Figure 15-14: Linear and Squared V/Hz Ratio
Figure 15-15: Programmable V/Hz Curve
Programmable V/Hz curve:
2 The V/Hz curve can be programmed with three different points. A
programmable V/Hz curve can be used if the other settings do not satisfy
the needs of the application.
Linear with flux optimization:
3 The drive starts to search for the minimum motor current in order to save
energy, lower the disturbance level and the noise. This function can be
used in applications with constant motor load, such as fans, pumps etc.
