Other [bit] Source selection (see Terms and abbreviations on page 144). -
40.31 Set 1 deviation
inversion
Inverts the input of the process PID controller.
0 = Deviation not inverted (Deviation = Setpoint - Feedback)
1 = Deviation inverted (Deviation = Feedback - Setpoint)
See also section Sleep and boost functions for process PID
control (page 101).

40.32 Set 1 gain Defines the gain for the process PID controller. See
parameter
40.33 Set 1 integration time.
1.00
0.10…100.00 Gain for PID controller. 100 = 1
40.33 Set 1 integration
time
Defines the integration time for the process PID controller.
This time needs to be set to the same order of magnitude as
the reaction time of the process being controlled, otherwise
instability will result.
Note: Setting this value to 0 disables the “I” part, turning the
PID controller into a PD controller.
