8.4.3 Switching PID According to SP
Description
The zone PID selection by SP switches between the groups of PID parameters according
to the SP. The maximum number of PID groups to be switched is 4. (Set RP1 to RP3)
The figure below shows the example of switching the group of PID parameters according
to the SP. It shows an example of dividing the PV input range from the maximum value to
the minimum value into four zones by reference points 1 to 3. (Set RP1 to RP3.)

The PV input range can be divided into the number of zones that is set in the reference
point.
Reference deviation can be set at the same time.
