| Abstract |
Due to the increasing automation of industrial plants more and more inverter-fed electrical drives are demanded which are able to fullfil decentralized tasks of plant-specific process control in addition to their drive-specific functions. This makes these inverters part of a distributed process control. In order to achieve an economical and suitable industrial solution a microcontroller-based process control module has been designed which is implemented into the inverter and used for processing application specific process control functions. This module is linked to the microcomputer of the drive control as an intelligent peripheral circuit. This system is especially suitable for fast real time applications. A winder control and a position control have been developed as typical applications for this process control module. The winder control allows open loop tension control with acceleration and friction compensation as well as closed-loop tension or dancer position contol. The position control has a highly dynamic perfomance due to a fast position control loop with short cycle times. |
