Initial value
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.
Select whether to start auto tuning as well as a mode. When 1 or 2 is set, auto tuning is started
