1 Advanced user GuideCommander SKAC variable speed drive for 3 phase induction motors from to 110kW, to 150hpPart Number: 0472-0001-09 Issue: 9 InformationThe manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect installation or adjustment of the optional operating parameters of the equipment or from mismatching the variable speed drive with the contents of this Guide are believed to be correct at the time of printing. In the interests of a commitment to a policy of continuous development and improvement, the manufacturer reserves the right to change the specification of the product or its performance, or the contents of the Guide , without rights reserved. No parts of this Guide may be reproduced or transmitted in any form or by any means, electrical or mechanical including photocopying, recording or by an information storage or retrieval system, without permission in writing from the software versionThis product is supplied with the latest software version.

2 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 already present. This may also apply to drives returned from a Control Techniques Service Centre or Repair Centre. If there is any doubt please contact the supplier of the software version of the drive can be checked by looking at Pr and Pr This takes the form of where Pr displays and Pr displays zz. ( for software version , Pr = and Pr displays 0).Environmental statementControl Techniques is committed to minimising the environmental impacts of its manufacturing operations and of its products throughout their life cycle. To this end, we operate an Environmental Management System (EMS) which is certified to the International Standard ISO 14001. Further information on the EMS, our Environmental Policy and other relevant information is available on request, or can be found at 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 long working lifetime.

3 In typical applications, these positive environmental effects far outweigh the negative impacts of product manufacture and end-of-life , when the products eventually reach the end of their useful life, they must not be discarded but should instead be recycled by a specialist recycler of electronic equipment. Recyclers will find the products easy to dismantle into their major component parts for efficient recycling. Many parts snap together and can be separated without the use of tools, whilst other parts are secured with conventional fasteners. Virtually all parts of the product are suitable for packaging is of good quality and can be re-used. Large products are packed in wooden crates, while smaller products come in strong cardboard cartons which themselves have a high recycled fibre content. If not re-used, these containers can be recycled. Polythene, used on the protective film and bags for wrapping product, can be recycled in the same way.

4 Control Techniques' packaging strategy prefers easily-recyclable materials of low environmental impact, and regular reviews identify opportunities for preparing to recycle or dispose of any product or packaging, please observe local legislation and best legislationEC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requires the 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 is therefore listed by them as a candidate for compulsory current information on how this requirement applies in relation to specific Control Techniques products, please approach your usual contact in the first instance.

7 The drive uses an open loop vector control strategy to maintain almost constant flux in the motor by dynamically adjusting the motor voltage according to the load on the AC supply is rectified through a bridge rectifier and then smoothed across high voltage capacitors to produce a constant voltage DC bus. The DC bus is then switched through an IGBT bridge to produce AC at a variable voltage and a variable frequency. This AC output is synthesized by a pattern of on-off switching applied to the gates of the IGBTs. This method of switching the IGBTs is known as Pulse Width Modulation (PWM).Software structureFor the majority of applications, the Commander SK's keypad and display can be used to set up the drive through 'menu 0'. Menu 0 is structured to give an extreme ease of set-up for a simple drive but with the flexibility for more demanding applications. See the Commander SK Getting Started Guide for applications that require extra functionality, the Advanced parameters from menu 1 through to menu 21 can be used.

8 These Advanced parameters can be programmed and adjusted using the drives keypad and display or by using CTSoft. Also, the optional LED or LCD keypads can be used to monitor and adjust further enhance the functionality of the Commander SK, a number of Solutions Modules, SmartStick copying option and a LogicStick PLC ladder logic option are also available.

9 Normally Pr (not Pr ) is set to 1000 and a reset command is given to initiate a parameter save. This can be achieved on the drive by setting Pr 71 to , then setting Pr 61 to 1000 and a reset command to activate a parameter save. When parameter save is complete, Pr is reset to zero by the drive. The drive must not be in the under voltage (UU) condition for a save to take place. Saving parameters can take between 400ms and several seconds depending on the number of parameter values that are different from the values already saved in EEPROM. If the power is removed from the drive during a parameter save, it is possible for the EEPROM data to be corrupted giving an EEF failure when the drive is next powered Loading default parametersWhen default parameters are loaded, the new default parameter set is automatically saved to the drive Pr 29 in the Commander SK Getting Started Guide or Pr in this Advanced user Eur/USA parameter set differencesThe following table gives the differences between the Eur and USA default parameters sets.

The term 'rated drive current' is the value used by the software as rated current, which is not always the same as the drive rating specified in Pr (see section 4: Current control).
