Drive Units

Drive Units High-gain servo spindle drives, capable of fully enhancing drive system performance

High-performance Servo/Spindle Drive Units MDS-E/EH Series

  • The servo control-dedicated core processor realizes an increase in control speed, leading to improved basic performance. When combined with a higher resolution motor sensor and enhanced high-speed optical communication, this drive contributes to high-speed, high-accuracy control.
  • Motor power connector comprises an anti-misinsertion mechanism. This helps to eliminate connection errors.
  • Improved diagnostic and preventive-maintenance features.
  • Safe Torque Off (STO) and Safe Brake Control (SBC) are supported in effort to enhance safety features.

Multi-hybrid Drive Units MDS-EM/EMH Series

  • The multi-hybrid drive unit is capable of driving a maximum of three servo axes and one spindle. This contributes to the downsizing of machines and offers technical advantages.
  • Motor power connector comprises an anti-misinsertion mechanism. This helps to eliminate connection errors.
  • Safe Torque Off (STO) and Safe Brake Control (SBC) are supported in effort to enhance safety features.
  • Fan unit contributes to easier fan exchange.
  • MDS-EMH 400V system drive unit is available.

All-in-one compact drive units MDS-EJ/EJH Series

  • Ultra-compact drive units with built-in power supplies contribute to reduced control panel size.
  • The 2-axis type is added for further downsizing.
  • The servo control-dedicated core processor realizes an increase in control speed, leading to improved basic performance. When combined with a higher resolution motor sensor and enhanced high-speed optical communication, this drive contributes to high-speed, high-accuracy control.
  • Safe Torque Off (STO) and Safe Brake Control (SBC) are supported in effort to enhance safety features.
  • MDS-EJH 400V system drive unit is available (For servo motors only).

High-performance Servo/Spindle Drive MDS-D2/DH2 Series

  • With the fastest current control cycle, basic performance is drastically enhanced (High-gain control). A combination of high-speed servo motor and high-accuracy detector helps enhance overall drive performance.
  • A high-efficiency fin and low-loss power module have enabled unit downsizing, which also leads to a reduction in control panel size. A line of drive units driving a maximum of two spindles is available, contributing to a reduction in control panel size.

All-in-one compact drive units MDS-DJ Series

  • Ultra-compact drive unit, which has built-in power supply, contributes to the reduction in size of control panels. The 2-axis type is added for further downsizing.
  • A high-efficiency fin and low-loss power module have enabled unit downsizing, which also leads to a reduction in control panel size.

Multi-hybrid Drives MDS-DM2 Series

  • A line of high-performance multi-hybrid drive units are available. The multi-hybrid drive unit drives a maximum of three servo axes and one spindle, supporting the ownsizing of units and offering technical advantages.
  • A power regeneration system that efficiently uses energy during deceleration as power contributes to highly-frequent acceleration/deceleration and energy savings.

SiC Power Module-installed Multi-hybrid Drive MDS-DM2-SPHV3

  • Realizes higher spindle speed and lower energy consumption.
  • Drives spindle motors at higher speed with greater torque, while maintaining the same size as conventional models.
  • Enables greater spindle motor torpue, up by 15% compared to conventional models.
  • Drives spindle motors at speeds up to 30,000 rpm, twice as fast as conventional models.

Servo / Spindle Drive MDS-C1/CH Series

  • High-speed high-accuracy machining is supported by high-speed current control (High-gain control I).
  • Downsizing is realized by adopting high-efficiency spiral fin and low-loss power module.
  • Offering full lineup in both 200V/400V power source to support all the users in the world.
  • The machine-end detector and linear-scale interface are equipped as standard (V1/V2)

High Cost-performance Servo Drive MDS-R Series

  • Excellent cost-performance is achieved by adopting resistance regeneration type and 2-axis-integrated servo drive.
  • High-speed current control (High-gain control I) and Smooth high-gain(SHG) control contributes to high-speed high-accuracy machining.

Small-capacity, Compact Servo / Spindle Drive MDS-B-SVJ2/SPJ2 Series
