(Note 1) Load ratio [%]
MR-J3-11KT(4) MR-J3-22KT(4)
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 when the maximum torque of HF-KP servo motor is increased to 350%.
3. The load ratio ranging from 300% to 400% applies when the maximum torque of HF-JP servo motor is increased to 400%.
