7.1.11 Modulation of integral action time Tn
The integral part (= adjustment time) determines the dynamic
behaviour of the controller and thus the time required by the
controller to adjust for the actual control deviation. The adjustment
time is independent of the amount of deviation.
behaviour of the controller and thus the time required by the
controller to adjust for the actual control deviation. The adjustment
time is independent of the amount of deviation.
7.1.12 Modulation of runtime
This function allows adjusting the actuator, with regard to its finite
running time, to the control characteristics, meaning that actuators
with different runtimes react to the same deviation by readjusting
by the same amount through adapting the action times. The
integral action time Tn remains unchanged in this. However, care
must be taken that the latter must always exceed the runtime of
the respective actuator.

7.1.13 Modulation of start time
The start time parameter determines the length of the start-up
phase in modulation mode so that a stable start-up is ensured. As
soon as the set start time has expired, the modulation switches to
its normal control characteristics defined by the modulation
parameters.
