5. TOOL FUNCTION (T FUNCTION)
89
The content of the number of punches of the tool until at that time which
corresponds to T code instructed when T command is done is outputted
to PMC from CNC.
It is a binary code signal of 32 points.
Correspond to the number of punches and the signal as follows.
Number of punches = 2 Pi (0 to 99999999)
However Pi = 0 when PNi is 0.
Pi = 1 when PNi is 1.

When the T command is done, T code signal is turned to 1 and the number
of punches up to that point corresponding to the T code is outputted.
The content is maintained until a new T command is done.
CAUTION
Signals PN00 to PN31 are 0 until T command is done for the
first time after the power supply is turned on.
[Classification] Output signal
[Function] These signals notify the PMC that the machine coordinate of the T–axis
agrees with the machine zero point. The PMC is thus aware of the special
tool indexing point.
[Output condition] When the machine coordinate of the T–axis becomes the position set in
parameters 16680 to 16695 under T–axis control, the bit signal
corresponding to the parameter is output.
