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.
