CAUTION
To use the compensation function, set parameter TDF (No.
16263#2) to 1.
The following tool changes are possible using the multiple–tool system.
(1)A regular tool (not in a multiple–tool holder) to another regular tool
(2)A regular tool to a tool in a multiple tool holder
(3)A tool in a multiple–tool holder to a regular tool
(4)A tool in a multiple–tool holder to a tool in another multiple–tool
holder
(5)A tool in a multiple tool holder to another tool in the same multiple tool
holder
Tool changes (2) to (5) are described below.
(2)A regular tool to a tool in a multiple tool holder
If the C axis is not positioned at the reference position when the T
command to select a tool in the multiple–tool system is issued, the C
axis automatically returns to the reference position.
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 first two digits of the T code.
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 (the completion signal) is switched to 1 and the CMOK signal
is switched to 0. This completes indexing the tool.
