B–63443EN/02
PMC INTERFACE
188
When an M, S, or T function is commanded in the MEM or MDI mode,
and axial movement ends but the FIN signal for the M, S, or T command
is not issued, the distribution end signal DEN turns to “1”. The DEN turns
to “1” until the FIN signal for the M, S, or T command is issued even in
the block in which no axial movement exists. When the operation ends
by arrival of the FIN signal for the M, S, or T function, the DEN signal
turns to “0”. Use this signal to discriminate between simultaneous
execution of an auxiliary (M, S, or T) function with the start of movement,
and execution after the end of movement when an auxiliary function and
move command are specified in the same block.
Fig. 15.2 shows the time chart of this signal.

Fig.15.2 Distribution End Signal and Other Signals
If this signal is turned ”1”, binary code signals and M read command
signal is not output, even when executing M, S, or T function block.
NOTE
1 Internal processing of M98 and M99 is done, regardless of
the AFL signal.
2 M00, M01, M02, and M30 are output even if the AFL signal
is “1”.
3 An analog voltage for the spindle is output even when the
AFL signal is ”1.”
