How to read a Mitsubishi servo amplifier model number

Part of the model What it tells you
MR-J2S, MR-J3, MR-JE, MR-J4 The amplifier series. Amplifier and servo motor series must match
Suffix A General-purpose interface: pulse train, analog speed or torque command
Suffix B SSCNET III network interface, used with Mitsubishi motion and PLC controllers
Number before the suffix Capacity: for MR-JE, 10 = 100 W, 20 = 200 W, 40 = 400 W, 70 = 750 W, 100 = 1 kW

Quote the complete model from the amplifier’s rating label, for example MR-JE-40A, and tell us the servo motor model on its nameplate (HF-KP, HG-KR, HC-KFS and similar).

Common alarm codes and what to check

Alarm Meaning First checks
AL.10 Undervoltage Supply dip, loose power terminals, failed charging circuit
AL.16 Encoder initial communication error 1 Encoder cable, connector, motor encoder
AL.20 Encoder normal communication error 1 Cable damage, noise, encoder fault
AL.30 Regenerative error Regen resistor, wiring, excessive regeneration
AL.32 Overcurrent Motor or cable short, power stage fault
AL.33 Overvoltage Fast deceleration, regen resistor, supply surge
AL.45 Main circuit device overheat Cooling, ambient temperature, overload
AL.50 Overload 1 Mechanical load too high, brake or mechanical binding
AL.52 Error excessive Position command ahead of motor: check mechanics and gains

Alarm numbers and wording differ slightly between series. Confirm in the manual for your exact model.

Frequently asked questions

What is the difference between MR-J3 and MR-JE?

MR-J3 is the earlier series and MR-JE is the newer, more compact series for general-purpose machines. They use different parameters and often different motors, so one is not a drop-in swap for the other. Ask us before ordering across series.

What does the A or B at the end of the model mean?

A is the general-purpose interface using pulse train or analog commands. B is the SSCNET III network interface used with Mitsubishi motion controllers and PLCs. Replace like with like.

Can I replace an MR-J2S with an MR-JE?

Not directly. The series use different motors, encoders, connectors and parameters, so a change needs a motor and wiring review. If you need the same amplifier, we can look for an MR-J2S in stock.

Are the amplifiers tested before dispatch?

Yes. Used and refurbished amplifiers are checked on our bench before dispatch, and the condition is stated on each listing.

What should I send to confirm the right amplifier?

Send a photo of the amplifier rating label and the servo motor nameplate. We confirm the series, capacity and interface before you order.

Do you ship across India with a GST invoice?

Yes. Every order gets a GST invoice and is dispatched from Puducherry to anywhere in India.
