4.4.5 Continuous controller (inverse)
ConF / Cntr: SP.Fn = 0
set-point controller
C.Fnc = 1
continuous controller (PID)
C.Act = 0
inverse action
(e.g. heating applications)
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
PArA / Cntr: Pb1
= 0,1...9999
proportional band 1 (heating)
in units of phys. 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 time 1 (heating)
PArA / SEtP: SP.LO = -1999...9999 set-point limit low for Weff
SP.Hi = -1999...9999 set-point limit high for Weff
g
For direct action of the continuous controller, the controller action must be
changed (
ConF / Cntr / C.Act = 1 ).
g
To prevent control outputs
Out.1 and Out.2 of the continuous controller from
switching simultaneously, the control function of outputs
Out.1 and Out.2
must be switched off (
ConF / Out.1 and Out.2 / Y.1 and Y.2 = 0 ).
