[Function] When an auxiliary function (CDxX7 to CDxX0: 08h) is specified from
the PMC, the CNC sends auxiliary function code signal DTnX7 to
DTnX0 to auxiliary function BCD code signal AFnX7 to AFnX0, and
waits for auxiliary function completion signal FINnX.
Upon receiving the auxiliary function completion signal FINnX, the
CNC proceeds to the next command block. The timing for sending the
auxiliary function code and auxiliary function read signals and
receiving the auxiliary function completion signal is the same as that
for the auxiliary function (M function) under CNC control. Auxiliary
function selection code signals DTxX15 to DTxX8 specify the
selection number (n number) of an auxiliary function signal to be used.
If the n number is other than 1, 2, and 3, the relevant block is regarded
as being invalid and is terminated.
