Characteristic curves Through the selection of the Start value and End value , the proportional
controller can be operated with a positive or negative characteristic cur-
ve.

Positive characteristic curve:
Select the
End value to be higher than the Start value .
The turn-on duration or frequency increases with an increasing mea-
sured value (see page 5-34).

Negative characteristic curve:
Select the
End value to be lower than the Start value .
The turn-on duration or frequency decreases with an increasing
measured value (see page 5-35).
The maximum values for the pulse width or switching frequency are
assigned to the
End value and the minimum values for turn-on duration
or frequency are assigned to the Start value .
