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