MaxiDrive

Characteristics of the MaxiDrive servo drives
  • Digital servo drives for AC servo motors
  • Compact drives for control cabinet installation, complete with built-in power supply for direct connection to 3 × 400 V three-phase mains (3 × 480 V on request)
  • Design conforms to EMC requirements (CE marked; class A standard, class B through accessories)
  • Full digital servo drives with 2 processors: signal processor and 16-bit microcontroller
  • High dynamics and control quality through signal processor for digital control of current and speed (controller cycle time 62.5 Ásec)
  • Position control loop (cycle time 1 msec) integrated, setting the target positions via communication interfaces or positioning control with 500 blocks
  • 16 digital inputs, 8 digital outputs
  • Pilot frequency mode (pulse inputs, direction same as stepper motor controls) as an option
  • Communication via two serial ports, RS 232C, RS 485 (standard) and optionally Interbus, CANopen, or Profibus-DP according to DRIVECOM profile 22 or Sercos interface
  • Easy wiring, since all connections can be plugged in at the front and below
  • Comfortable installation, either using the plug-in DriveTerminal operator terminal or a personal computer
  • Operating modes and technology functions in command mode or program mode: torque mode, speed mode, profile position mode, electronic gearing, flying shear, electronic cam disk*, fine interpolation*
