Description
Displays the value of process feedback after source
selection, mathematical function (parameter
feedback function), and filtering. See the control chain
diagram on page 430.
This parameter is read-only.
Process feedback.
Displays the value of process PID setpoint after source
selection, mathematical function
function), limitation and ramping. See the control chain
diagram on page 431.
This parameter is read-only.
Setpoint for process PID controller.
Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted by
parameter 40.31 Set 1 deviation
chain diagram on page 431.
This parameter is read-only.
PID deviation.
Displays status information on process PID control.
This parameter is read-only.
Value
1 = Process PID control active.
1 = Process PID setpoint frozen.
1 = Process PID controller output frozen.
1 = Sleep mode active.
1 = Sleep boost active.
1 = Tracking function active.
1 = PID output is being limited by par. 40.37.
1 = PID output is being limited by par. 40.36.
0 = Parameter set 1 in use. 1 = Parameter set 2 in use.
1 = Internal setpoint active (see par. 40.16...40.16)
Process PID control status word.
Activates/deactivates process PID control.
Note: Process PID control is only available in external
control; see section Local control vs. external control
86).
Process PID control inactive.
Process PID control active.
