9.4.2.6 '13.SL0' ... '33.SL20' Setpoint turning point
Adjustment range:
Purpose:
Factory setting:
Setpoint characteristic curves, standardization of manipulated variables, and tight closing
Input of the setpoint turning points is only possible if the "'12.SFCT' Setpoint function
(Page 161)" parameter is set to "FrEE". You can only enter one monotone rising
characteristic curve and two consecutive interpolation points must differ by at least 0.2%.

50:1
0.0 ... 100.0
These parameters are used to assign a flow coefficient in units of
5% to each setpoint turning point. The setpoint turning points form
a polyline with 20 linear segments which models the valve charac-
teristic; see figure below.
