Concerning this operation, refer to the manual supplied by the machine
G81 IP_ ; ( IP_ Axis move command )
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.
No external operation signals are output during execution of a block that
contains neither X nor Y.
G81 can also be used for a drilling canned cycle (II–14.1.4). Whether G81
is to be used for an external motion function or for a drilling canned cycle
is psecified with EXC, bit 1 of parameter No.5101.
D A block without X or Y
