Sensorless vector control (SLVC)
If this motor control mode is set in
, a considerably higher torque and a lower current
consumption in idle state can be achieved compared to the V/f control mode.
Tip!
For vertical drives/hoists, use the servo control (with feedback), or the V/f control with
activated voltage vector control (VVC), which supports vertical drives/hoists up to 55 kW.
Note!
Observe the following application limits of the sensorless vector control:
• Only approved for power up to 55 kW and horizontal applications (no hoists or lifting
equipment)
• For single drives only
• For asynchronous motors only
• Not suitable for operation in generator mode/braking operation (e. g. unwinders)
