Description
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 591.
This parameter is read-only. The unit is selected by parameter
40.12 Set 1 unit selection.
PID deviation.
Displays the trimmed reference output. See the control chain
diagram on page 591.
This parameter is read-only. The unit is selected by parameter
40.12 Set 1 unit selection.
Trimmed reference.
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 = Trim function 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.
1 = Deadband active (see par. 40.39)
0 = Parameter set 1 in use. 1 = Parameter set 2 in use.
1 = Internal setpoint active (see par. 40.16...40.24)
Process PID control status word.
Activates/deactivates process PID control. See also
parameter 40.60 Set 1 PID activation
Note: Process PID control is only available in external control;
see section Local control vs. external control
Process PID control inactive.
Process PID control active.
Process PID control is active when the drive is running.
Selects the first source of process feedback. See the control
chain diagram on page 590.
