11.1 Motor Replacement
This manual details the procedure for replacement of an ISWA/ISPWA Series motor.
When you need to replace your motor, please follow the steps described below.
Because the screws and other components removed during replacement of the motor will be
needed for reassembly, prepare a storage box in advance to keep those components so that you
don’t lose or misplace them.
CAUTION : When replacing the motor, ON/OFF operation of power supply and the servo is
required to perform the following processes;
(1) Aligning of the coupling on the motor
(2) Attaching the motor
(3) Brake Operation
Pay special attention on your work while the power is turned on.
Processes (1) and (2) are necessary to align the relative positions of the motor/
encoder unit and the actuator.
Without this positioning process, there may be a case that the home-returning
function does not correctly operate.
Process (3) is required because the brake is an electromagnetic brake, and it will
not be released without exciting it.
