Mitsubishi's MR-J4-70B-KS is an advanced servo drive designed for high-performance applications. This unit connects through RS-422/485 and SSCNET III communication ports, enabling efficient communication within automated systems. It operates on a 3-phase AC voltage of approximately 200 to 230 V, accommodating a ±10% variation.

Providing an output power of 700 W, the drive can handle a rated output current of 5.5 A. The feedback mechanism utilizes an absolute encoder, which allows for precise positioning with an accuracy of ±0.01 arc-min, contingent on the motor in use. The maximum operational speed is up to 3000 RPM, demonstrating its capability in high-speed applications.

For thermal management, it employs forced air cooling to maintain operational efficiency. The device operates effectively within a temperature range of 0°C to 55°C. Its compact design measures approximately 50 mm in width, 150 mm in height, and 160 mm in depth, with a total weight of about 1.5 kg.

Safety features such as Safe Torque Off (STO) and Safe Stop 1 ensure the drive maintains operational integrity, contributing to overall system reliability. The control type encompasses vector control as well as position control, providing flexibility to meet various application needs. The rated output voltage for this drive can vary between 100 V and 120 V, depending on the specific drive configuration utilized.
