(6) Connect the HS-MF23 relay connector in a relay box having a structure (IP54) that prevents water,
oil and dust, etc., from entering. Fix the enclosed cable to the motor, and also fix the enclosed
cable to the motor.
5-1-6 Cable stress
(1) Sufficiently consider the cable clamping method so that bending stress and the stress from the
cable's own weight is not applied on the cable connection.
(2) In applications where the servomotor moves, make sure that excessive stress is not applied on
the cable.
Select the cable bending radius from the required bending life and wire type.
Fix the detector cable and power cable enclosed with the servomotor.
(3) Make sure that the cable sheathes will not be cut by sharp cutting chips, worn by contacting the
machine corners, or stepped on by workers or vehicles.
