8.4.3 SwitchingPIDAccordingtoSP
Description
ThezonePIDse
lectionbySPswitchesbetweenthegroupsofPIDparametersaccording
to the SP.
The maximum number of PID groups to be switched is 8. (Set RP1 to RP7)
The figure below shows the example of switching the group of PID parameters according
to the SP. It
