Types of warnings
A warning occurs during OPR control, positioning control or JOG operation.
If a warning occurs, operation is continued. Also, if a warning occurs, "Md. 4 Axis
operation status" remains unchanged.
Warning storage
If a warning occurs, the axis warning occurrence signal turns ON and the warning
code corresponding to the warning definition is stored into "Md. 6 Axis warning
code".
Also, the bit of " Md. 11 Warning status" corresponding to the warning occurrence
axis turns ON.

axes).
•
The axis warning occurrence signal (X2) is turned OFF ("1" is set in Cd. 1 of all
axes).
•
"Md. 4 Axis operation status" changes from "Error" to "Standby".
•
"Md. 5 Axis error code" is cleared to zero.
•
"Md. 6 Axis warning code" is cleared to zero.
[4] Confirming the error and warning definitions
The error and warning definitions can be confirmed in "Md. 5 Axis error code" and
"Md. 6 Axis warning code". To confirm them, GX Developer or GX Configurator-PT
is needed. For details, refer to "Section 13.5 Confirming the error definitions using
system monitor of GX Developer" or "CHAPTER 6 UTILITY PACKAGE (GX
