Initial value
Set "1" when a PID optional board (J-PI) is used.
The value entered to the OS terminal of J-PI is assumed as the target value.
The target value at set "1" is O-L, OI-L input signal,

If an analog voltage is entered as a feedback
value, the feedback voltage (0 to 10V)
corresponds to this target value level
setting (0 to 200%). In other words, if,
when 5V is entered as the target feedback
value of a sensor, it is converted to an
internal target value, set 100% as this
internal target value.
