Phase Angle Control; Waveform Type Selection - Ametek L Series User Manual

L-Series and FCS-18- Graphical User Interface User Manual

6.9.3 Phase angle control

Phase angles can be set for each phase individually. Note that setting the
phase angle for phase A with an internal clock reference has no effect as
phase A will be used as the reference. Phase angle for phase A is only
meaningful if external sync is used. External sync is not supported by the
LSGUI program at this time.

6.9.4 Waveform type selection

Based on the connected L-Series configuration, different types of
waveforms can be selected for each of three phases. The relevant controls
will be available to the user if the waveform options are supported by the
connected L-Series unit. Specifically, the following configurations are
required to support the different waveforms :
Sine
Clipped
Square
46
Supported by all L-Series AC sources
Only available with -PT type controller. Creates sine waveforms
with total harmonic distortion ranging from 0 to 20 %
Only available if Square wave option is installed in the L-Series
unit. See the System Settings screen for information on
installed options. (Refer to section 5.2)
