defines integral (reset) time. This action component
prevents stationary control deviations.
Notice
Changing this parameter has decisive effects on the
control action. A big integral action time in a slow
control, whereas a too small value can lead to over-
shooting and even to a destabilisation of the entire
control process.
0...120...3600 s
,
defines the derivative (rate) time for the differential
component. This component enables quicker reaction
to changes in the stationary status.
Notice
A modification of this parameter has decisive effects
on the control action. A too small derivative time ini-
tially produces drastic overhooting, whereas a too big
value produces oscillations and even destabilisation
of the entire control process.
