Vector control

For highest demands on the drive behaviour of the three-phase motor, the SLV method is practically extended by the feed back of the actual motor speed. However, a sensor such as an incremental encoder on the motor shaft is necessary, which measures the actual motor speed and feeds it back to the control loop. The following advantage result compared to the extra effort in addition to the SLV process:

  • Shortest reaction time with setpoint changes
  • Shortest response times with load changes
  • Highest torque, even at speeds = 0 Hz (static torque)
  • Highest torque, even at speeds = 0 Hz (static torque)

If drive qualities of this kind are necessary, the Moeller frequency inverter DV6 can be expanded by the encoder module DE6-IOM-ENC.
