For permanently stable contact, the connector
has to be in a vertical position.
Install a strain relief so that no force is applied to
the connector.
Encoder connection for hybrid cables
Hybrid cables (e.g., RHB2‑021DDB) connect the drive controller to the motor
(XZ03) and encoder (XG20).
Form a loop to lead the encoder cable to the connection point XG20 so that no
force is applied to the encoder connector:
