B–62073E–1/042. INTERFACE BETWEEN CNC AND PMC–NA OR NB
– 172 –
NOTE 1 Whether to use the conventional system or high–speed system for strobe signal and
completion signal handling can be specified by parameter setting.
NOTE 2 The strobe signals MF, SF, TF, and BF go low when the machine is turned on.
NOTE 3 When the control unit is reset, MF, SF, TF, and BF go low.
NOTE 4 This function cannot be used for the completion signals FFIN and FIN for the canned cycle
spindle stop command signal (SSP) and spindle reverse rotation command signal (SSV); the
conventional signal transfer system is used.
This function cannot be used for the completion signal FIN for the external operation signal (EF)
output by G81 to specify external operation; the conventional signal transfer system is used.
(a) Auxiliary function completion signal (MFIN [#1, #2])
[Classification]
Input signal
[Function] Reports that the execution of a miscellaneous function using the high–speed M/S/T/B inter-
face is completed.
[Operation] For the operation and procedure of the control unit when this signal goes high and low, see
the description of “Signal transfer procedure
” above.
(b) Spindle function completion signal (SFIN [#1, #2])
[Classification]
Input signal
[Function] Reports that the execution of a spindle function using the high–speed M/S/T/B interface is
completed.
[Operation] For the operation and procedure of the control unit when this signal goes high and low, see
the description of “Signal transfer procedure
” above.
(c) Tool function completion signal (TFIN [#1, #2])
[Classification]
Input signal
[Function] Reports that the execution of a tool function using the high–speed M/S/T/B interface is com-
pleted.
[Operation] For the operation and procedure of the control unit when this signal goes high and low, see
the description of “Signal transfer procedure
” above.
(d) 2nd auxiliary function completion signal (BFIN [#1, #2])
[Classification]
Input signal
[Function] Reports that the execution of a second auxiliary function using the high–speed M/S/T/B inter-
face is completed.
[Operation] For the operation and procedure of the control unit when this signal goes high and low, see
the description of “Signal transfer procedure
” above.
