EtherCAT P: The one cable solution – One step closer to automation without control cabinets

The EPP7041-3002 EtherCAT P Box is intended for the direct connection of different stepper motors. The PWM output stages for two motor coils cover a wide voltage and current range. The EPP7041-3002 can be adjusted to the motor and the application by changing just a few parameters. 256-fold micro-stepping ensures particularly quiet and precise motor operation. Connection of an incremental encoder enables a simple servo axis to be realized. Two digital inputs and a digital 0.5 A output enable connection of end switches and a motor brake.

The hardware- and software-based configuration make the stepper motor module particularly suitable for applications that are subject to unsteady motor operation due to natural resonance of the motor and the moved mass.
