13.3 EXTERNAL MOTION FUNCTION (G81)
Upon completion of positioning in each block in the program, an
external operation function signal can be output to allow the machine to
perform specific operation.
Concerning this operation, refer to the manual supplied by the machine
IP_ : @Axis move command
L_ : @Number of repeats (if required)
Every time positioning for the IP_ move command is completed, the
CNC sends a external operation function signal to the machine. An
external operation signal is output for each positioning operation until
canceled by G80 or a group 01 G code.
Upon a reset or at power-up, the cancel state based on G80 arises.
- Movement command
In a block which does not contain a move command, the external
operation signal is not sent.
- Relationship with canned cycle G81
G81 can also be used for a drilling canned cycle. Whether G81 is to be
used for an external motion function or for a drilling canned cycle is
specified with EXC, bit 5 of parameter No.6200.
