Mitsubishi's MR-J4-DU45KB4-RJ is an advanced servo drive with a substantial capacity of 45 kW. It functions within a voltage class of 400V and utilizes a command interface based on SSCNETâ…¢/H for streamlined communications with compatible devices. The drive outputs a three-phase AC with a rated voltage of 323V, complemented by a rated current of 131 A, making it suitable for demanding applications.

This unit can accept single-phase AC input ranging from 380V to 480V for the control circuit, operating at either a 50Hz or 60Hz frequency. Power management specifications indicate a required rated input current of 0.2 A for the control circuit power supply. The drive is designed to tolerate voltage fluctuations up to ±5%, ensuring it remains operational under varying power conditions.

Similarly, the frequency fluctuation is permissible at 45 W, solidifying its reliability for industrial applications. The operating requirements specify a power consumption of DC 24V at ±10%, aiding in efficient energy usage while supporting a current capacity of 0.3 A, which includes the CN8 connector signal. The interface power supply employs a sine wave PWM control method, which aligns with the current control method for accurate motor control.
