Custom U/f ratio

The user can define a U/f curve (output voltage as a function of frequency). This
custom ratio is used only in special applications where linear and squared U/f ratio
are not sufficient (e.g. when motor break-away torque needs to be boosted).

Note: The voltage and the frequency points of the U/f curve must fulfill the following
requirements:

and
2611
WARNING! High voltage at low frequencies may result in poor performance or motor
damage (overheating).
