 Start Phase (StartPhs)
Determines the phase of AC waveform when the step starts.
-------- Notes ------------------------------------------------------------------------------------------------------------
 Step Start Phase setting can be disabled. In that case, the phase when the phase starts becomes
the phase when the previous step ended.
 In DC mode, the step Start Phase cannot be set.
-----------------------------------------------------------------------------------------------------------------------------
 Stop Phase (Stop Phs)
Determines the phase of AC waveform when the step ends. When the stop phase setting is active, the
execution waits for the Step Time that was set pass, and keeps the output setting until it reaches the
Stop Phase that was set, and then transitions to the next step. As the result, the actual step time is
longer by one cycle at a maximum than the set Step Time. Figure 4–3 shows an example where both
the Stop Phase of the previous step and the Start Phase of the next step are set to 0°.

Notes ------------------------------------------------------------------------------------------------------------
 When the Step Behavior is set to [Sweep], output is constant while waiting for the step Stop
Phase after the Step Time passes.
 Step Stop Phase setting can be disabled. In this case, when the set Step Time has passed, the
execution transitions to the next step without waiting for step Stop Phase.
 In DC mode, the step Stop Phase cannot be set.


Trigger output (Trig Out)
State output to CONTROL I/O connector. This specifies whether the trigger output presents when
the step starts. Polarity and pulse width of the trigger output complies with the trigger output setting
(see
4.2.5 ).
