Servo Drive Technology

TrioDrive D

Characteristics of the TrioDrive 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
  • 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 (standard) or positioning control with 500 blocks (option)
  • 8 digital inputs, 4 digital outputs
  • Pilot frequency mode (pulse inputs, direction 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 or Sercos interface
  • Easy wiring, since all connections can be plugged in at the front and at the top
  • Comfortable installation 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*
