Error Flag
The Error Flag turns ON when an error occurs.
Check the Error Type Data and Error Code to find the type of error.
If more than one error occurs, the error type data and error code indicate the
error detected first. The order of priority for detecting the system, task, and
axis errors is as follows: System, task 1, task 2, task 3, task 4, X axis, Y axis,
Z axis, and U axis.
This flag is turned OFF when the Error Reset Bit is turned ON.
This flag is turned ON again when another error is detected.
When an error occurs, the Error Flag will be turned ON immediately for sys-
tem errors in Manual Mode and for the following errors:
The Error Flag will turn ON at the completion of a deceleration stop for other
errors.
