1.1 Configuring Wiring System Settings
This section explains the following wiring system settings.
• Wiring system
• Efficiency equation
• Turning independent element configuration on and off
• Delta computation
• Display format of external current sensor range
• Deskewing (correcting the transfer time difference between input signals)
► Features Guide: “Wiring System Settings (WIRING)”
WIRING Menu
Press WIRING to display the following menu.
Set the display format of external current sensor range
(Direct, Measure).
Turns independent element configuration on and off
Set delta computation.
Set the efficiency equation.
Set deskewing.
Set the wiring system.
Setting the Wiring System
Press the Wiring soft key to display the following screen.
Set the wiring system (1P2W, 1P3W, 3P3W, 3P4W, 3P3W(3V3A)).
When you select an element, the wiring systems that you can select are displayed. Select the wiring system
from those displayed.
Wiring System Combination
• If you select 1P3W, 3P3W, 3P4W, or 3P3W(3V3A) for the wiring system, the wiring unit is set with the two
or three elements adjacent to the selected element whose element numbers are larger than the selected
element.
• On models that have four elements installed, up to two wiring units (ΣA and ΣB) are automatically set. The
wiring unit symbols ΣA and ΣB are attached to the element numbers in order, starting with the smallest
number.
Note
• Because the wiring system with the largest element number is automatically determined according to
the settings of the wiring system with the smallest element number, the element with the largest element
number cannot be selected.
• You cannot set the wiring units for larger element numbers before the wiring units for smaller element
numbers.
