4.5.7 Continuous controller with position controller
( Cntr/ C.Fnc = 6 )
Basically, this controller function is a cascade. A slave controller with three-point
stepping behaviour working with position feedback Yp as process value (INP2 or
INP3) is added to a continuous controller.
ConF / Cntr SP.Fn = 0 setpoint controller
C.Fnc = 6 continuous controller with
position controller
C.Act = 0 inverse output action
(e.g. heating applications)
ConF / InP.2: I.Fnc = 3 position feedback Yp
S.typ = 50 sensor e.g. potentiometer 0..160 Ω
ConF / Out.1: O.Act = 0 direct output action Out.1
Y.1 = 1 control output Y1 active
Y.2 = 0 control output Y2 not active
ConF / Out.2: O.Act = 0 direct output action Out.2
Y.1 = 0 control output Y1 not active
Y.2 = 1 control output Y2 active
PArA / Cntr: Pb1 = 0,1...9999 proportional band 1 (heating)
in units of the physical quantity
(e.g. °C)
ti1 = 1...9999 integral time 1 (heating) in sec.
td1 = 1...9999 derivative time 1 (heating) in sec.
t1 = 0,4...9999 min. cycle tim 1 (heating)
SH = 0...9999 switching difference
