L-Series and FCS-18 Graphical User Interface User Manual
6.9 Phase controls
Phase
controls
affect one, two or
three phase
parameters at once.
The phases affected
can be selected
using the check
boxes located next
to each phase letter.
Changes made only
affect those phases which have a check mark. This allows changes to be
made to an individual phase as well as for multiple phases at once.

If the connected L-Series is a single phase unit only, phase B and C
controls are always disabled. If the connected L-Series is a two phase unit,
phase B is always disabled.
6.9.1 Voltage control
Voltage for each phase can be set using a left right slider control. The
operation of the slider control is similar to that of the frequency control. See
paragraph 6.4.
Voltage is limited on the low end to zero volts. On the high end, the
maximum voltage is determined by the hardware configuration of the
connected L-Series unit and the currently selected voltage range.
6.9.2 Current limit control
Maximum phase current can be set by using the current limit control. The
maximum value to which the current limit can be set is determined by a
combination of :
1. Power level of the connected L-Series unit
2. Voltage range selected. See section 6.5.
3. Phase mode selected (if MODE option available in three phase unit) See
section 6.6.
