Parameter values for process PID control.Process PID set 140
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 40.07…40.56*, 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 section Process PID control (page 72), and the control
chain diagrams on pages 640 and 641.
*The remaining parameters in this group are common for
both sets.
- / real32Displays the output of the process PID controller. See the
control chain diagram on page 641.

This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
1 = 1 / 10 = 1Process PID controller output.-32768.0 ... 32767.0
- / real32Displays the value of process feedback after source
selection, mathematical function (parameter 40.10 Set 1

diagram on page 640.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.

- / real32Displays the value of process PID setpoint after source
selection, mathematical function (40.18 Set 1 setpoint

diagram on page 641.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.

32767.00
- / real32Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted

control chain diagram on page 641.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit selection.
