Sys.CK3WConfigErr
There is an error in the CK3W hardware configuration.
0 to 7
Checks that there are no errors in the configurations of the connected CK3W Unit and
End Cover.
0: No hardware configuration error
1: No End Cover
2: Five or more CK3W Units are installed to the CPU Rack or Expansion Rack, except
for the Expansion Master Unit and Expansion Slave Unit.
3: Reserve
4: Three or more Axis Interface Units are installed to the CPU Rack or Expansion Rack.
5: The Expansion Master Unit is not installed adjacent to the right side of the CPU Unit.
6: Reserve
7: Address switches overlap.
When an error occurs, the Unit number counted from the CPU Unit at which the error
was detected is written to the Sys.CK3WConfigCount register. However, the CK3W-
EXS02 (Expansion Slave Unit) is excluded from the count.
If Sys.CK3WConfigCount is "0", it shows that an error was detected in the CPU Unit. If
Sys.CK3WConfigCount is "1", it shows that an error was detected in the Unit installed
next to the CPU Unit.
When power is turned ON or the Controller is reset.
Cycle the power supply, or issue reset command ($$$)
Operation continues

Correction
Attach an End Cover
Reduce the number of
CK3W-AX Units connected
to two or less.
Set a unique address to
prevent duplication of the
address switch value.
Reduce the number of
CK3W Units connected to
four or less in each rack.
Install the Expansion Mas-
ter Unit adjacent to the right
side of the CPU Unit.
If there is conductive mate-
rial nearby, blow air through
the Unit.
