The Mitsubishi MR-J4-20B1-RJ belongs to the MELSERVO MR-J4 product line, developed for meticulous motor management. This servo drive is specified to output currents of 1.8 A and operates at voltages between 100 and 120 V, tailored to drive specifications. It achieves an output power rating of 200 W, making it suitable for diverse applications.

Powering this device involves a 3-phase AC input ranging from 200 to 230 V ±10%. The drive excels in vector and position control methods, allowing for high precision operations, with maximum speeds reaching up to 3000 RPM, contingent upon the connected motor.

For feedback, this model uses an absolute encoder system that enhances its effectiveness in tracking position. The positioning accuracy is remarkably fine, rated at ±0.01 arc-min, which is subject to the motor specifications.

Communication capabilities are well-supported with both RS-422/485 and SSCNET III ports, ensuring compatibility with various control setups. The MR-J4-20B1-RJ also incorporates forced air cooling for efficient thermal management. Furthermore, the operating temperature range for this servo drive extends from 0°C to 55°C, allowing it to function under varied conditions.
