8-4 Overload Characteristics
(Electronic Thermal Function)
An overload protection (electronic thermal) function is built into the Servo Drive to protect the Servo
Drive and Servomotor from overloading.
If an overload does occur, eliminate the cause of the error and then wait at least one minute for the
Servomotor temperature to drop before turning on the power again.
If the power is turned ON again repeatedly at short intervals, the Servomotor windings may burn out.
