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
.

and

To set the PID customer unit, select
Menu - Primary settings
- PID - Unit
on the panel.
Displays the output of the process PID controller. See the
control chain diagram on page
This parameter is read-only.

Process PID controller output.
1 = 1 PID
customer unit
Displays the value of process feedback after source
selection, mathematical function (parameter
), and filtering. See the control chain
diagram on page

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
.
This parameter is read-only.
-
-200000…200000
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…
200000.00 PID
customer units
PID deviation.
1 = 1 PID
customer unit
No.
