4.5.2 2-point and continuous controller (inverse)
ConF / Cntr SP.Fn
= 0 set-point / cascade controller
C.Fnc
= 1 2-point and continuous controller (PID)
C.Act
= 0 inverse action
(e.g. heating applications)
ConF / Out.1: O.Act
= 0 action Out.1 direct
Y.1
= 1 control output Y1 active
ConF / Out.3: O.tYP
= 1 / 2
Out.3 Type ( 0/4 … 20mA)
Out.0
= -1999...9999 scaling analog output 0/4mA
Out.1
= -1999...9999 scaling analog output 20mA
O.Src
= 1 controller output y1 (continuous)
PArA / Cntr: Pb1
= 1...9999 proportional band 1 (heating)
in units of phys. quantity (e.g. °C)
ti1
= 0,1...9999 integral time 1 (heating) in sec.
td1
= 0,1...9999 derivative time 1 (heating) in sec.
t1
= 0,4...9999 min. cycle time 1 (heating)
PArA / SEtP: SP.LO
= -1999...999 set-point limit low for Weff
SP.Hi
= -1999...9999 set-point limit high for Weff
g
For direct action, the controller action must be changed
(
ConF / Cntr / C.Act = 1 ).
