Detailed description
(1) G43.1 and G44.1 are modal G codes.
(2) The spindle control mode entered when the power is turned ON or reset depends on the
parameter setting.
Designate the spindle No. to be selected in G43.1 modal with the parameter (basic
specifications parameter "#1199 Sselect").
This parameter is provided for every part system to set as follows.
#
1199
21049 SPname
Reset the NC after changing "#1199 Sselect " and "#21049 SPname" parameters. It is no use
to turn the power OFF once and ON again.
(3) As for C6 L-type, T-type, C64 T-type and C64T T-type, there are following restrictions;
· A program error (P34) will occur if G44.1 command is issued.
· No data can be set to "#1199 Sselect". "0" is set when the NC power is turned ON.
· Only one spindle than is selected with "#21049 SPname" can be commanded as "S ∗∗∗∗∗ "
in each part system.
· A program error (P33) will occur if the "S0= ∗∗∗∗∗ " command is issued.
(4) If the S command is issued in the same as the spindle selection commands (G43.1, and
G44.1), which spindle the S command is valid for depends on the order that G43.1, G44.1,
and S command are issued.
When S command precedes the G codes, it follows the G43.1 / G44.1 mode before S
command is issued.
When G codes precede, it follows the G43.1 / G44.1 mode issued in the same block.
(5) G43.1 and G44.1 commands can be issued from every part system.
Selected spindle (nth spindle) control mode ON
