Voltage Frequency Control (VFC)
Sensorless Flux Control (SFC)
- Only for asynchronous motor
Field-Oriented Regulation (FOR)
- Only for asynchronous motor
Attention: With the SFC motor control mode (Sensorless Flux Control)
no lifting drives and no applications with regenerative load
torque 1) can be operated at present.
1) All machinery counteracts the drive with a static torque. The static
torque is generally termed load torque. If this load torque acts in the
direction of movement, such as in lifting mechanisms, during lowering,
then the term “regenerative load torque” is used.
Note: During operation intensive load peaks or unintentional
cancelling of the start effects in a loss of stator flow control of
the SFC-control. So that a current overload shut-off or
uncontrolled movements can occur.
