AC Servo Drive 1 kW – MITSUBISHI MR-J2-100CT
The MR-J2-100CT is an AC servo amplifier from the MELSERVO-J2 series manufactured by Mitsubishi Electric, rated at 1 kW. It belongs to the second generation of the MELSERVO family and is designed for vector torque, speed and position control of Mitsubishi AC brushless servo motors in the HC-SF / HC-KF series. The CT suffix identifies a specific variant within the MR-J2 range. The drive is documented as a component of machining centres, CNC lathes, grinding machines and industrial automation systems equipped with Mitsubishi MELDAS CNC.
The servo drive is the heart of the controlled axis: it receives the position or speed reference from the CNC, reads the encoder feedback from the motor and generates the current required to follow the motion profile with maximum accuracy. In the event of a failure, the axis loses movement completely: the machine trips an alarm and cannot resume machining until the drive is replaced or repaired.
Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems, servo drives and industrial inverters, with over a century of history in power electronics and automation. The MELSERVO-J2 series was introduced in the late 1990s and equipped millions of machines worldwide before being superseded by the J3, J4 and J5 generations. MR-J2 products are legacy / discontinued: available exclusively as used, NOS surplus or through specialist repair.
