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 40.07...40.50, the second set is
defined by the parameters in group
The binary source that defines which set is used is selected
by parameter 40.57 PID set1/set2

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 453.
This parameter is read-only.
Process PID controller output.
Displays the value of process feedback after source
selection, mathematical function (parameter
feedback function), and filtering. See the control chain
diagram on page 452.
This parameter is read-only.
Process feedback.
Displays the value of process PID setpoint after source
selection, mathematical function
function), limitation and ramping. See the control chain
diagram on page 453.
