Control
(1) Suppress output exceeding
a: Decrease derivation time (D value)
b: Extend integration time (I value)
(2) Suppress output oscillation
a: Decrease derivation time (D value) or set it as 0
b: Decrease proportionality constant (P value)

0: PID target value refers to the value set as in P159.
1: PID target value refers to the value of external analog 0-10V (corresponding to 0-100%)
and the value set as in P159 is invalid.
Target value selection can be set via selection panel and external analog which is 0-10V
signal or set through potentiometer.
