Description
Parameter values for process PID control.
The drive output can be controlled by the process PID.
When the process PID control is enabled, the drive
controls the process feedback to the reference value.
Two different parameter sets can be defined for the
process PID. One parameter set is in use at a time. The
first set is made up of parameters 40.07...40.50, the
second set is defined by the parameters in group
Process PID set
2. The binary source that defines which
set is used is selected by parameter
selection.
See also the PID control chain diagrams in chapter
Control chain
diagrams.
Displays the output of the process PID controller. See the
control chain diagram on page 507.
This parameter is read-only.
Process PID controller output.
Displays the value of process feedback after source
selection, mathematical function (parameter
feedback
function), and filtering. See the control chain
diagram on page 507.
This parameter is read-only.
Process feedback.
Displays the value of process PID setpoint after source
selection, mathematical function
(40.18 Set 1 setpoint
function), limitation and ramping. See the control chain
diagram on page 507.
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
inversion. See the
control chain diagram on page 507.
This parameter is read-only.
PID deviation.
Displays the trimmed reference output.
This parameter is read-only.
Trimmed reference.
