4.3 Overload protection characteristics (Important Points for Combining the drive unit MR-J4-DU55K_4 and
HA-LFS motor)
When using the drive unit MR-J4-DU55K_4 in combination with the HA-LFS motor, the overload protection
characteristics are as shown in the diagram.
For MR-J2S-55K_4, please check your operation pattern, since the overload protection curve (broken line) of
the overload ratio over 200% at the servo-lock is added.

Load ratio [%] (Note 1, 2)
Note 1. When the servo motor is stopped (servo-lock state) or is operating at a low speed of 30 r/min or
less, and an operation generating a torque of 100% or more of the rated torque is carried out at an
abnormally high frequency, there is a possibility that the servo amplifier may malfunction even
though it is within the electronic thermal protection.
2. The overload ratio over 100% indicates the rated output of a converter unit. For the rated output,
refer to section 1.2.1 of "MR-CV_/MR-CR55K_/MR-J4-DU_(-RJ) Instruction Manual".
