If the mode is changed during chopping, chopping does not stop. In
manual mode, the chopping axis cannot be moved manually. It can,
however, be moved manually by means of the manual interrupt.
When a reset is performed during chopping, the tool immediately moves
to point R, after which chopping mode is canceled.
If an emergency stop or servo alarm occurs during chopping, mode is
canceled, and the tool stops immediately.
The following table lists the operations and commands that can be used
to stop chopping, the positions at which chopping stops, and the operation
performed after chopping stops:
