Set CNC Move Protection dialog box

CNC/SETPROTECTION, movesProtected

This command sets the state of moves. By default protected moves are safe. This means unexpected probe hits will terminate part program execution. Because of the potential danger of unprotected moves, a second safety lock is in place in the definition of machines in PC-DMIS CNC Server.

movesProtected parameter can be either "Yes" or "No". If you set this to "Yes", then positional moves in the CNC program will be protected and any unexpected probe hits will be recognized by the controller and execution will be suspended or terminated, depending on how the CNC control deals with alarm conditions. Some controls will have some error recovery abilities, some will not. If you set this to "No", moves will be unprotected, but only if the CNC machine definition allows unprotected moves. This double check is in place, because unprotected moves will not stop prematurely resulting in damage to the probe.

This menu option and Edit window command are not available for PC-DMIS NCI.
