The Mitsubishi MR-J2-70C, which belongs to the MELSERVO MR-J2 series, operates as a highly effective position controller. It can handle a 3-phase power supply of 200-230VAC or a 1-phase supply at 230VAC, suitable for typical industrial needs. The voltage fluctuation range for 3-phase systems is 170-253VAC, and for 1-phase systems is 207-253VAC. The controller effectively handles frequency fluctuations within ±5%, ensuring precise control.
Utilizing either sine-wave PWM or current control methods offers a speed frequency response rating of 250Hz or more, which is crucial for applications requiring quick adjustments. The integrated dynamic brake enhances control during operation, contributing to the device's overall reliability. The MR-J2-70C features a standard point table capacity for up to 3 points, making it suitable for various positioning tasks. Overspeed protection is also incorporated, ensuring safe operation under all conditions.
This unit supports RS-422 (and 232C) communication protocols, facilitating connectivity with other devices. It successfully manages single-axis positioning functionalities, providing versatility in use. The device's construction follows an open structure, promoting ease of access for adjustments and maintenance. Designed to perform in an operating temperature range of 0 to 55°C, the MR-J2-70C can also be stored at temperatures between -20 and 65°C, ensuring reliability in various environments.
