TIP
How switching of a PID parameter group is carried out depends on the PID selection method. Normally, it
is controlled by the SP Number Selection (SPNO) operation control parameter. In Zone PID mode, the
proportional band, integral time and other PID control-related parameters are switched according to the
zone PID setting. For details on the Zone PID mode, see Section C6.9, "PID Selection Method (SP
Number Selection, Zone PID Selection)."
