d) Sequence control
The following describes how sequence operations are controlled. Sequence control operations are
indicated in triangular brackets (< >).
Table4-7. Sequence Control
<Start>
Sets Run mode.
When changing from Idle mode, the operation goes to step 1 when <Start> is set,
and the sequence is started.
When changing from Hold mode, the sequence is resumed from where it was
stopped when <Hold> was set.
When <Hold> mode is set by the [step end] parameter, the sequence is resumed at
the step specified by [jump step] when <Start> is set.
<Hold> Changes from Run mode to Hold mode.
<Stop>
Changes to Idle mode.
Immediately changes to normal output step.
At that time, the values when <Stop> occurred are retained to the normal output step
[output parameter].
If it is tried to set the output voltage at <Stop> to exceed the setting range limit, then
the setting will change to 0 V. If it is tried to set the frequency out of the setting
range limit, then the setting will change to the lower limit of the setting range. The
output will turn off in these cases.
<Branch>
Changes to the step specified by [branch step].
Changes from the output at the time when <Branch> occurred to the [branch step].
