Mitsubishi MR-J4-70TM-PNT AC Servo Drive for MELSERVO-J4 Series

The Mitsubishi MR-J4-70TM-PNT (MR-J4-70TM-PNT) is an AC motion servo drive and amplifier developed for the MELSERVO-J4 series. Engineered for precise motion control, this unit operates with a three-phase 380 to 480 VAC or 283 to 340 VDC power supply in the 400 V class. It incorporates an integrated dynamic brake and built-in braking resistor to safely handle regenerative energy and manage dynamic deceleration during industrial machine cycles. The servo amplifier is also compatible with external safety units to support secure machinery operation. Featuring an IP20 degree of protection, the drive is designed for cabinet installation in environments with an operating temperature between 0 and 55 degrees Celsius. Communication capabilities include RS-422 and RS-485 interfaces, allowing seamless integration with industrial controllers and motion networks. The unit delivers a rated output of 3.5 kilowatts (3500 watts) with a rated current of 8.6 amperes, making it suitable for multi-axis machinery, packaging systems, assembly automation, and advanced manufacturing equipment requiring synchronized motion and reliable performance.
