Product Overview
The Mitsubishi MR-J4-200A4-RJ is a 400V-class general-purpose interface servo amplifier belonging to the high-performance MELSERVO-J4 platform, with a rated output of 2.0 kW. The suffix A4 stands for three-phase 400V power specification, while RJ indicates built-in standalone positioning function and support for external linear/load-side encoder full closed-loop control via differential A/B/Z signal input. Requires specific motor cable wiring and parameter settings for full closed-loop mode activation.
This drive achieves up to 2.5kHz speed response bandwidth, equipped with advanced second-generation vibration suppression filters, one-touch auto-tuning, tough drive anti-disturbance function and machine diagnosis module to eliminate mechanical resonance and ensure ultra-smooth low-speed stable operation under heavy fluctuating loads. It supports three core control modes: position, speed and torque, and integrates STO safe torque off function complying with IEC/EN 61800-5-2 for equipment safety protection.
Compatible with Mitsubishi HG series 400V MELSERVO-J4 servo motors, it supports 4,194,304 pulse/rev high-resolution battery-backed absolute encoders and incremental encoders, removing repeated homing requirements after power loss. A built-in dynamic brake unit and comprehensive multi-layer fault protection guarantee long-term continuous operation. It is widely applied to heavy-duty CNC machine tools, metal processing equipment, large automated packaging lines, industrial robotics and semiconductor manufacturing machinery.
