and status
The user cannot correct these
errors. Please replace the ap-
propriate part.
Perform a JOG operation to
move the workpiece away from
the CW or CCW limit switch, and
then enter ERST (error reset).
This erases the stored origin, so
you must re-establish the origin.
Transfer ERST from the PC, or
press the ERST key on the
Teaching Box.
