MR-J4-10A Mitsubishi MR-J4-10A servo amplifier 0.1 kW, 1 ph/3 ph 220V, pulse/analog

The Mitsubishi MR-J4-10A servo amplifier from the MR-J4 series is a general-purpose drive rated at 0.1 kW for a 1/3-phase 220V supply, with a rated output current of 1.1 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-J4 motors — a coordinated amplifier-plus-servomotor pair within 0.1 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-J4-10A by the torque and dynamics of your cycle. We supply genuine Mitsubishi with CE certification, warranty and engineer-level technical support.

Mitsubishi MELSERVO MR-J4 is a mature servo drive series that has set the industrial standard for precise motion for years. Every amplifier carries a 22-bit absolute encoder, delivering over 4 million pulses per revolution and letting the axis position precisely without a homing run after power-up. The series comes in two interface variants: -A (general-purpose pulse-train and analog command for any PLC or controller) and -B (SSCNET III/H optical network for tight integration with the Mitsubishi motion line).

MR-J4 amplifiers pair with motors from the HG-KR family (low-inertia, 3000 rpm — for dynamic, fast cycles) and HG-SR family (medium-inertia, 2000 rpm — for higher torque and heavier loads). The 0.1–7 kW power range covers the 200V class (1-ph/3-ph 220V) and 400V class (3-ph 380V), flanges 40–176 mm, with or without a holding brake. Built-in auto-tuning and vibration suppression simplify commissioning.

MR-J4 is used in packaging and labelling machines, electronic assembly, CNC machine tools, conveyors, textile and printing equipment. We supply genuine Mitsubishi drives with CE certification, select the correct amplifier-and-motor pair for your torque and dynamics, and provide warranty plus engineer-level technical support at every stage — from selection to commissioning.
