User Guide Unidrive model sizes 1 to 5 Unidrive LV model sizes 1 to 3 Universal Variable Speed Drive for induction and servo motors Part Number: 0460 – 0070 Issue Number: 6 General information The 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 (Drive) with the motor. The contents of this User 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 User Guide, without notice. All rights reserved. No parts of this User Guide may be reproduced or transmitted in any form or by any means, electrical or mechanical including photocopying, recording or by any information- storage or retrieval system, without permission in writing from the publisher. Important... 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 with other Control Techniques variable speed drives in an existing system, there may be some differences between their software and the software in this product. These differences will cause a difference in functions. This may also apply to variable speed drives returned from a Control Techniques Service Centre. If there is any doubt, contact a Control Techniques Drive Centre. Copyright © October 2000 Control Techniques Drives Ltd Author: RFD Issue Code: udxu6 Issue Date: October 2000 S/W Version: 03.XX.07 onwards Addendum Using the Unidrive with ramps disabled (closed loop only) When using the Unidrive in Closed-Loop mode (Vector or Servo) with the acceleration/deceleration ramps disabled (Pr 2.02 = 0), the stop mode (Pr 6.01) must be set to no.rP. If this is not done, the Drive may allow the motor to momentarily start running up in the forward direction following the removal of the run reverse command. More information: When using the Unidrive with the ramps disabled (Pr 2.02 = 0), the stop mode at the default value (Pr 6.01= rP) and the Drive running with full reference in the reverse direction; on the removal of the run reverse command the final speed reference will momentarily go positive and will return to zero at a rate dependant on the deceleration ramp (default setting = Pr 2.21). If an application requires the ramps to be disabled (either in Closed-Loop Vector or Servo mode), the stop mode [06.01] should be set to no.rP. An alternative solution is to set the deceleration ramps to 0 (zero).

Default configuration 2. Operating mode 3. User-interface mode 4. Macro configuration Each of the upper layers (2, 3, 4) is superimposed on its preceeding layer. 1.4 Default configurations The Drive has a separate default configuration for the AC supply conditions in Europe or in the USA. These two default configurations are distinguished as follows: European AC supply voltage at 50Hz USA AC supply voltage at 60Hz The Drive is despatched from the factory in the appropriate default configuration for the continent in which it is to be sold. The default configuration is Macro 0 (described in Macro configurations later in this chapter). The default configuration also defines the following functions: Europe • Ability to select positive-logic for the digital control inputs • Ability to adjust the current-loop PI gains USA • Ability to select digital control by two or three wires • Frequency/speed demand indication (These functions apply to Macro 0 only.) Key used in this User Guide The following key denotes the default configuration: EUR> 50Hz AC supply (Europe) USA> 60Hz AC supply (USA) When no key is stated, the information applies to both default configurations. 1.5 Operating modes The Drive can be configured to operate in any of the following operating modes. Open-loop For use with standard AC induction motors. uploads/Litterature/ uni-drive-user-guide.pdf
