For PID1 feedback, two targets are selected, feedback
data 1 and feedback data 2, the result of the operation
carried out between these two constitutes the PID1
feedback value.

・
If [PIDC] terminal is active (ON), the value of the integral
constant is purged. If done while operating, the
operation can become instable/insecure.
・
With [PRO] terminal, the gain can be changed. If the
state is OFF, Gain 1 is used, if the state is ON, Gain 2 is
used.
