(3)A tool in a multiple–tool holder to a regular tool
If the C axis is not positioned at the reference position when the T
command for selecting a regular tool is issued after a tool in a multiple
tool holder is selected, the C axis automatically returns to the reference
position. Because the tool in a multiple tool holder is moved with this
command, the CMOK signal is switched to 1 and the MIE signal is
switched to 0. When the C axis has returned to the reference position,
the CMOK signal is switched to 0.
Then, the necessary T code and the corresponding TF signal are
output. The machine returns the FIN signal as soon as the tool has been
indexed, as specified by the T code. This completes indexing the tool.
