Parameter values for process PID control.
The drive contains a single active PID controller for process
use, however two separate complete set-ups can be
programmed and stored.
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 section
(page
), and the control
chain diagrams on pages
and
*The remaining parameters in this group are common for both
sets.
Displays the output of the process PID controller. See the
control chain diagram on page
This parameter is read-only. The unit is selected by parameter
.

-32768.00 …
32767.00
Process PID controller output.
1 = 1 unit
Displays the value of process feedback after source selection,
mathematical function (parameter
), and filtering. See the control chain diagram on page
This parameter is read-only. The unit is selected by parameter
.
-
-32768.00 …
32767.00
Process feedback.
1 = 1 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. The unit is selected by parameter
.
-
-32768.00 …
32767.00
Setpoint for process PID controller.
1 = 1 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. The unit is selected by parameter
.
