Note 1.
2.
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.
The load ratio ranging from 300 % to 350 % applies to the HG-KR servo motor.
