Specification

The Mitsubishi MR-JE-70A is a high-reliability servo drive designed for 700W class servo motors, delivering exceptional performance in industrial automation applications. This model features a rated output voltage of 3-phase 170 V AC and supports a wide input voltage range of 170 V AC to 264 V AC (3-phase or 1-phase) with a frequency tolerance of ±5%. The drive incorporates advanced control algorithms, including sine-wave PWM and current control, ensuring precise motion control with minimal torque ripple. Its built-in regenerative resistor handles up to 20W of regenerative power, while the dynamic brake provides safe and rapid deceleration. The MR-JE-70A is equipped with a high-resolution encoder interface (131072 pulses/rev) and supports electronic gear ratios for flexible positioning. With a rated current of 5.8 A and a mass of 1.5 kg, this unit is optimized for space-saving cabinet installations. It offers robust protective functions such as overcurrent, overvoltage, and overload shut-off, making it a dependable choice for critical automation systems.
