Description
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 40.07...40.56*, the
second set is defined by the parameters in group
PID set 2. The binary source that defines which set is used is
selected by parameter 40.57 PID set1/set2
See also the control chain diagrams on pages
*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 561.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
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 560.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
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 561.
This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit
Setpoint for process PID controller.
Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted by
parameter 40.31 Set 1 deviation

This parameter is read-only. The unit is selected by
parameter 40.12 Set 1 unit

Displays the trimmed reference output. See the control chain
diagram on page 561.
