Note 1. 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 50 r/min or less low-speed operation status, the servo amplifier may malfunction
regardless of the electronic thermal protection.
2. The load ratio ranging from 300% to 350% applies to the HG-KR servo motor.
3. The operation time at the load ratio of 300% to 400% applies when the maximum torque of HG-JR servo motor is increased to
400% of rated torque.
