Figure 5-28.Transients Settings.
The SETTINGS menu has the following fields:
Entry Description
Phase Sets the output phase to which the programming of the transients
will be applied.
Time Sets the units for the time of the transient step; the default units
are in seconds. Alternatively, the time could be changed to
cycles of the output frequency. Note that time durations in
seconds may result in rounding errors if the period of the
programmed frequency is not an integer number of milliseconds.
For example, for 50 Hz output (20 ms period), no rounding errors
occur, but for 60Hz (16.66 ms period) a rounding error would
occur when converted. The time duration scale selection affects
both the Time and End Delay parameters.
Volt(age) Sets the units for voltage values; the default units are in V(RMS).
V is the RMS value of the output voltage, while % is the
percentage of the steady-state setting.
Freq(uency) Sets the units for frequency values; the default units are in Hz.
Hz is the value of the output frequency, while % is the percentage
of the steady-state setting.
Start Phase A Shows the start phase angle of the voltage transient in degrees.
Only one start phase angle per transient sequence is allowed.
The start phase angle must be in the first transient event of the
list. The start phase angle is not valid for DC transients.
Step Defines how the step sequence of the transient list is executed;
the default is All:
All: All of the steps in the sequence are executed without breaks.
One: Each step is executed one at a time.
Trig(ger) The present state of the trigger settings are shown in the TRIG
field. Tap on the field to open the TRIGGER sub-menu to change
settings; refer to Figure 5-29.
