If the potentiometer settings for V
min
and V
max
restrict the
usable control range, this will change the characteristic
curve of the setpoint signal. Since the actual value
signal is always assigned to a characteristic curve of 0
V
nom
, a restriction of the usable control range results in a
different characteristic curve for 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 (rollover) calculation is not possible.
