If the potentiometer settings for q
vmin
and q
vmax
restrict
the usable control range, this will change the character-
istic curve of the setpoint signal. Since the actual value
signal is always assigned to a characteristic curve of
0 q
vnom
, a restriction of the usable control range results
in a different characteristic curve for the setpoint value
and actual value signal.
In this case, a direct inference due to different signal
voltages at the setpoint value input or actual value
output without a (rollover) calculation is not possible.
