1.4.3 Function and parameterization of the V/f Control (V/f Reg Param)
1.4.3.1 V/f Regulation Control (V/f Control)
When the motor is loaded, the mechanical speed changes according to the applied load.
In order to reduce the speed error, it is possible to compensate for the motor slip.
The function parameterization allows:
- to increase the output voltage with low frequencies (voltage Boost)
- to compensate the speed change due to a load increase
- to parameterize a filter on the compensation
- to damp the DC link oscillations
The V/f mode has no current regulator.
A pseudo-regulator changes the output frequency in order to prevent the current from overcoming the set current limit.
