Effective drive control

December 2000 Motion Control & Drives

Shorrock Automation's AC1150 module provides a simple, yet effective method of controlling SEW's MOVIMOT drives. All modes, functions and status indications of the drive can now be controlled directly from the AS-Interface with a specially developed module designed and manufactured by IFM Electronic. Input and output bits are passed onto the SEW inverter by means of an RS485 link. The conversion from AS-Interface to RS485 is done electronically; therefore there is no extra work involved for the user.

Four different modes are available to operate the drive. These modes vary from selecting preset speeds to controlling the drive with a standard analog function block that enables the drive to perform as a VSD. The AS-Interface system supplies 24 V to the drive eliminating the need for any additional power supplies.
