1-Phase Mode
Figure 5-20. DASHBOARD Screen Top-Level Menu for Source Mode
The following selections are available in the DASHBOARD screen top-level menu. Functions that accept
a numeric value require that the value is within the allowed range, otherwise, an error will be generated,
and the value will not be accepted.
When the unit is configured for 3-Phase output, each phase has individual settings. When the unit is
configured for 1-Phase output, only Phase-A is displayed. Tapping on a phase button toggles the selection
of that phase for inputting values. When a phase is selected, its button is displayed with a green color.
When a phase is not selected, its button is displayed with a gray color. When all phases are selected, entry
for one phase will make the same changes for the other phases.
Entry Description
Setting
VOLTAGE Programs the output voltage in RMS value, V(RMS), when in
AC-mode and DC mode, and the AC component when in
(AC+DC) mode. In (AC+DC)-mode, the DC component is
programmed using the DC OFFSET sub-menu in the OUTPUT
PROGRAM menu. In DC mode, negative values can also be
entered. Refer to Section 5.6.4.
CURRENT Programs the output current in RMS value, A(RMS). Refer to
Section 5.6.4.
FREQUENCY Programs the output frequency in Hz when in AC mode. If the unit
is in DC mode, the value for FREQ will be set to DC and cannot
be changed until AC mode is selected. When in AC-mode, the
frequency can be changed from 16 Hz to 905 Hz (depending on
options, for HF option unit 905 Hz and standard unit 550 Hz).
Refer to Section 5.6.4.
RANGE Displays 166 VAC or 333 VAC range for AC-mode and
AC+DC -mode (range may vary depending upon the unit’s XVC
option), and 220 VDC or 440 VDC range for DC-mode operation.
The OUTPUT state must be OFF for a change in range to be
executed.
MODE Displays the source mode of operation either AC or DC or
AC+DC mode.
OP MODE Displays the current operating mode.
