220 Parameters
40.30 Set 1 setpoint
freeze enable
Freezes, or defines a source that can be used to freeze, the
setpoint of the process PID controller. This feature is useful
when the reference is based on a process feedback
connected to an analog input, and the sensor must be
serviced without stopping the process.
1 = Process PID controller setpoint frozen
See also parameter 40.38 Set 1 output freeze enable.
Not selected
Not selected Process PID controller setpoint not frozen. 0
Selected Process PID controller setpoint frozen. 1

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 57).
