14.2 Installing a New Motor
(1) New motor unit
The new motor will be supplied together with the coupling installed as shown below.
Caution: The motor actuator cable exit direction varies depending on the actuator cable exit direction.
The cable exit direction must be the same for the motor to be removed and new motor to be
installed.
If the cable exit direction is different on the installed motor, deviation of the home position will
occur.
Caution: Align the home mark on the motor with the slit position on the coupling, and then install the
motor/coupling into the actuator.
Never loosen the coupling on the motor side.
The slit in the coupling is provided to help correlate the actuator and encoder positions. If the
coupling is loosened, home return may not achieve a normal home position.
(2) Aligning the slider position
[1] Use extension cables (motor/encoder cables) to connect the motor cable and the encoder cable of the motor
unit to the controller.
