224 Parameters
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
41 Process PID set 2
. The binary source that defines
which set is used is selected by parameter
40.57
PID
set1/set2 selection
.
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.

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

unit
Displays the value of process PID setpoint after
source selection, mathematical function (
), limitation and ramping. See the
control chain diagram on page
.

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.

customer units
PID deviation.
1 = 1 PID
customer
unit
Displays the process PID trimmed reference output.
See control chain diagram on page
