MR-J5-500A Mitsubishi MR-J5-500A servo amplifier 5 kW, 3 ph 220V, pulse/analog

The Mitsubishi MR-J5-500A servo amplifier from the MR-J5 series is a general-purpose drive rated at 5 kW for a 3-phase 220V supply, with a rated output current of 28 A. The -A variant accepts a command in pulse/analog mode, so the drive integrates with virtually any vendor's control system without being tied to a specific bus.

• General-purpose pulse/analog control — positioning, speed and torque from any PLC, motion controller or pulse generator.
• Standalone operation — runs as an independent axis without requiring a proprietary network or master controller.
• Auto-tuning and vibration suppression — fast commissioning and stable motion without manual gain tweaking.
• Matched to MR-J5 motors — a coordinated amplifier-plus-servomotor pair within 5 kW.
• Advanced diagnostics and protection — overload monitoring, clear fault codes, predictive maintenance.

The drive suits packaging and labelling machines, electronic assembly, CNC machine-tool axes, conveyors, textile and printing equipment — wherever precise motion control from an existing controller is required.

We will match a suitable servomotor to MR-J5-500A by the torque and dynamics of your cycle. We supply genuine Mitsubishi with CE certification, warranty and engineer-level technical support.

Mitsubishi MELSERVO MR-J5 is the current flagship servo drive series. Its defining feature is a 26-bit absolute batteryless encoder (over 67 million pulses per revolution) that retains absolute position without a serviceable battery, eliminating scheduled replacements and unplanned downtime. The control loop runs roughly 50% faster than the previous generation, with enhanced vibration suppression for clean, stable motion at high speed. Interfaces available: -A (general-purpose pulse/analog) and -B (SSCNET III/H).

MR-J5 pairs with new-generation motors HK-KT (low-inertia, 3000 rpm — for fast, dynamic applications) and HK-ST (medium-inertia, 2000 rpm — for higher torque and medium capacity). Range 0.1–7 kW, 200V class (1-ph/3-ph 220V) and 400V class (3-ph 380V), flanges 40–176 mm, with or without a holding brake. Higher torque density and finer feedback yield better cycle repeatability.

The series fits applications where speed and precision are critical: electronic assembly, pick-and-place, robotics, CNC machine-tool axes, high-speed packaging and printing. We supply genuine Mitsubishi drives with CE certification, select a matched amplifier-and-motor pair for your task, and provide warranty plus engineer-level technical support at every project stage.
