8.2.1.5 PID 2
Figure 13 PID 2 controller
The PID 2 controller is identical to PID 1. PID 2 does not have an integral cut-off frequency, because when
combining two PID controllers this is only needed at the controller which has to drive the output with the
higher bandwidth (usually PID 1). Instead it comprises an additional low-pass output filter (see āSystemā in
section 8.2.4).
NOTE ! When the controller is not selected for AutoLock, it can be used as an independent con-
troller (Manual Mode).
