The MR-J4-20GF model, part of Mitsubishi's MELSERVO MR-J4 series, offers reliable performance for various control applications in industrial environments. Outputting 200 watts, this servo drive requires a 3-phase AC power supply that operates between 200 and 230 volts with a tolerance of ±10%. It delivers a rated output current of 1.8 A and efficient voltage levels between 100 and 120 V.

Effective thermal management is vital for performance; here, the MR-J4-20GF uses forced air cooling to maintain optimal temperatures during operation. The device can function within a temperature range from 0°C to 55°C, allowing it to adapt to different environmental conditions. Its dimensions measure approximately 50 mm in width, 150 mm in height, and 160 mm in depth, with a weight of around 1.5 kg, making it compact yet robust for industrial use.

Safety is prioritized in this unit with features such as Safe Torque Off (STO) and Safe Stop 1, ensuring operational safety during emergency situations. The drive supports various control types, including vector control and position control. Users can expect a maximum speed of up to 3000 RPM, although this speed depends on the specific motor being used.

For integration, the MR-J4-20GF has communication ports that include RS-422/485 and SSCNET III, enhancing its compatibility with different control systems. It also utilizes an absolute encoder for reliable feedback. Achieving a positioning accuracy of ±0.01 arc-min (depending on the motor), this unit is suitable for applications that demand precision and reliability.
