40
40 Process PID set 1
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 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 also the control chain diagrams on pages 452 and 453.
To set the PID customer unit, select Menu - Primary settings
- PID - Unit on the panel.
