Specification

The Mitsubishi MR-J3-500B is a 5KW servo drive from the renowned MR-J3 series, engineered for superior motion control in automation systems such as CNC machines, robotics, and packaging lines. This model delivers exceptional performance with its advanced sine-wave PWM control, supporting both position, speed, and torque control modes. The MR-J3-500B operates on a 3-phase 200 to 230VAC supply and features a built-in regenerative resistor for efficient energy management. With a maximum input pulse frequency of 1Mpps (differential) and electronic gear functionality, it ensures precise positioning and high-speed response. The drive is fan-cooled (IP00) and rated for ambient temperatures from 0 to 55°C, making it suitable for harsh industrial environments.
