Description
Displays the value of process feedback after source
selection, mathematical function (parameter
feedback function), and filtering. See the control chain
diagram on page 403.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
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 404.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
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 404.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
PID deviation.
Displays the trimmed reference output. See the control chain
diagram on page 404.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
Trimmed reference.
Displays status information on process PID control.
This parameter is read-only.
