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 ).
