Specification

The Mitsubishi Servo Drive MR-JE-300B represents a state-of-the-art solution for high-torque, high-speed servo applications, delivering 3KW of rated output power with a robust 11A rated current. Engineered for the MR-JE-B Series, this drive operates on a 3-phase 170V AC to 264V AC power supply (50/60 Hz) and integrates sine-wave PWM/current control for exceptionally smooth motor operation. Its built-in 100W regenerative resistor and dynamic brake provide reliable energy dissipation and rapid stopping capabilities, while the advanced servo functions—including auto tuning, one-touch tuning, tightening & press-fit control, and lost motion compensation—ensure optimal performance in packaging, textile, and material handling systems. The drive also features a USB interface for easy PC connection via MR Configurator2 software, and its IP20-rated forced cooling design guarantees stable operation in ambient temperatures from 0°C to 55°C.
