(2) Reduce the acceleration and deceleration of the work cycle to lower the motor
load.
(3) Apply external forced air cooling to the servo motor using cooling fans or other

Note: do not place a gasket or other insulating materials between the servo motor and
heat sink, as this may result in motor temperature increase, noise resistance being
affected, and motor malfunction.
