MidiDrive D
MidiDrive D servo drives are available for replacement needs only. Please see Servo Drives New Generation or MidiDrive D/xS for current series of digital AC servo drives with similar power.
Characteristics of the MidiDrive D 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 230 V AC or 3 × 400 V three-phase mains
- 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 µs)
- Position control loop (cycle time 1 ms) integrated, setting the target positions via communication interfaces (standard) or internal positioning control with 500 blocks (option)
- 8 digital inputs, 4 digital outputs
- Pilot frequency mode (pulse, direction inputs same as stepper motor controls) as an option
- Communication via one serial port, RS 232C (standard) and optionally Interbus, CANopen, or Profibus DP according to DRIVECOM profile 22
- Easy wiring, since all connections can be plugged in at the front and at the top
- Comfortable commissioning using 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*
