Dual-Axis Servo Drive – Mitsubishi MDS-C1-V2-2020
The MDS-C1-V2-2020 is a dual-axis servo amplifier (“Dual-Axis Servo Amplifier”) manufactured by Mitsubishi Electric, belonging to the MDS-C1 series. It is documented as a component of Mitsubishi CNC systems including MELDAS 600, M64, M65 and related series. The V2 suffix denotes dual-axis configuration (two servo motors driven by a single module), while 2020 identifies the rated output current of 20 A per axis. Communication with the CNC controller is via the SSCNET optical serial bus (Servo System Controller NETwork), providing high immunity to electromagnetic interference. The module is compatible with Mitsubishi servo motors of the HF and HA series.
The MDS-C1-V2-2020 servo drive closes the position, speed, and current loops on two servo axes simultaneously: it receives position references from the CNC via SSCNET and generates the drive current required by the motors to execute interpolated axis movements with high precision. A failure of this module causes the immediate shutdown of both controlled axes, making any machining operation impossible until the unit is repaired or replaced.
Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems, industrial drives, and factory automation, with over a century of history in the electronics industry. The MDS-C1 series has been progressively replaced by the MDS-D and MDS-E/EX series; all MDS-C1 family products are therefore legacy / discontinued and available only as used, NOS (New Old Stock), or through specialist repair services.
