Single-Axis AC Servo Amplifier – MITSUBISHI MDS-C1-V1-35

The MDS-C1-V1-35 is a single-axis AC servo amplifier (“Single-Axis AC Servo Amplifier”) from the MDS-C1 series by Mitsubishi Electric, documented as a component of the MELDAS M60, M64 and M700 CNC systems for numerically controlled machine tools. It receives the DC bus voltage from the MDS-C1-CV power supply unit and drives the servo motor via PWM modulation, communicating with the CNC controller through the SSCNET II optical serial bus. Compatible with Mitsubishi Electric HF and HC series servo motors. The suffix “-35” denotes a peak rated current of 35 A; the designation V1 identifies the single-axis module, as opposed to the twin-axis V2 variant.

The servo amplifier is the power module that converts position and speed commands generated by the CNC into phase current for the motor: it closes the current loop and, in cascade, the speed and position loops, ensuring axis interpolation accuracy during machining. Should it fail, the controlled axis loses all servo movement, causing an immediate machine stop; in the most critical cases an abnormal current response can trigger uncontrolled movements and severe mechanical damage.

Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems and drives for machine tools, with over forty years of experience in industrial motion control. The MDS-C1 series has been superseded by the MDS-D and MDS-E/EX families; all products in the C1 family are therefore legacy / discontinued and available exclusively as used, surplus, or through specialist repair services.
