Drive software version

This product is supplied with the latest software version. If this drive is to be connected to an existing system or machine,all drive software versions should be verified to confirm the same functionality as drives of the same model alreadypresent. This may also apply to drives returned from a Control Techniques Service Centre or Repair Centre. If there isany doubt please contact the supplier of the product.

The software version of the drive can be checked by looking at Pr11.29 and Pr11.34. This takes the form of xx.yy.zzwhere Pr11.29 displays xx.yy and Pr11.34 displays zz. (e.g. for software version 01.01.00, Pr11.29 = 1.01 and Pr11.34displays 0).

Environmental statement

Control Techniques is committed to minimising the environmental impacts of its manufacturing operations and of itsproducts throughout their life cycle. To this end, we operate an Environmental Management System (EMS) which iscertified to the International Standard ISO 14001. Further information on the EMS, our Environmental Policy and otherrelevant information is available on request, or can be found at www.greendrives.com.

The electronic variable-speed drives manufactured by Control Techniques have the potential to save energy and(through increased machine/process efficiency) reduce raw material consumption and scrap throughout their longworking lifetime. In typical applications, these positive environmental effects far outweigh the negative impacts of productmanufacture and end-of-life disposal.

Nevertheless, when the products eventually reach the end of their useful life, they must not be discarded but shouldinstead be recycled by a specialist recycler of electronic equipment. Recyclers will find the products easy to dismantleinto their major component parts for efficient recycling. Many parts snap together and can be separated without the use

of tools, while other parts are secured with conventional fasteners. Virtually all parts of the product are suitable forrecycling.

Product packaging is of good quality and can be re-used. Large products are packed in wooden crates, while smallerproducts come in strong cardboard cartons which themselves have a high recycled fibre content. If not re-used, thesecontainers can be recycled. Polythene, used on the protective film and bags for wrapping product, can be recycled in thesame way. Control Techniques' packaging strategy prefers easily-recyclable materials of low environmental impact, andregular reviews identify opportunities for improvement.

When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.

REACH legislation

EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requiresthe supplier of an article to inform the recipient if it contains more than a specified proportion of any substance which is

considered by the European Chemicals Agency (ECHA) to be a Substance of Very High Concern (SVHC) and istherefore listed by them as a candidate for compulsory authorisation.

1 Safety Information

1.1 Warnings, Cautions and Notes

A Note contains information which helps to ensure correct operation ofthe product.

1.2 Electrical safety - general warning

The voltages used in the drive can cause severe electrical shock and/orburns, and could be lethal. Extreme care is necessary at all times whenworking with or adjacent to the drive.

Specific warnings are given at the relevant places in this User Guide.

1.3 System design and safety ofpersonnel

The drive is intended as a component for professional incorporation intocomplete equipment or a system. If installed incorrectly, the drive maypresent a safety hazard.

The drive uses high voltages and currents, carries a high level of storedelectrical energy, and is used to control equipment which can causeinjury.

Close attention is required to the electrical installation and the systemdesign to avoid hazards either in normal operation or in the event ofequipment malfunction. System design, installation, commissioning/start-up and maintenance must be carried out by personnel who have

the necessary training and experience. They must read this safetyinformation and this User Guide carefully.

The STOP and SAFE TORQUE OFF functions of the drive do not isolatedangerous voltages from the output of the drive or from any externaloption unit. The supply must be disconnected by an approved electricalisolation device before gaining access to the electrical connections.

With the sole exception of the SAFE TORQUE OFF function, none

of the drive functions must be used to ensure safety of personnel,

i.e. they must not be used for safety-related functions.

Careful consideration must be given to the functions of the drive whichmight result in a hazard, either through their intended behavior orthrough incorrect operation due to a fault. In any application where amalfunction of the drive or its control system could lead to or allowdamage, loss or injury, a risk analysis must be carried out, and where

necessary, further measures taken to reduce the risk - for example, anover-speed protection device in case of failure of the speed control, or afail-safe mechanical brake in case of loss of motor braking.

The SAFE TORQUE OFF function has been approved by BGIA asmeeting the requirements of the following standards, for the preventionof unexpected starting of the drive:

EN 61800-5-2:2007 SIL 3

EN ISO 13849-1:2006 PL e

EN 954-1:1997 Category 3

The SAFE TORQUE OFF function may be used in a safety-relatedapplication. The system designer is responsible for ensuring that thecomplete system is safe and designed correctly according to therelevant safety standards.

1.4 Environmental limits

Instructions in this User Guide regarding transport, storage, installationand use of the drive must be complied with, including the specifiedenvironmental limits. Drives must not be subjected to excessive physicalforce.

1.5 Access

Drive access must be restricted to authorized personnel only. Safetyregulations which apply at the place of use must be complied with.

1.6 Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fireenclosure must be provided. For further information, refer to section3.2.5 Fire protection on page 28.

1.7 Compliance with regulations

The installer is responsible for complying with all relevant regulations,such as national wiring regulations, accident prevention regulations andelectromagnetic compatibility (EMC) regulations. Particular attentionmust be given to the cross-sectional areas of conductors, the selectionof fuses or other protection, and protective ground (earth) connections.

This User Guide contains instruction for achieving compliance withspecific EMC standards.

Within the European Union, all machinery in which this product is usedmust comply with the following directives:

2006/42/EC Safety of machinery.2004/108/EC: Electromagnetic Compatibility.

1.8 Motor

Ensure the motor is installed in accordance with the manufacturersrecommendations. Ensure the motor shaft is not exposed.

Standard squirrel cage induction motors are designed for single speedoperation. If it is intended to use the capability of the drive to run a motorat speeds above its designed maximum, it is strongly recommended thatthe manufacturer is consulted first.

Low speeds may cause the motor to overheat because the cooling fan

becomes less effective. The motor should be installed with a protectionthermistor. If necessary, an electric forced vent fan should be used.

The values of the motor parameters set in the drive affect the protectionof the motor. The default values in the drive should not be relied upon.

It is essential that the correct value is entered in parameter0.46 motorrated current. This affects the thermal protection of the motor.

1.9 Mechanical brake control

The brake control functions are provided to allow well co-ordinatedoperation of an external brake with the drive. While both hardware andsoftware are designed to high standards of quality and robustness, theyare not intended for use as safety functions, i.e. where a fault or failurewould result in a risk of injury. In any application where the incorrectoperation of the brake release mechanism could result in injury,

independent protection devices of proven integrity must also beincorporated.

1.10 Adjusting parameters

Some parameters have a profound effect on the operation of the drive.They must not be altered without careful consideration of the impact onthe controlled system. Measures must be taken to prevent unwantedchanges due to error or tampering.

A Warning contains information which is essential foravoiding a safety hazard.

A Caution contains information which is necessary foravoiding a risk of damage to the product or other equipment.

2 Product Information

2.1 Ratings

The Unidrive SP is dual rated.The setting of the motor rated current determines which rating applies -Heavy Duty or Normal Duty.The two ratings are compatible with motors designed to IEC60034.The graph aside illustrates the difference between Normal Duty andHeavy Duty with respect to continuous current rating and short term

overload limits.

Only size 0 is Heavy Duty rated

Normal Duty Heavy Duty (default)

For applications which use Self ventilated (TENV/TEFC) inductionmotors and require a low overload capability, and full torque at lowspeeds is not required (e.g. fans, pumps).Self ventilated (TENV/TEFC) induction motors require increasedprotection against overload due to the reduced cooling effect of the fan

at low speed. To provide the correct level of protection the I2t softwareoperates at a level which is speed dependent. This is illustrated in thegraph below.

The speed at which the low speed protection takes effect can bechanged by the setting of Pr4.25. The protection starts when the motor

speed is below 15% of base speed when Pr4.25 = 0 (default) and below50% when Pr4.25 = 1.

For constant torque applications or applications which require a highoverload capability, or full torque is required at low speeds (e.g. winders,hoists).The thermal protection is set to protect force ventilated induction motorsand permanent magnet servo motors by default.

NIf the application uses a self ventilated (TENV/TEFC) induction motorand increased thermal protection is required for speeds below 50% basespeed, then this can be enabled by setting Pr4.25 = 1.

Operation of motor I2t protection (It.AC trip)

2.1.1 Typical short term overload limitsThe maximum percentage overload limit changes depending on the selected motor. Variations in motor rated current, motor power factor and motorleakage inductance all result in changes in the maximum possible overload. The exact value for a specific motor can be calculated using theequations detailed in Menu 4 in theAdvanced User Guide.

Typical values are shown in the table below for closed loop vector (VT) and open loop (OL) modes:

Table 2-5 Typical overload limits for size 0 to 5

Table 2-6 Typical overload limits for size 6

Generally the drive rated current is higher than the matching motor rated current allowing a higher level of overload than the default setting asillustrated by the example of a typical 4 pole motor.

The time allowed in the overload region is proportionally reduced at very low output frequency on some drive ratings.

The maximum overload level which can be attained is independent of the speed.

2.2 Model numberThe way in which the model numbers for the Unidrive SP range areformed is illustrated below.

2.3 Operating modes

The Unidrive SP is designed to operate in any of the following modes:

1. Open loop modeOpen loop vector modeFixed V/F mode (V/Hz)Quadratic V/F mode (V/Hz)

2. RFC mode3. Closed loop vector4. Servo5. Regen

2.3.1 Open loop modeThe drive applies power to the motor at frequencies varied by the user.

The motor speed is a result of the output frequency of the drive and slipdue to the mechanical load. The drive can improve the speed control ofthe motor by applying slip compensation. The performance at low speeddepends on whether V/F mode or open loop vector mode is selected.

For further details refer to section 8.1.1 Open loop motor controlonpage 137.

Open loop vector modeThe voltage applied to the motor is directly proportional to the frequencyexcept at low speed where the drive uses motor parameters to apply thecorrect voltage to keep the flux constant under varying load conditions.

Typically 100% torque is available down to 1Hz for a 50Hz motor.

Fixed V/F modeThe voltage applied to the motor is directly proportional to the frequencyexcept at low speed where a voltage boost is provided which is set by

the user. This mode can be used for multi-motor applications.Typically 100% torque is available down to 4Hz for a 50Hz motor.

Quadratic V/F modeThe voltage applied to the motor is directly proportional to the square ofthe frequency except at low speed where a voltage boost is providedwhich is set by the user. This mode can be used for running fan or pumpapplications with quadratic load characteristics or for multi-motorapplications. This mode is not suitable for applications requiring a highstarting torque.

2.3.2 RFC modeRotor flux control provides closed loop control without the need forposition feedback by using current, voltages and key motor parametersto estimate the motor speed.

It can eliminate instability traditionally associated with open loop controlsuch as operating large motors with light loads at low frequencies.

For further details, refer to section 8.1.2 RFC mode on page 139.

2.3.3 Closed loop vector modeFor use with induction motors with a feedback device installed.

The drive directly controls the speed of the motor using the feedbackdevice to ensure the rotor speed is exactly as demanded. Motor flux isaccurately controlled at all times to provide full torque all the way downto zero speed.

2.3.4 ServoFor use with permanent magnet brushless motors with a feedbackdevice installed.

The drive directly controls the speed of the motor using the feedbackdevice to ensure the rotor speed is exactly as demanded. Flux control isnot required because the motor is self excited by the permanentmagnets which form part of the rotor.

Absolute position information is required from the feedback device toensure the output voltage is accurately matched to the back EMF of themotor. Full torque is available all the way down to zero speed.

2.3.5 RegenFor use as a regenerative front end for four quadrant operation.

Regen operation allows bi-directional power flow to and from the AC

supply. This provides far greater efficiency levels in applications whichwould otherwise dissipate large amounts of energy in the form of heat ina braking resistor.

The harmonic content of the input current is negligible due to thesinusoidal nature of the waveform when compared to a conventionalbridge rectifier or SCR/thyristor front end.

See the Unidrive SP Regen Installation Guide for more informationabout operation in this mode.

3 Mechanical Installation

This chapter describes how to use all mechanical details to install thedrive. The drive is intended to be installed in an enclosure. Key featuresof this chapter include:

Through-hole mounting IP54 as standard or through-panel mounting Enclosure sizing and layout Solutions Module installing Terminal location and torque settings

3.1 Safety information

3.2 Planning the installation

The following considerations must be made when planning the installation:

3.2.1 AccessAccess must be restricted to authorized personnel only. Safetyregulations which apply at the place of use must be complied with.

The IP (Ingress Protection) rating of the drive is installation dependent.For further information, please refer to section 3.9 Enclosing standard

drive for high environmental protection on page 50.3.2.2 Environmental protectionThe drive must be protected from:

moisture, including dripping water or spraying water andcondensation. An anti-condensation heater may be required, whichmust be switched off when the drive is running.

contamination with electrically conductive material contamination with any form of dust which may restrict the fan, or

impair airflow over various components temperature beyond the specified operating and storage ranges corrosive gasses

During installation it is recommended that the vents on the drive arecovered to prevent debris (e.g. wire off-cuts) from entering the drive.

3.2.3 CoolingThe heat produced by the drive must be removed without its specifiedoperating temperature being exceeded. Note that a sealed enclosuregives much reduced cooling compared with a ventilated one, and mayneed to be larger and/or use internal air circulating fans.

For further information, refer to section 3.6.2 Enclosure sizingonpage 48.

3.2.4 Electrical safetyThe installation must be safe under normal and fault conditions.

Electrical installation instructions are given in Chapter 4 Electricalinstallation on page 67.

3.2.5 Fire protectionThe drive enclosure is not classified as a fire enclosure. A separate fireenclosure must be provided.

For installation in the USA, a NEMA 12 enclosure is suitable.

For installation outside the USA, the following (based on IEC 62109-1,standard for PV inverters) is recommended.

Enclosure can be metal and/or polymeric, polymer must meetrequirements which can be summarized for larger enclosures as usingmaterials meeting at least UL 94 class 5VB at the point of minimumthickness.

Air filter assemblies to be at least class V-2.

The location and size of the bottom shall cover the area shown in Figure3-1. Any part of the side which is within the area traced out by the 5angle is also considered to be part of the bottom of the fire enclosure.

Figure 3-1 Fire enclosure bottom layout

The bottom, including the part of the side considered to be part of thebottom, must be designed to prevent escape of burning material - eitherby having no openings or by having a baffle construction. This means

that openings for cables etc. must be sealed with materials meeting the5VB requirement, or else have a baffle above. See Figure 3-2 foracceptable baffle construction. This does not apply for mounting in anenclosed electrical operating area (restricted access) with concrete floor.

Figure 3-2 Fire enclosure baffle construction

Follow the instructionsThe mechanical and electrical installation instructions mustbe adhered to. Any questions or doubt should be referred tothe supplier of the equipment. It is the responsibility of theowner or user to ensure that the installation of the drive andany external option unit, and the way in which they areoperated and maintained, comply with the requirements ofthe Health and Safety at Work Act in the United Kingdom orapplicable legislation and regulations and codes of practice inthe country in which the equipment is used.

Competence of the installer

The drive must be installed by professional assemblers whoare familiar with the requirements for safety and EMC. Theassembler is responsible for ensuring that the end product orsystem complies with all the relevant laws in the countrywhere it is to be used.

Many of the drives in this product range weigh in excess of15kg (33lb). Use appropriate safeguards when lifting thesemodels.

A full list of drive weights can be found in section12.1.19 Weights on page 273.

Enclosure

The drive is intended to be mounted in an enclosure whichprevents access except by trained and authorizedpersonnel, and which prevents the ingress of contamination.It is designed for use in an environment classified aspollution degree 2 in accordance with IEC 60664-1. Thismeans that only dry, non-conducting contamination isacceptable.

3.2.6 Electromagnetic compatibilityVariable speed drives are powerful electronic circuits which can cause electromagnetic interference if not installed correctly with careful attention tothe layout of the wiring.

Some simple routine precautions can prevent disturbance to typical industrial control equipment.

If it is necessary to meet strict emission limits, or if it is known that electromagnetically sensitive equipment is located nearby, then full precautionsmust be observed. In-built into the drive, is an internal EMC filter, which reduces emissions under certain conditions. If these conditions are exceeded,then the use of an external EMC filter may be required at the drive inputs, which must be located very close to the drives. Space must be madeavailable for the filters and allowance made for carefully segregated wiring. Both levels of precautions are covered in section 4.11 EMC(Electromagnetic compatibility) on page 81.

3.2.7 Hazardous areasThe drive must not be located in a classified hazardous area unless it is installed in an approved enclosure and the installation is certified.

3.3 Terminal cover removal

3.3.1 Removing the terminal coversSize 0 is not installed with any terminal covers.Size 1 is installed with two terminal covers: Control and DC terminal covers.

Size 2 is installed with three terminal covers: Control, High current DC / Braking and low voltage DC terminal covers.

Size 3 is installed with four terminal covers: Control, High current DC / Braking, low voltage DC and AC terminal covers.

Size 4, 5 and 6 are installed with three terminal covers: Control, input and output terminal covers.

In order to provide access to the mounting holes when a size 1, 2 or 3 drive is through-panel mounted, the control terminal cover must be removed.For size 3 the high current DC / Braking and AC terminal covers must also be removed. Once the drive has been mounted, the terminal covers can bereplaced.

Isolation deviceThe AC supply must be disconnected from the drive using an approved isolation device before any cover is removed from the drive orbefore any servicing work is performed.

Stored chargeThe drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drivehas been energized, the AC supply must be isolated at least ten minutes before work may continue.

Normally, the capacitors are discharged by an internal resistor. Under certain, unusual fault conditions, it is possible that the capacitors

may fail to discharge, or be prevented from being discharged by a voltage applied to the output terminals. If the drive has failed in a mannerthat causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult Control Techniquesor their authorized distributor.
