RESTART OPERATION NOT ALLOWED (WNo., NNo., BNo.)

What it means

1. Restarting from the block containing the G06.2/G43.4 mode data has been attempted. 2. During the control of cross machining, restarting the program containing another cross machining command has been attempted in the corresponding command sequence or subsequent. 3. During the INTELLIGENT SAFETY SHIELD for automatic operation is valid, EIA modal restarting from the block preceded by the M660 block has been attempted. 4. When 1 is set for bit 3 of parameter F93 or bit 7 of parameter F94 with a turning tool mounted, restarting has been attempted from the following block. A block in the G68 mode A block after G68 mode cancellation before execution of the X-/Z-axis positioning in the absolute data command 5. Operation was restarted from a block specified in the orbit machining mode. 6. Operation was restarted from a block between G124 and G125. 7. Operation was restarted from a block specified in the cutting point command mode.

What to do
  1. 11.
  2. 2Restart from a block not containing G06.2/G43.4 mode data.
  3. 32.
  4. 4Modify the program so that the control of cross machining is canceled before another cross machining command is executed.
  5. 53.
  6. 6Cancel the INTELLIGENT SAFETY SHIELD for automatic operation and execute EIA modal restarting search.
  7. 74.
  8. 8Mount a milling tool and restart the program again or set 1 for bit 6 of parameter SU156.
  9. 9However, when 1 is set for bit 6 of parameter SU156, the return to the restarting position is not conducted.
  10. 105.
  11. 11Restart the operation from a block specified in other than the orbit machining mode.
  12. 126.
  13. 13Restart the operation from a block outside the range between G124 and G125.
  14. 147.
  15. 15Restart the operation from a block specified in other than the cutting point command mode.
