Parameters 2334040 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 drivecontrols the process feedback to the reference value.Two different parameter sets can be defined for theprocess PID. One parameter set is in use at a time. Thefirst set is made up of parameters 40.07…40.50, thesecond set is defined by the parameters in group 41Process PID set 2. The binary source that defines whichset is used is selected by parameter 40.57 PID set1/set2selection.See also the PID control chain diagrams in chapterControl chain diagrams.To set the PID customer unit, select Menu - Primarysettings - PID - Unit on the panel.40.01 Process PID outputactualDisplays the output of the process PID controller.
