PV start: When the program control starts, SV and step time are advanced to the PV,
then the program control is performed.
However, if the value set during the [Step SV setting when control starts]
and the step SV are equal, or if the value set during the [Step SV setting
when control starts] is higher than PV, PV start is cancelled, and
SV start is adopted.
When Wait function is set, the function has priority.
SV start: When the program control starts, the program control starts from the
value which has been set during the [Step SV setting when control
starts].
