SEW motors of the „DFS / CFM“ series

The holding brake of the SEW motors has to be connected via a brake rectifier, to guarantee the “quick activation of the brake”. A 3 wire connection cable is required for this. The following schematic diagram shows the correct connection of the motors to the AX5000.

• Motor brake cable ZK4500-4xxx (2)
• SEW BMV5 brake rectifier (3)
• Power supply with 5 A minimum output current (4)
