PLDS880 servo-step motor driver PLDS880

2. Scope of Delivery: PLDS880 servo-step motor DSP driver.

3. General Provisions

PLDS880 is a DSP processor based digital driver of Servo-Step Motor (SSM) with possibilityof driver parameter PC adjustment via USB interface. Driver may work in servo mode,servo-step mode and common step motor driver mode without encoder. In servo modeSSM is controlled as fully functional servo motor with position and speed control. Thisallows obtaining motor maximum moment output and excluding step skip at overload.Driver is highly efficient, SSM rotation noise and vibration is significantly reduced.Driver is optimal choice for Purelogic R&D PL57/PL86 Series 2 phase bipolar servo-stepmotors. Operation with other 2 phase SSM for instance Leadshine is also possible.The PLDS880 driver may independently work using the built-in motion controller. It allowsnot to use an external PLC and reduce the cost of the final system.The motion controller allows to control the rotation of the SSM / SM with a given speed andacceleration, using logic signals supplied to the optically isolated inputs of STEP / DIR /ENABLE. In addition, a manual control mode for the SSM rotor position is provided usingan encoder (MPG - manual pulse generator).

Driver features:• driver PC adjustment via USB interface. USB interface is galvanic isolated from

driver;• driver may work in servo mode, servo-step mode and common step motor driver

mode without encoder;• multi-stepping technology is used. Any SSM step division within 1…512;• PI-regulator in SSM phase control current loop with automatic adjustment of the Kp

and Ki parameters, depending on the connected SSM and supply voltage;• automatic compensation of SSM torque loss when increasing speed, in operation

without an encoder. Performance increase up to 20%. Used in operating modewithout encoder;

• SSM winding SC, SSM misconnection module detection*;• STEP/DIR/ENABLE/ERROR module control signal optic isolation;• built-in motion controller that supports several operating modes: CW / CCW mode,

DIR / START / STOP mode, MPG mode;• SSM soft start. After energizing or ENABLE signal SSM winding current is increased

gradually. This excludes typical “impact” at SSM start.• AUTO-SLEEP mode, driver after 2 sec. of downtime (STEP signal unavailability)

automatically switches to SSM rotor complete/partial current hold mode to reduceSSM heating. Used in operating mode without encoder;

• SSM reverse EMF effect detection*;• heating protection (temperature sensor);• power supply voltage polarity reversal protection (driver start is failed);• integral SSM mid-frequency resonance compensator;• integral damper;• ERROR driver trouble signal opto-isolated output;• SSM connection easy-to-use dismountable terminals;• STEP frequency, alarm, driver power supply indication.

*the correct function operation depends on the operating conditions.

When the driver is turned on, after removing the ENABLE signal or after changing thedriver operating modes, the SSM rotor position is initialized. At this moment, the SSM rotorrotates in an arbitrary direction by an angle of no more than 1.8º. For successfulinitialization, the rotor must not be locked by the brake or the mechanical part of theequipment.

All driver connections and operation mode changes shall be made only with disabledpower supply source.Do not install power supply disconnector (circuit breaker) after power supply source (atdriver power supply line). Disconnector may be installed only at ~220V side power supplyunit input.Do not connect driver power supply in series. Only “star” type connection is allowed (eachdriver separate power supply line is connected to PSU.Do not connect the “-” of power supply to ground, housing, etc. Strictly observe the polarityof the power supply and control signals.

Attention! To configure the driver, you must use PLDConfigurator software.

6. Motion Controller

The driver has a built-in motion controller that supports several modes of operation. Themotion controller allows to control the rotation of the SSM / SM with a given speed andacceleration, using logic signals supplied to the optically isolated inputs of STEP / DIR /ENABLE. In addition, there is a mode for manual control of the rotor position using anencoder (MPG).The operation mode of the motion controller is selected by the Step_Gen_Mode parameter.The rotation speed is set by the Step_Gen_Vel parameter or the potentiometer R,depending on the Step_Gen_Vel_Src parameter. Acceleration / deceleration is set by theStep_Gen_Accel parameter.

1) Mode 0, Step_Gen_Mode = 0. The built-in motion controller is turned off, the driverworks in the standard STEP / DIR / ENABLE mode.2) Mode 1, DIR / START / STOP, Step_Gen_Mode = 1. SSM / SM rotates at a given speed andacceleration. When a logical "1" is applied to the DIR input, the rotation direction changes.When a logical "1" is applied to the STEP input, the rotation stops. When a logical “1” isapplied to the ENABLE input, the SSM / SM windings are deenergized.3) Mode 2, CW / CCW, Step_Gen_Mode = 2. When a logical “1” is applied to the DIR input,the SSM / SM rotates at a given speed and acceleration clockwise. When a logical “1” isapplied to the STEP input, the SSM / SM rotates at a given speed and accelerationcounterclockwise. If logical “1” is not applied to either of the STEP / DIR inputs, or isapplied directly to both STEP / DIR inputs, then rotation stops. When a logical “1” is appliedto the ENABLE input, the SSM / SM windings are deenergized.4) Mode 3, MPG, Step_Gen_Mode = 3. Mode for controlling the position of the SM motorrotor by the quadrature ABAB encoder (MPG). Only for stepper mode, parameterControl_Type = 2. 1 encoder pulse corresponds to the movement of the SM rotor by 1microstep set by the Microstep_Sel parameter.

7. Current and voltage selection

Driver power supply max. voltage selection depends upon used SSM and its requiredspeed. This SSM optimal power supply voltage is calculated by formula U= √ 32* (SSMphase inductance in mH), but max. 80V. PL57 type SSM recommended voltage is 45V. PL86type SSM recommended voltage is 70V.Power supply current shall be selected considering 50…70% of SSM winding specifiedoperating current. SSM operating current is set by corresponding value in configurationprogram (Work_Current and Work_Current_Max). If no STEP signal is available more than2 second driver is switched to sleep mode (AUTO-SLEEP mode) and reduces windingcurrent to the value of Hold_Current parameter.

8. Driver SSM connection

PLDS880 is a DSP processor based digital driver of Servo-Step Motor (SSM) with possibilityof driver parameter PC adjustment via USB interface.Purelogic R&D SSM is connected to driver according to Fig. 5 (terminals PH1.1(+A), PH1.2(-A) and PH2.1(+B), PH2.2(-B) and encoder connector). Encoder connector contactdesignation is also shown at Fig. 5. PLDS880 driver is connected acc. Fig. 4.Driver is protected against SSM winding misconnection between each other/to “+” ofpower supply and Short Circuit in encoder power supply circuit. Note that motor reverserotation is started at reversal of SSM PH1.x<>PH2.x phase connection and encoder A<>Bsignals (analog of DIR signal inversion).Connection of SSM phases and encoder signals is interrelated. If driver generates error 50(OverPosition) at initial startup exchange SSM PH1.x<>PH2 phases without changing ofencoder signal connection.Driver SSM conductor length shall be max. 10 meters. Longer conductors may result indriver operation failures.

It is highly recommended to arrange SSM wires in phase bundles: power +A and –A, +B and–B, encoder output A and A, B and B, put bundles in screened metal braids (power wires inone braid, encoder signal wires to other braid). SSM casing and braids shall be grounded.Do not arrange and lay encoder signal wires and SSM power conductor in one braid.

Description of adjustable parameters

Parameter Description

Work_Current Nominal operating current of SSM phases specified in technical certificate. Range is 0.1-0.8 (corresponds to 1A-8A). Used in servo-step mode and in operation without encoder.

Work_Current_Max The maximum operating current, peak current. Current increases to this valueautomatically at overloading in servo and servo-step mode. In operation without anencoder, the set excess current is used to compensate for the torque loss when increasingrotor speed. The larger parameter value brings the greater compensation. Compensationleads to additional SSM heating. If moment loss compensation is not necessary, you mustset this parameter equal to Work_Current. The range is 0.1-0.8 (corresponds to 1A-8 A).

Hold_Current SSM/SM idle current. Usually Hold_Current = ½ Work_Current.

Elec_Damp_K Step motor damping rate (resonance suppression). Used in operation without an encoder.The range is 0.0-10.0 (0.0 — is damping OFF, 10.0 — is maximum damping). Whenchoosing overestimated values, vibrations at low speeds and a shaft lock are possible.

Elec_Damp_Lim Step motor damping limit. Used in operation without an encoder. The range is 0.0-1.0.Typical value: 0.1. In most cases, no configuration required.

Speed_Error_Lim Setting the trigger threshold for the SSM rotor speed error. Used in all operating modes.The range of values is 0.0-1.0 (corresponds to 0-3000 rpm). Using a standard SSM withan angular step of 1.8 ° (200 steps per revolution) and setting the operating microstep1:20, the rotor speed of 3000 rpm will be obtained at a signal STEP frequency of 200 kHz.50 rpm (3000 rpm) * 200 * 20 = 200 kHz.

PI_I_Kp PI regulator proportional gain in step motor phase current regulating loop. Used in alloperating modes. Range is 1.0-127.0. Impacts SM acceleration, LF resonance.

PI_I_Ki PI regulator integral gain in step motor phase current regulating loop. Used in alloperating modes. Range is 0.0-10.0. Impacts SM acceleration, LF resonance.

PI_Pos_Kp PI regulator proportional gain in position regulating loop. Used in servo and servo-stepmodes. Range is 1.0-127.0.

PI_Pos_Ki PI regulator integral gain in position regulating loop. Used in servo and servo-stepmodes. Range is 0.0-10.0.

PI_Pos_Kd Position Derivative Gain. Derivative Gain provides damping by adjusting the output valueas a function of the rate of change of error. A low value provides very little damping,which may cause overshoot after a step change in position. Large values have slowerstep response but may allow higher Proportional Gain to be used without oscillation.Used in servo and servo-step modes. Range is 0.0-10.0.

Pos_Error_Lim The limit of the difference between commanded position and the actual measured posi-tion. When position following error exceeds the Pos_Error_Lim in the drive, the followingerror protection will be activated. Used in servo and servo-step modes. Range is 0.0-0.45(corresponds to 0-0.45 rotor revolution).

Kv_CC Velocity Proportional Gain. Kv_CC has similar effect as PI_I_Kp but it is in the velocityloop. Used in servo and servo-step modes. Allows additional reduction of position devia-tion. Range is 0.0-127.0.

Kvff_CC Velocity Integral Gain. It can be used to reduce the steady error of velocity when thevelocity is settled. Used in servo and servo-step modes. Allows additional reduction ofposition deviation. Range is 0.0-10.0.

Kvff_EA Lead Angle Gain. Used in servo and servo-step modes. Allows additional reduction ofposition deviation. Range is 0.0-10.0. In most cases, no configuration required.

Step_Gen_Accel SSM/SM acceleration/deceleration when motion controller ON. Range is 0.025-127.0, di-mension: 4*revolution/sec^2.

Step_Gen_Vel SSM/SM rotor speed when motion controller ON. Range is 0.0-1.0 (corresponds to 0-3000 rev/min).

Driver_ID Driver identification which is assigned by User. Used in all operating modes. Range is 0 –10000.

Control_Type Parameter selecting step motor control mode:0 – servo mode STEP/DIR/ENABLE;1 – step-servo mode STEP/DIR/ENABLE; 2 - normal mode without feedback STEP/DIR/ENABLE.

Microstep_Sel SM step division ratio. Used in all operating modes. Range: 1-512. The driver supportsMultiStepping technology. Even with a small step division, for example 1: 2, the driversmoothly "steps" with a microstep 1: 512.The accuracy of the SSM is determined only by the encoder resolution (ppr). Therefore, inservo and servo-step mode the microstep is an artificial value. In the operation modewithout an encoder, the microstep standardly divides the physical step of the SSM, in-creasing / decreasing the positioning accuracy.Driver works with SSM with an 1000 points encoder, which corresponds to a resolution of4000 pul / rev. A standard SSM with an angular step of 1.8 ° makes 200 steps perrevolution. This corresponds to 4000/200 = 20 equivalent microsteps.Therefore, it does not make sense to increase accuracy by setting the microstep above20. It is permissible to increase the microstep by more than 20 when using electronicgear to pair SSM with non-standard transmission. A microstep of less than 20 ispermissible, but this will lead to a loss of accuracy.

Step_Gen_Mode Parameter selecting motion controller operation mode:

0 – motion controller OFF;1 – mode 1, DIR/START/STOP; 2 – mode 2, CW/CCW; 3 – mode 3, MPG.

Step_Gen_Vel_Src Parameter selecting speed value source for motion controller:0 – speed value is set by Step_Gen_Vel parameter;1 – speed value is set by potentiometer R in the range 750 ... 0 ... 750 rpm; 2 – speed value is set by potentiometer R in the range 0...1500 rpm.

Driver_Enb Parameter controlling driver ON/OFF. “1” is driver ON. “0” is driver OFF.

Auto_Sleep_Enb Parameter controlling step motor current reduction circuit ON/OFF at idle time. “1” isON. “0” is OFF. Used in servo-step mode and in operation without an encoder.

Param_Ident_Enb The parameter controls the ON / OFF of module for automatic determination of the SSMparameters and calculation of PI_I_Kp / PI_I_Ki PI PI coefficients in the SSM currentcontrol loop. Range of value: «1» - module ON, «0» - module OFF.The process of determining the SSM parameters occurs when the driver is turned on,takes a time of ~ 0.5 s and can be accompanied by a slight change in the position of therotor or click.If you select driver download from standard profiles, parameter definition is enabled.If this is not acceptable for the current application, you must:1) Configure the necessary driver settings.2) Disable automatic parameter detection.3) Save current parameters to Bank 0.4) Set the switches SW1, SW2, SW3 to load the profile from "Bank 0".Thus, the driver will load faster, without changing the position of the rotor and withcorrectly configured parameters.Please note that:1) Parameters determination has an error that minimally affects the driver operation.2) When heating the SSM, the resistance R of the windings significantly changes (up to30%), which leads to a change in the parameters PI_I_Kp / PI_I_Ki. Therefore, for optimaldriver operation, it is recommended to save the parameters of the heated SSM.3) PI_I_Kp / PI_I_Ki are related to driver voltage. Therefore, the parameters will bedifferent for the same SSM at different supply voltages. For optimal driver operation, it isrecommended to save the SSM parameters for the current operating voltage.

PI_Pos_Kp, PI_Pos_Ki, PI_SPEED_Kp, PI_SPEED_Ki, QEP_PPR parameters are not usedin operational modes without encoder.
