Remedy
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller. Save the CMOS.BIN before
replace controller to be safe.

Set the number of application file "*.OUT" to be within the defined value. (Delete
unnecessary files from the MotoPlus menu of the maintenance mode.)
Memory to work MotoPlus application is insufficient under the combination of
current system configuration and its optional function. IIf the alarm occurs
again, save the CMOS.BIN in maintenance mode, and then contact your
YASKAWA representative about occurrence status (operating procedure).
(1)Turn the power OFF then back ON.
(2)If the alarm occurs again, replace controller and load the MotoPlus
application which was loaded to the previous controller.
Check that if the object file name is too long or inappropriate letters are used.
