Mitsubishi's MR-J4-40A1 is a sophisticated servo amplifier from the MELSERVO MR-J4 series, engineered for dynamic and precise control tasks. With a rated output current of 2.0 A, this amplifier is adept at managing performance while ensuring responsive operation. It supports a rated output voltage range from 200 V to 230 V with minor fluctuations tolerated (+/- 10%).

This model features advanced control methodologies, including position control and vector control, allowing it to adaptively respond to different operational demands. It can achieve maximum speeds of up to 3000 RPM, conditions permitting based on the specifications of the connected motor. Powering this amplifier requires a 3-phase AC supply, providing an output power rating of 400 W or 0.4 kW.

Communication interfaces are crucial for integration within automated systems, and this device offers both RS-422/485 and SSCNET III ports. Moreover, feedback is delivered through an absolute encoder, ensuring high fidelity in motion resolution. The positioning accuracy achieved can be as precise as ±0.01 arc-min, contingent on the motor utilized. To maintain operational efficiency, the device employs forced air cooling to dissipate heat effectively, contributing to prolonged lifespan and consistent performance under load.
