Single-Axis Digital AC Servo Amplifier – MITSUBISHI MDS-B-V1-35
The MDS-B-V1-35 is a single-axis digital AC servo amplifier (“Single Axis AC Servo Amplifier”) manufactured by Mitsubishi Electric, belonging to the MDS-B series. It is documented as a component of Mitsubishi CNC systems equipped with MELDAS 500/600 control units, installed in vertical machining centres and CNC lathes. It manages the position, speed and torque regulation loops of a single servo axis, communicating with the CNC unit via the high-speed serial bus SSCNET. Compatible with HC and HA series AC brushless servo motors from Mitsubishi Electric; peak output current is 35 A.
The servo amplifier is the core of axis control: it receives position and speed commands from the CNC unit and, comparing them with the motor encoder feedback, generates the current required to move the axis with maximum precision and repeatability. A drive failure renders the affected axis inoperable and triggers a machine alarm: production stops until the drive is repaired or replaced with a working equivalent unit.
Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems, servo amplifiers and motors for machine tools, with decades of experience in industrial motion control. The MDS-B series has been superseded by the later generations MDS-C, MDS-D and MDS-E; all MDS-B family products are therefore legacy / discontinued and available only as used stock, NOS (New Old Stock) or through specialist repair services.
