Re-consider the capacity of the
motor, monitor the U0-02 torque
during operation, whether it is in
the value of more than 100 for a
long time, if yes, please chose the

(1) Enhance ventilation measures
to reduce ambient temperature;
(2) Check whether the fan rotates
when the servo is enabled; when
the module temperature U-06
≥45℃, the fan opens.
Alarm when motor

① Check whether the motor fan
is abnormal
② Contact the manufacturer for
