8. AUXILIARY FUNCTION
403
(6)If the completion signal remains set to 1 for longer than period TFIN,
specified in parameter No. 3011 (standard value: 16 msec), the CNC
sets the strobe signal to 0 and reports that the completion signal has
been received.
(7)When the strobe signal is set to 0, set the completion signal to 0 in the
PMC.
(8)When the completion signal is set to 0, the CNC sets all code signals
to 0 and completes all sequences of the miscellaneous function.(*2)
(9)Once all other commands in the same block have been completed, the
CNC executes the next block.
*1 When the tool function is executed, the programmed tool number is
sent as the code signal (T series).
*2 When the spindle–speed function, tool function, or secondary
auxiliary function is executed, the code signal is maintained until a
new code for the corresponding function is specified.
