Digital 4-Q Amplifier for brushless motors with resolver

  • Digital Servo Amplifier MDR 2102 / 2105

MDR 2102, MDR 2105

The MDR 2000 series is an intelligent AC Servo inverter with integrated Positioning control. The single-phase devices MDR 2102 and MDR 2105 are suitable for synchronous and linear motors of up to 1.0kW rated power.

  • Substantial parameterization possibilities and extension options for flexible use
  • Universal encoder interface, adjustment of the encoder via Software
  • Integrated active PFC stage (Power Factor Control) to fulfill standards of the limitation of mains harmonics, achieving additional up to 30% higher rotational speed
  • Integrated CAN-Bus Interface, other field bus options available, for example Profibus
  • 2 technology slots for field bus modules and additional digital I/O

In addition to point-to-point positioning, speed and angle synchronization with electronic gear, the implemented CANopen protocol DSP402 allows the realization of contouring controls with linear interpolation as well as time-synchronized multi-axis applications.
The MDR 2300 can convey sequences over the integrated course program of up to 256 position sets without an external PLC.
With the active PFC stage it is possible to use a wide voltage range, Alternatively, motors with higher torque constants at identical power ratings can also be used.
With the menu-driven Configuration Tool Mattke "ServoCommander™" and the automatic motor identification, the MDR 2300 quickly and comfortably adapts to your requirements.

Features

  • short cycle times for the current, speed and position control by using a high speed 23-bit RISC processor
  • operating as speed and position controller with take over of CNC functions
  • Master-Slave operation with electronic gear
  • high speed input for sequential applications
  • reduced need of space by compact structural shape and integrated intermediate voltage
  • optimal use of the machine capacity by rotor oriented current regulation and sinusoidal current form
  • interconnection of the speed drives by CAN-bus, Profibus (optional) and/or a central CNC unit
