Parameters 235
40
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
, the
second set is defined by the parameters in group
. The binary source that defines which
set is used is selected by parameter
See also the PID control chain diagrams in chapter
Displays the output of the process PID controller. See the
control chain diagram on page
This parameter is read-only.
0.00
-200000.00…
200000.00%
Process PID controller output.
1 = 1%
Displays the value of process feedback after source
selection, mathematical function (parameter
), and filtering. See the control chain
diagram on page
.

0.00
-200000.00…
200000.00 PID
customer units
Process feedback.
1 = 1 PID
customer
unit
Displays the value of process PID setpoint after source
selection, mathematical function (
), limitation and ramping. See the control chain
diagram on page
.

0.00
-200000.00…
200000.00 PID
customer units
Setpoint for process PID controller.
1 = 1 PID
customer
unit
Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted
by parameter
. See the
control chain diagram on page
This parameter is read-only.

200000.00 PID
customer units
PID deviation.
1 = 1 PID
customer
unit
Displays the process PID trimmed reference output. See
control chain diagram on page
This parameter is read-only.
