Measuring and control unit for an exhaust gas test bench with EtherCAT fieldbus

The project objective was the development and production of an EtherCAT fieldbus node with Linux-based control unit and EtherCAT master for an exhaust roller test bench with up to 16 drives of 200 kilowatts each and numerous auxiliary drives. Flexible EtherCAT fieldbus nodes for measurement data acquisition, motor control and data communication had to be developed. A robust design for use in harsh test bench environments, dynamic control of the forces to be simulated within a few milliseconds and precise synchronization of the individual drives were essential requirements.
