MD800 - compact AC multi-drive

Save as PDF

The MD800 system consists of a common rectifier on the left side and up to four single- or dual-axis drive modules on the right side. Thus, up to eight drives can be combined in the same rectifier. The CANopen Interface is available as a standard, but also other common field-bus interfaces can be used.


  • Individual STO (safety torque off) function (according to SIL 3) for each drive
  • Suitable for open loop asynchronous and PM synchronous motors
  • 24-VDC control backup supply
  • IP40 rating
  • Remote LCD keypad (optional)
  • Commissioning PC software available
  • Dual rated:
    • heavy duty (HD, G rating): 150-% overload
    • normal duty (ND, P rating): 110-% overload
  • Reduced installation costs due to small footprint
  • Designed for harsh environment (high level conforming coating)
