Power and Encoder Interface One Cable Solution (OCS)


- Rotating plug connector with quick lock (connection lines between the encoder and drive controller are routed along in the motor's power cable).
- Option: Supplied with mating connector.
EZ Connection Method (OCS)
Winding Protection


PTC thermistors are installed in STOBER synchronous servo motors as a configuration feature to implement thermal winding protection. This makes it possible for the motor to exceed the maximum permitted winding temperature with the appropriate devices turned off.
