General Information
The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect installation or adjustment of the optional
parameters of the equipment or from mismatching the variable speed drive with the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of 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 content of the guide without
notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form or by any means, electrical or mechanical including,

Drive software version
This product is supplied with the latest version of user-interface and machine control software. If this product is to be used in a new or existing system
with other drives, there may be some differences between their software and the software in this product. These differences may cause the product to
function differently. This may also apply to drives returned from the Control Techniques Service Centre.
If there is any doubt, please contact your local Control Techniques Drive Centre or Distributor.
Environmental Statement
Control 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 Environment Policy and other relevant 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 long working lifetime. In typical applications, these positive environmental
effects far outweigh the negative impacts of product manufacture and end-of-life disposal.
Nevertheless, when the products eventually reach the end of their useful life, they can very easily be dismantled into 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 screws.
Virtually all parts of the product are suitable for recycling.
Product 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 from wrapping product, can be recycled in the same way. Control Techniques' packaging strategy favours easily recyclable
materials of low environmental impact, and regular reviews identify opportunities for improvement.
When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.

If the Control Techniques Commander SK2202 motor cannot overcome the load on the belt when the start button is pressed, possible issues include:

1. Low AC supply voltage – Insufficient voltage may prevent the motor from generating enough torque.
2. Low DC bus voltage – This can occur if supplied by an external DC source or during fast deceleration.
3. Mechanical load driving the motor – The load may be too heavy or moving in the opposite direction.
4. Drive requires autotuning – If the motor or its connections have changed, re-autotuning is needed.
5. Incorrect deceleration or ramp settings – Fast ramp times may not allow proper acceleration.

Check supply voltage, mechanical load, and ensure the drive is properly tuned to the motor.
