When orientation, etc., is carried out using an external encoder, a motor detector cable and encoder
cable are connected using a forked cable from the connector (CN2).
Note that when the cable shield is not connected to the ground via the connector case, the shield should
be securely connected to the ground using a cable clamp jig, etc., as shown in the drawing. If the shield
is not connected to the ground, it may cause the motor to produce abnormal noises or the orientation
position to deviate.
