Parameters 317
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
