MDS-A-V1-45 Mitsubishi Servo Drive

The Mitsubishi MDS-A/B Series MELDAS AC Servo/Spindle Systems is a drive system where MDS-A Series corresponds to the MELDAS M500 Series NC that has been developed to totally connected the servo drive and spindle drive sections. The Mitsubishi MDS-B Series is the successor to the MDS-A Series and as been developed to satisfy European Safety Standards. This Series has the following features:

Compact and Lightweight:
The Converters that were conventionally built-in each servo and spindle drive have been integrated into one unit. The drive system volume, installation are and weight have been drastically reduced with the incorporation of high density mounted electronic parts IGBT-IPM (Intelligent Power Module) and high performance heat radiating fin.

Low Heat Generation:
By incorporating the IPM and using power supply regeneration in the servo drive, the amount of heat generated has been greatly reduced.

High Speed and Precision Processing:
A high speed CPU has been mounted on the control PCB, and a 100,000 pulse/rotation sub micron detector has been incorporated as a standard to allow faster and more precise interpolation.
By incorporating the stable position loop control (SHG Control) method, having an outstanding response, the positioning time and tracking have been improved and the machine vibration during acceleration/deceleration has been reduced.
The cutting performance and cutting precision during position control have been improved by using the high speed CPU also for the spindle drive.

High Speed Spindle Orientation:
Smooth operations and minimum orientation times have been realized by using the high speed orientation method while allows direct orientation from high speed during the spindle drive.
