5.5.1 Deleting NC Data in Execution Program
If the host computer gives C4 command to AVK3, the NC data in NC program registered in the AVK3 can be
deleted by one block lot.
Deletion of NC data in the execution program ends with sending A2 command from the host computer.
Data details
NC data can be deleted by sending D1 command from the host computer after the A0 command (data
request) has been sent from the AVK3.
If sending NC data deletion from the host computer, the deleted NC data of the next block is sent from the
AVK3 in D1 command.
When the deleted NC data of the next block is returned from the AVK3, the NC data of the other block can
be deleted.
