Synchronous Motors Ver. 0002 SM - 13
SM.5.2 FEEDBACK CONNECTOR
Depending on the type of feedback integrated into the motor (encoder or resolver) the
connector will be either a 12-pin or a 9-pin.
SM.5.2.1 ENCODER FEEDBACK CONNECTOR
It is a 12-pin male Conney type connector which meets the IP65 sealing standard. The various
encoder types available use this connector.
The cable necessary to connect this connector with the drive module is the one referred to as
EEC. Chapter IN describes this cable in detail.
