MITSUBISHI MR-J2S-100A AC Servo Amplifier 1kW 200V

Buy online your MITSUBISHI MR-J2S-100A AC Servo Amplifier 1kW 200V reference MR-J2S-100A from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This is a MITSUBISHI MELSERVO-J2-Super 1 kW axis amplifier used to drive 200 V class servo motors on CNC and general automation equipment. It closes the power stage between the motion controller and the motor, providing precise current and speed control with auto tuning and integrated protections. Commonly sourced as a replacement unit or spare part for machine downtime recovery, it suits maintenance teams handling legacy Mitsubishi servo systems.

The unit accepts 200 to 230 V AC supply and supports single phase or three phase input for flexible installation in existing cabinets. Rated output is 170 V, 0 to 360 Hz, 6 A, sized for the 1 kW motor class. The amplifier works with HC-KFS, HC-MFS and HC-UFS series motors in the 200 V family, which makes it practical for mixed fleets on the production floor. The standard command interface used on A-type models allows pulse train positioning commands as well as analog speed or torque control, so it integrates cleanly with many CNC and PLC controllers already set up for J2S drives.

Auto tuning helps establish stable gains after a field replacement, and the drive includes protection against overload, overvoltage and short circuits to safeguard motors and upstream control hardware. The front panel indicators and alarm reporting support quick fault tracing. If you are facing AL.E9 or E10 events, swapping in a known good MR-J2S-100A is a common diagnostic step to separate amplifier issues from wiring or motor faults.

Reference: MR-J2S-100A

Manufacturer: MITSUBISHI

Product type: MITSUBISHI Servo drive MR-J2S

Main function: 1 kW axis servo amplifier for 200 V class Mitsubishi HC series motors with pulse and analog command support

Applications: CNC axis control on machining centers and lathes, automated assembly, feeders, pick and place, packaging equipment and retrofit projects using 200 V Mitsubishi servo systems

Key technical data: Input 200 to 230 V AC, 50 or 60 Hz, single phase or three phase, 5 A nominal. Output 170 V, 0 to 360 Hz, 6 A. Power rating 1000 W. Auto tuning function. Integrated protections for overload, overvoltage and short circuit. Standard interface for general use on J2-Super platforms. Compatible with HC-KFS, HC-MFS and HC-UFS motors in the matching rating.

In industrial maintenance this model is frequently used as a drop in replacement to recover a stopped axis after amplifier failure or repeated alarms. Many shops keep a stocked spare on the shelf to limit repair turnaround when a drive trips during production. It is also suitable for retrofit and like-for-like replacements on older lines still running the J2-Super family.

For service work, technicians often confirm system health by installing a known good amplifier, checking command signals and confirming motor thermal and encoder feedback before returning the machine to service. Keeping one or two units in industrial spare inventory helps shorten unplanned stoppages and supports preventive maintenance planning on legacy equipment.

Each unit can be tested on CNC simulators with matched Mitsubishi servo motors by skilled engineers, with functional checks on command interface, enable chain and fault reporting. Packaging is designed for industrial transit with ESD and shock protection. Many stocked items ship directly from our Florida facility. Backed by our standard warranty for professional buyers of automation parts.

This model is widely used as an emergency spare for aging installations where sourcing an identical amplifier keeps the machine running without parameter overhauls. Cnc-shopping USA supports obsolete part sourcing, and repair service or exchange service may be available for customers maintaining older J2-Super systems and surplus stock strategies.

Frequently asked questions about MR-J2S-100A:

Which motors pair correctly with this amplifier
It is intended for 200 V class HC-KFS, HC-MFS and HC-UFS motors in the 1 kW range. Always confirm motor nameplate current and series to match the 1 kW rating.

What power supply is required
The amplifier operates on 200 to 230 V AC at 50 or 60 Hz and accepts single phase or three phase input. Proper grounding and upstream protection should match local electrical codes and the drive rating.

Is this a direct replacement for MRJ2S100A or MR-J2S-1OOA
Yes, those markings are common alternate references for the same model. Verify the label on your existing unit for the exact code before ordering.

What command signals does the A-type interface support
The A-type version supports standard pulse train positioning and analog speed or torque commands used by many CNC and PLC motion controllers. This allows a straightforward panel swap without changing the control strategy.

How are alarms like AL.E9 or E10 handled during troubleshooting
These events can result from amplifier faults, wiring issues or motor problems. Maintenance teams often install a known good replacement unit to isolate the cause, then proceed with wiring and motor checks if the alarm persists.
