*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.
