the PHASE key on the front panel. The selected phase is always shown in the top right hand
corner of the WAVEFORMS display.
To select the same wave shape for all three phases in a three-phase configuration, press the
PHASE key until the “øABC” enunciator appears in the top right corner of the WAVEFORMS
menu. Waveform selections made in this mode will apply to all three phases.
4.4.3 Creating Custom Waveforms
The 3Pi controller provides four groups of 50 custom defined waveforms each for a total of 200
waveforms in addition to the 3 standard waveforms. Of these four groups, one may be active at a
time. The active group is selected in the INITIAL SETUP menu.
Custom waveforms cannot be created from the front panel of the MX Series. Rather, they have
to be downloaded through one of the remote control interfaces. A Windows based program is
included with the MX Series that allows waveforms to be created and downloaded easily. This
Graphical User Interface program allows waveforms to be created by specifying harmonic
amplitudes and phase angles with respect to the fundamental. It also offers an arbitrary
waveform data entry mode that allows individual data points to be specified.

Once downloaded, waveforms remain in non-volatile memory and will be visible in the
WAVEFORMS menu for selection. The user can assign a 12-character name to each custom
waveform. Avoid using any of the standard waveform names (SINE, SQUARE or CLIPPED) as
these names will not be accepted.
Waveforms may be deleted using the remote control interface as well. Custom waveforms
cannot be deleted from the front panel however to avoid accidental erasure.
