What does Mazak alarm 511 mean?

Mazak alarm 511 is "PROGRAM DATA NOT SAME (WNo., UNo., SNo.)". Comparison between the cassette tape or floppy disk contents and the NC data has shown several disparities. Error type: Operation — wrong key or incorrect operation. Machine state: Operation continued — machine still running.

How do I fix and clear Mazak alarm 511?

1. After correcting the disparities within the machining program, make the comparison once again. 2. If the disparities exist in data other than machining program data, locate those disparities on each display. Note : This alarm message may be displayed if data is saved prior to automatic operation and then subjected to comparison with that after automatic operation. This is because execution of automatic operation may cause automatic data overriding. Clearing procedure: Tap alarm clear button.
