Specification

The Mitsubishi MR-JE-300A is a robust 3KW servo drive engineered for demanding industrial automation applications. As part of the MR-JE series, this model delivers precise speed, torque, and position control with a high-resolution 131072 pulses/rev encoder feedback. It features advanced vibration suppression and adaptive filtering to ensure smooth operation even in challenging mechanical setups. The drive accepts 3-phase 200-240V AC input with a permissible voltage fluctuation of 170-264V AC, making it versatile for global installations. With a rated output current of 11A and a main circuit input current of 14A, the MR-JE-300A is ideal for driving medium to large servo motors in packaging, material handling, and CNC machinery.
