ZPA operation with EP7402

An EP7402 contains two motor controllers. Thus, only one EP7402 is required to control two zones.

ZPA communication

In ZPA mode, communication is required between the motor controllers of adjacent zones.

The internal ZPA communication between the two motor controllers within an EP7402 is done via internal variables.

The external ZPA communication between the motor controllers of two adjacent EP7402 is optionally performed by one of the following mechanisms:

• Switching signals of the digital inputs/outputs (X01, X02, X05, X06) via M8 cables. (factory setting)
  
• EtherCAT communication via a controller.
