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)

40.32 Set 1 gain
Defines the gain for the process PID controller. See
parameter
40.33 Set 1 integration time
.
1.00
0.01…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.
