3.5.4.5 Io min and Io max
Io min
and
Io max
are an alternative method to using the set point and
amplitude values. Instead of thinking of the modulation as a
±
value around
the set point,
Io min
and
Io max
can be used to set the minimum and
maximum current points on the modulation waveform. They will, in effect,
change the modulation amplitude and current set point, and simply allow a
different method of inputting modulation information.
