Digital amplifier 4-Q for brushless motors with resolver

  • Digital Servo Amplifier MDR

MDR 230/5-10 MDR 230/10-20 MDR 400/2,5-7 MDR 400/5-11 MDR 400/8-17

Replaced by series MDR 2000, available only as spare part

Characteristics:

  • Short cycle times for the controller of the current, speed and positioning by using a high-speed 32 Bit-RISC-processor;
  • Suitable as controller of the speed and positioning with transfer of CNC-functions;
  • Operation master-slave with electronic gears;
  • High speed input for applications with sequential interruption;
  • Little space required by compact design and integrated intermediate circuit;
  • optimal using of the machine through rotor-oriented current regulation and sine formed current impression;
  • Network of different speed drive units by CAN-bus (optional) and/or supervising control unit;
  • Dimensions (without mating connector): W 70mm, H 200mm, D 210mm (W 90mm, H 200mm, D 210mm at MDR 400/8-17)
