Product Title: Mitsubishi MR-J2S-60A MELSERVO J2S 600W AC Servo Amplifier

Mitsubishi Electric MELSERVO J2‑Super series MR‑J2S‑60A is a universal interface AC servo amplifier for precise motion control in industrial automation and OEM systems. Rated output 600 W at 200‑230 V AC, single‑phase or three‑phase input. Sine‑wave PWM control method with position, speed, and torque control modes. Speed loop frequency response of 550 Hz or higher supports high‑speed positioning applications. Built‑in dynamic brake and natural cooling. This product is discontinued and available as a spare part for maintaining existing MELSERVO J2S‑based systems.

Compatibility information:

• Compatible with Mitsubishi HC‑SFS series (medium‑inertia, up to 3000 rpm) and HC‑LFS series servo motors

• Compatible motors: HC‑SFS52 (600 W, 17‑bit encoder), HC‑SFS53, HC‑LFS52

• Compatible with HF‑KP and HF‑SP series servo motors (SSCNET version, MR‑J2S‑60A‑S004 variant)

• For detailed wiring, connector pinout, and parameter settings, refer to the MR‑J2S‑A Instruction Manual.

System Integration:

• This amplifier belongs to the Mitsubishi Electric MELSERVO J2‑Super series.

• Installs in control cabinet via panel mounting.

• Universal interface supports pulse train (differential line driver or open collector) and analog voltage commands.

• RS‑232C communication port (CN3) enables parameter configuration and monitoring via MR Configurator software.

• In absolute encoder mode, an external battery is required for position retention during power‑off.

Product Status:
Discontinued. Mitsubishi Electric has discontinued the MELSERVO J2S series. Repair service is no longer available. For new installations, use the recommended successor (MR‑J4‑60B).

Recommended Replacement:

• MR‑J4‑60B: MELSERVO‑J4 series 600 W servo amplifier with SSCNET III/H fiber‑optic communication, 22‑bit absolute encoder support, advanced vibration suppression control, and one‑touch tuning. Requires complete drive and motor replacement; not directly compatible with existing wiring or control systems without migration considerations. Renewal tool available for staged replacement.
