Mitsubishi Electric MELSERVO MR-J servos

MR-J is Mitsubishi Electric’s servo amplifier line: current MR-J5, the widely installed MR-J4, and discontinued MR-J3 and MR-J2S.

In the amplifier code the number is the rating (e.g. 40 = 400 W) and the last letter the interface (A = pulse/analog, B = SSCNET III, G = CC-Link IE TSN, etc.).

Amplifier and motor must match, so please include the motor model (HG-KR, HF-KP…). Discontinued MR-J3 and MR-J2S are sourced from remaining stock.
