1. Connections of Power Supply

First, you will have to wire the main DC link or AC inputs to the model of the drive. However, for most of the ACOPOS drives, a line voltage of 230V or 400V three-phase has to be connected to the corresponding L1, L2, and L3 terminals.

2. Motor & Feedback Wiring:

The power cable for the servo motor is connected to the motor output terminals on the drive. The connection of the encoder or resolver cables, for position and speed feedback, to the feedback terminals on the drive is done.

3. Control Signals:

The B&R ACOPOS drives interface, through your PLC or motion controller, is by use of digital and analog inputs/outputs and a communication port like POWERLINK, EtherCAT, and CAN open, depending on the type.
