If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo motor stop status (servo lock status) or in a 30r/min or less low-speed operation status, the driver may fail even when the electronic thermal relay protection is not activated.
If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo motor stop status (servo lock status) or in a 30r/min or less low-speed operation status, the driver may fail even when the electronic thermal relay protection is not activated. Note2. The load ratio ranging from 300% to 350% applies to the LE-servo motor.
