5. TOOL FUNCTION (T FUNCTION)
95
(5)A tool in a multiple tool holder to another tool in the same multiple tool
holder
When the T command for a tool in a multiple–tool holder is issued
after another tool in the same tool holder has been selected, the
necessary T code and the corresponding TF signal are output. The
machine then returns the FIN signal. (If necessary, move the tool
holder according to the T command, and return the FIN signal after
completion.)
When the FIN signal is returned, the CNC moves the C axis as
specified by the last two digits of the T code and starts indexing the
required tool. When indexing the tool starts, the tool indexing signal,
CMOK, is switched to 1. When the tool has been indexed, the MIE
signal is switched to 1 and the CMOK signal is switched to 0. This
completes indexing the tool.
The T command
is read.

D It is necessary to combine the C–axis control option to use
multiple–tool control
D When using multiple–tool control, do not issue a C–axis command.
D When using multiple–tool control, set parameter No. 3032 to 3 or 4.
To index a tool in a multiple–tool holder, specify a T code consisting
of at least three digits. To index a regular tool, specify a T code
consisting of two digits or less.
D The MIE signal, which indicates that indexing the tool in a
multiple–tool holder is complete, is switched to 1 when a tool has been
indexed. However, switching the MIE signal to 1 is synchronized with
the start of C–axis deceleration.
D When using multiple–tool control, set parameter CRM (No. 16362#5)
to 0.
