4035 PID OUT
FREEZE
Freezes the output of the process PID controller. This
feature is useful when the reference is based on a process
actual value connected to an analog input, and the sensor
must be serviced without stopping the process.
The output of the PID controller is frozen as long as the
selected digital input is ON for parameter values DI1 … DI5
or OFF for parameter values DI1(INV) … DI5(INV) .
See also parameter 4034 .
