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 (eg, 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:
2610 < 2612 < 2614 < 2616 < 2618 and
2611 < 2613 < 2615 < 2617 < 9907
WARNING! High voltage at low frequencies may result in poor performance or
motor damage (overheating).
