Source selection (see Terms and abbreviations
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 112).
0.

Source selection (see Terms and abbreviations
Defines the gain for the process PID controller. See
parameter 40.33 Set 1 integration time.
Gain for PID controller.
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.

G × I
G × I
Ti
I = controller input (error)
O = controller output
G = gain
Ti = integration time
Note: Setting this value to 0 disables the "I" part, turning the
PID controller into a PD controller.
