MRJ2S-40A MITSUBISHI Industrial Servo Drives 200-230V -10°C To 50°C 750W
MRJ2S-40A Description
The MR-J2S-40A is a high-performance, general-purpose single-axis AC servo amplifier from Mitsubishi Electric’s MELSERVO‑J2S series. Designed to drive 400 W class servo motors, it supports pulse train input for position, speed, and torque control, with fast response, high precision, and excellent stability. It features auto-tuning, anti-vibration control, and comprehensive protection functions, making it widely used in high‑speed automation machinery. The amplifier operates on 3‑phase 200–230 V AC power and is fully compatible with motors such as HC‑KFS43, HC‑MFS43, and HC‑MF43.
MRJ2S-40A Key Features
- High dynamic performance with speed loop bandwidth up to 250 Hz
- One‑touch auto‑tuning for quick commissioning and stable mechanical matching
- Built-in vibration suppression and resonance filtering for smooth low‑speed operation
- Supports position control, speed control, and torque control modes
