Mitsubishi MR-J4-10A1 AC Servo Amplifier for MELSERVO MR-J4

The Mitsubishi MR-J4-10A1 (MR-J4-10A1) is an AC servo amplifier drive developed for the MELSERVO MR-J4 motion control series. Designed for precise speed, torque, and position management, this drive unit incorporates a built-in dynamic brake and an integrated braking resistor to handle regenerative energy effectively during motor deceleration. The unit also features safety unit compatibility to support safe industrial machine operations. Operating across a 200 V to 240 V AC supply voltage class (220 V or 230 V AC) or 283 V to 340 V DC with single-phase, three-phase, or DC input capability, this amplifier provides a rated output of 1000 W (1 kW) with a rated current of 6 A. Built with an IP20 degree of protection, the servo drive is rated for ambient operating temperatures ranging from 0 to +55 degrees Celsius. It also incorporates RS-422 and RS-485 serial communication capabilities for system configuration, diagnostics, and multi-axis networking. Equivalent to MRJ4100ARJJ001, this servo drive is widely deployed in automated packaging, material handling, machining, and robotic motion systems.
