Alarm/Error codes X axis: Word S+1
15
X: (S+1)
Y: (S+9)
Note The NC113 is provided with the X axis only.
If there are multiple errors or alarms, use the READ ERROR command. The er-
ror code from the NC Support Tool or the contents of words s+1 and s+9 can be
displayed on the Programming Console. If there are no errors or alarms, 0000
will be displayed. If there are any errors or alarms, they will be displayed in code.
The codes will be displayed in order as READ ERROR is executed. (If there is
only one code, however, the display will not change when READ ERROR is
executed.)
X axis: m+1
The word for the Y axis is m+5. (NC211 only)
The following diagram shows an example in which first the alarm code 1201 and
then the error code 5000 are displayed.
The error or alarm code (word s+1) is refreshed immediately after the READ ER-
ROR command bit is turned ON. The Busy Flag does not turn ON.
Display will not change be-
cause only one alarm code has
been generated.

First alarm code
Y axis: Word S+9

Error code (or alarm code)
Generally, a new error (or alarm) outputs a single
error code. When the READ ERROR command bit
(word n+1, bit 05) turns ON, multiple error or alarm
codes (or alarm codes) can be read sequentially.
