5.AUTOMATIC OPERATION B-63783EN-1/01
- 524 -
Signal
Block cancel signal BCAN <G157#6>
[Classification] Input signal
[Function] Cancels the current block in progress.
[Operation] When the signal goes to 1 during automatic operation, the block being
executed is cancelled, and the automatic operation stops.
Block cancel acknowledgement signal MBCAN <F157#4>
[Classification] Output signal
[Function] Posts notification that the block cancel signal has been received.
[Output condition] When block cancel signal BCAN goes to 1 during automatic operation
and when the cancel operation starts, this acknowledgement signal also
goes to 1. When the block cancel operation terminates, when the
automatic operation stops, and when block cancel signal BCAN goes to
0, this acknowledgement signal goes to 0.

If the block cancel signal is set to 1 while the miscellaneous function,
spindle function, tool function, or second miscellaneous function is
being executed, the corresponding strobe signal (MF, SF, TF, or BF)
goes to 0. If the high-speed M/S/T/B interface is used, the status of the
strobe signal does not change. The corresponding completion signal
(MFIN, SFIN, TFIN, or BFIN) should be set to the same logic level as
the strobe signal.
