Mitsubishi MR-PWR-R-600-6,7 Braking Resistor for MELSERVO Drives

The Mitsubishi MR-PWR-R-600-6,7 (MR-PWR-R-600-6,7) is an external regenerative braking resistor designed for use with Mitsubishi MELSERVO series servo drive systems. During rapid deceleration, dynamic stopping, or continuous braking of servo motors, excess kinetic energy is converted into electrical energy and fed back into the drive intermediate DC bus. This regenerative power resistor safely dissipates that surplus regenerative energy as thermal heat, protecting the servo amplifier from overvoltage faults and maintaining stable continuous operation in demanding motion control applications. Rated for power dissipation in heavy-duty automated machinery, the unit features a nominal power rating of 600 W and a resistance of 6.7 ohms, perfectly matched to the regenerative circuit requirements of compatible Mitsubishi servo drives. With a net weight of approximately 10 kg, this robustly constructed resistor assembly is suitable for mounting within industrial control cabinets or machinery enclosures across automated packaging, material handling, CNC machine tools, and textile manufacturing lines. It ensures reliable equipment protection during high-duty cycling and repeated stop-start processes.
