscoveredshipping damage could result in undesirable motor motion. Be prepared to remove power if excessive motionoccurs.

Connections 1 Check all wiring and mounting to verify correct installation.test 2 With the power OFF, check that all settings are the same that you need for your application (see section 3.7 for

MPP13-00 settings). Enable the driver power stage (ENABLE input), disable START input (if you use internalclock signal), set high speed (S/F input). Do not give clock signal to the drive.

3 Switch on power and verify that only the green led on the front panel is light (POWER ON) and there are no redleds light.

Signal test 1 If you set only automatic current reduction (DIP1.4=ON), verify that the motor has holding torque by attemptingto rotate the motor shaft. The energised motor shaft is either immovable or is resistant to rotation.

2 If you use an external clock signal: give an input step command and verify that the motor moves.If you use internal clock signal: apply a voltage to ANALOG input and verify that the motor moves.

3 Reverse the direction signal (DIR) and verify that the direction of rotation change.

Getting help If you need further assistance with your installation, please contact EVER's service support.


4 Maintaining/Troubleshooting

In this chapter This chapter covers maintenance and troubleshooting of the MPP13-00 driver.

4.1 Maintaining the MPP13-00 Driver

Procedures The MPP13-00 driver need a minimum maintenance.Remove superficial dust and dirt from the unit using clean, dry, low-pressure air, above all in environments whit heavydust pollution.Have care to clean very often the ventilation grid and the fan to assure a good cooling.

4.2 Troubleshooting the MPP13-00 Driver

Introduction On the front panel of MPP13-00 driver there are four leds that display the good or bad functioning of the driver (referto the front panel figure page 41).

• POWER ON/OFF led : When it is lighted ON, it means that the driver is properly functioning.In normal conditions this is the only led lighted ON.

• OVER/UNDER V led : When it is lighted ON, it means that the drive is supplied whit a voltage out of theoperating range (minimum voltage value is 90Vdc and the maximum is 275Vdc) and the"voltage protection" disabled the driver power stage. In normal conditions this led is turned OFF.

• OVER CURRENT led : When it is lighted ON, it means that an overloading was reached on the motor and the"current protection" disabled the driver power stage. In normal conditions this led is turned OFF.

• OVER TEMP. led : When it is lighted ON, it means that an overheating on the power stage was reached(90°C is the minimum temperature value) and the "thermal protection" disabled the driverpower stage.In normal conditions this led is turned OFF.

The EMERGENCY output switch when a malfunction occurs on the driver and one of the red leds turn ON.

When MPP13-00 driver switch to the protection state, the power stage comes disabled and the motor loses the holdingtorque.Switch off the driver power supply and check for the problem before re-power the driver.

Use the troubleshooting table in the following page to diagnose and correct most problems. If you are unable to achievesatisfactory operation, contact EVER's Service Support.

IMPORTANT NOTE!

If you suspect that the MPP13-00 driver has been damaged, DO NOT simply replace it with another and applypower. Re-check general connections and power supply design and verifying that it meets all requirements.Improper supply design is the most common cause for damaged drivers.

Appendix B Power Supply Considerations

B.2 Power supply diagram

The figure below show our suggested power supply diagram to power one or more MPP13-00 drives.The transformer provides isolation from line and transform AC line voltage to a level that, when rectified, providesthe desired DC voltage for the driver. Diodes bridge DP1 and capacitor Cn provides to rectify the AC secondaryvoltage.Rn is a resistor used to quick discharge the capacitor when interruptor P1 switch off to disable the driver.All power supply components will be sized in the following sections.

Power supplydiagram

Warning

Power supply design must insure that VIN voltage never exceeds 250 volts under any operating conditions. These conditions include high line voltage, transformer regulation effects, voltage spiking due to currentswitching within the module and regeneration. Failure to do this can result in permanent damage to the MPP13-00

B.3 Line Transformer Selection

Primary Make sure that the transformer is guaranteed to operate at the highest line voltage combined with the lowest linevoltage and frequency that will ever be used to power your system. Failure to do so can result in saturation, large current increasesfrequency and winding failure.rating

Secondary High supply voltage values increases motor speed performances due the characteristics of H bridge of MPP13-00voltage power stage. But the power supply voltage cannot exceed 250 Vdc.


To calculate the maximum peak voltage after the diodes bridge: exclude any spiking due to the current switching ofthe driver and assume a 0.75 volts drop across each rectifier diode.The maximum peak voltage will be approximately:

Vp' = (1.414 * secondary rms voltage ) - 2*0.75

Assuming an increase of 10%for the line voltage, the peak voltage increases to :

Vp'' = (1.414 * secondary rms voltage * 1.1 ) - 2*0.75

Assuming an increase of 5% for secondary voltage when the load current is reduces from rated current to zero (forexample when the driver is disabled), the value of the peak voltage will be:

Vp = (1.414 * secondary rms voltage * 1.1 * 1.05 ) - 2*0.75

If the result exceeds the 250 volts of maximum operating voltage of the driver, you have to resize the transformerdecreasing the secondary nominal voltage.

Example If you select a 125 Vac secondary rms voltage, the maximum peak voltage will be:

Vp = (1.414 * 125 * 1.1 *1.05) -2*0.75 = 202.65 volts

This is a voltage included in the power supply voltage range.

Shielded To reduce the low power line noises is a good practice to use a shielded transformer.Transformer The following picture show the best way to shield a transformer and its grounding connections.

However, to use a shielded transformer, you have to shield at least the primary and secondary windings to obtain goodresult.


Transformer To make a quickly sizing of the transformer power, refer to the table in the following page where is showing the powerPower P of the transformer in VA relating to the power supply voltage and the motor current value. The power values given

in this table have to be considered like limit value resulting from the use of the motor at the top of the performancesand load. The value in the table is given for a single driver. If you want to supply more than one driver, you have to sum thepower needed for each driver.To self-calculate the power of the transformer you need to know:the maximum motor torque needed,the maximum speed of the motor.Refer to the following diagram to obtain, with a certain approximation, the power (in Watt) transferred to the load.

Example : Calculate the power of a transformer needed to supply an MPP13-00 that drive a motor whit a speed of 1500 rpm anda torque of 5 Nm.Choose a motor that supply the needed torque.Link with a line the point 1500 rpm (on the SPEED column) and the point 5 Nm (on the TORQUE column) until youintersect the POWER column. The intersection point corresponds to the power value of 750 Watts.To obtain the transformer power in VA, use this formula:

( 200 is the average lose power )

In the above example the resulting power will be:


B.4 Rectifier diode selection

Voltage The peak inverse voltage for the rectifier diodes of the bridge should be at least twice the rated secondary voltage.rating

Current The average current values related to the motor current are given in the table of the following table.rating

B.5 Capacitor Selection

The capacitor Cn (see figure Pag.42 ) should be sized in different ways according to the type of line.The capacitor value change if the line is a mono-phase or a three-phase.The table below gives a capacitance value for a single MPP13-00 as a function of the motor current setting, maximumpower supply voltage and type of line. These values are given assuming approximately 10% peak-to-peak ripplevoltage with a 50 Hz line.The value of I is the average current value absorbed by the driver on common application. AVGIn some application, where there are heavy work cycles, the current absorption must reach as a maximum the valueof the phase current set for the driver (the first column of the following tables).

(*) For rectifier diodes selection only


Working The capacitor's working voltage rating must exceed the maximum voltage under all line, load, and regen conditions.voltage Select a capacitor rated for at least 1.3 times the nominal supply voltage.

Example Suppose an MPP13-00 is operating at 150 volts and sets for 7A motor current.Assuming a 50 Hz mono-phase line, a 3300µF capacitor should be used. The capacitor should have a ripple currentrating of at least 7Amps and a working voltage of at least 1.3*150 = 195 Volts.

B.6 Fuse Selection

The external power supply Fn fuse (see figure page 42) should have the same value of the phase currents set for theMPP13-00 drive.

Note : Do not connect the fuse Fn between the driver and the capacitor Cn .If Fn breaking , the capacitor Cn should remain connected to the driver.

B.7 Discharge resistor

The discharge Rn resistor is used to quick discharge the condenser voltage when the power supply is switched off.Size the resistor to have a discharge time of about 10 sec, and assuming a discharge current equals to the nominalpower supply current.To calculate an approximate value for Rn applies these formulas:

Rn [Ohm] = 10 sec / Cn

P [Watt] = ( VIN / Rn )² * RnRn

Note : If it is possible, connect the Rn resistor in the way that it will be connected to the condensers terminal onlywhen the P1 interruptor is switched off. In this way the resistor Rn is not always under voltage and does notload the power supply.

Note : The discharge time must be conforming to the requirement of local industrial safety regulations.

Example If you use a power supply whit a nominal voltage of 150 Vdc and a capacitor of 10000µF, you should use:

Rn = 10 sec / Cn = 10 / 0.01 = 1000 Ohm

P = ( 150 / 1000 )² * 1000 = 22.5 W Rn

use a 1000 Ohm 25W

Appendix D Electromagnetic Compatibility (EMC)This driver was designed and tested to meet EMC requirements.

D.1 External Interferences Immunity

The result of MPP13-00 tests and design is a good immunity of drive to externally generated interferences.

ATTENTION !We secure this immunity with the drive plugged in EVER's rack and motherboard (see Appendix D for ordering

information).If MPP13-00 driver is used stand alone (without EVER's rack and motherboard), immunity of drive to externally generatedinterferences is not secured and must be tested with the drive plugged in the user's rack.

No special precautions are required to avoid external interferences beyond normal installation and cabling practices.We suggest to protecting the coils of DC-energised relay-switches, associated with MPP13-00 drive, with a diode to suppresselectrical transients that they can generate.

D.2 Drive Conducted Emissions

The MPP13-00 drive may be a source of interferences. The drive itself does not emit many interferences (irradiated emission), but the main way for propagation of interferences outof the driver is by conduction through its connections.These interferences are called "conducted emission".

To meet CE requirement on line emission, it is necessary to cut the conducted emission in the frequency range from 150KHzto 30Mhz.To avoid this emissions, read the information given in the following paragraphs.

D.2.1 Propagation Routes

The main propagation routes of conducted emission are the following connections (in order of emission level):

The Stepper Motor Cable : This cables carries the highest level of interferences and may disturb the nearby circuits.

The Power Supply Cable : This cables carries lower level of interferences than the motor cable, but it is the most importantroute for conducted emission into victim equipment.The length of the motor cable has influence on the supply cable conducted emission.

Grounding Connections : This connection carries the interferences returning from the motor frame and the driver grounding.This may cause problem if there are sensitive circuits that share these grounding connections.

D.2.2 Reduction of Drive Conducted Emissions

Following some precautions during the installation and cabling of MPP13-00 it is possible reduce the drive conductedemissions.

SEGREGATION : The first precaution is to segregate signal circuit or signal cable from noises cables.Do not run signal circuits or signal cable parallel to an unscreened motor cable or unfiltered supply cablewith a spacing less than 0.3m and over a distance exceeding 1m.If the above precaution is not applicable, separate signal circuits or signal cable from noises cables withgrounded metallic screen.


GROUNDING : Use wide copper conductors with low impedance to make grounding connection.Make the grounding connection the shortest possible.Do not share the grounding connection with other equipment, but connect the ground of the drive to the main lowimpedance grounding terminal.

Connect the grounding return of the motor cable only to the grounding terminal GRD of the rack, and not to other points.

The common line or GND of the input command signals must be grounded only at one point on the user's externalcontrol circuit, and no other points.

Maintain also the segregation between different grounding conductor.Example : a signal grounding conductor should not run close and parallel to a drive grounding conductor.

SUPPLY : A two-stage LC supply filter is needed to reduce line conducted emission and meet regulatory requirements.FILTER However a filter is recommended if there is a sensitive circuit installed on the same supply line, or if the motor cable

is longer than 50m and cause severe emission on the supply line.

The easiest way to meet CE requirement on the line emissions, is to use a commercial line filter.To choose a commercial filter you need to know the actual continuous RMS line current of the driver.Take as continuous RMS line current of the driver the motor current value you set.Add to this current the current of other loads supplied by the same line to get the minimum current rating of the filter.It is a good practice to oversize the filter.

The supply line filter should be insert between the line (380Vac, 220Vac,etc.) and the drive (including thetransformer), even if the transformer is close to the drive or in the same cabinet.If the drive is away from the transformer or in a different cabinet, we suggest to insert the supply line filter, on the ACline, between the transformer and the diodes bridge. In this case the rectifier circuit must be located closer to the drive.In both the cases the supply line filter must be installed physically close to the transformer or the diodes bridge withshort connection to the same.To avoid that noises on the supply line run into an electrical cabinet before reach the supply line filter, we suggest tophysically install the filter at the line input to the cabinet. The distance and the connections between the filter and thecircuit that have to be filtered must be the shortest possible to avoid interferences emission from the nearby circuitsin the same cabinet.The following picture show two different sites where a supply line filter can be located.


If the power supply of the external control logic is powered separately from the drive (using optocoupled inputs),you need to filter the control supply line in the same way described above with its own filter.

The same filter, IF it is mounted properly, contributes to reduce most of irradiate emission (from 30MHz to 80MHz)from the cabinet.For the line filter to attenuate drive noise to 30MHz to 80MHz, it is important that the filter case be grounded, withvery low impedance connection, to the drive rack. Mount the filter case near to the drive on the same mounting plate or common metal surface. The preferred mountingposition is on the outside wall of the cabinet near to the drive, with the line wires entering the cabinet near the filter.The line wiring between the filter and the driver must run along the common metal surface and away from the motorcables.

MOTOR : It Is a good practice to use a screened cable for motor connection. CABLE We suggest making your motor cable how is show in picture to page 6 .

Use a four cores screened cable for the motor supply with a grounding wire running parallel to the main motor cableand both closed into an insulating jacket.Connect the metal shield and the motor grounding only to the GRD grounding terminal of the MPP13-00 rack.

A screened cable may be more expensive than a conventional cable. For many applications it can be suitable to segregate the motor cable from other sensitive circuit or cables, leaving 1mspacing around the cable for every 10m run, or screen it with a metal shield. Avoid long parallel runs.

Another precaution to prevent drive from interfering with other equipment within a cabinet is to add a balun to themotor cable.Using a shielded motor cable up to 7m long, you need an ungapped ferrite toroid weighing more than 150 gr. , withan outside diameter of at least 50mm. and at least 13mm. in height.Place the balun on the motor cable near the output of the drive, and winding the hot wires of the cable at least 10/12turns through the toroid (do not wind the shield and the grounding cable on the toroid).Do not use too small ferrite toroids for a balun, because the current can saturate it and the filter performances will becompromised.Balun and ferrite toroids are available commercially from filter manufacturers.
