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 30 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.
