Motion EP7342, ER7342 Motion | DC motor output stage EtherCAT Box 286 DC motors can replace the considerably more expensive servomotors in many applications if they are operated with an intelligent controller. A DC motor can be integrated very simply into the control system using the EP7342/ER7342 EtherCAT Box. All parameters are adjustable via the fieldbus. The small, compact design and the possibility to fit the modules directly to machines makes the EtherCAT DC motor output stage suitable for a wide range of applications. The output stage is protected against overload and short circuit and offers an integrated feedback system for incremental encoders. Two DC motors can be controlled by one module.

The speed or position is specified by the automation device via a 16 bit value. By connection of an incremental encoder, a simple servo axis can be realised. The output stage is protected against overload and shortcircuit.

EP8309, ER8309 Special functions Special functions | Multi-functional I/O box The EP8309-1022/ER8309-1022 EtherCAT Box has various digital and analog inputs and outputs: eight digital inputs/outputs, two digital tacho inputs, two analog inputs, one analog output and a 1.2 A PWMi output. The current signals have 12-bit resolution. The tacho outputs supply a speed-dependent velocity or frequency value via digital 24 V sensors. Proportional valves, for example, can be actuated directly using the PWMi output, while intelligent valves are switched by the analog output. With its combination of inputs and outputs, the EP8309-1022/ ER8309-1022 offers a compact solution for the most diverse units that can be controlled over EtherCAT.
