15.1 Arbitrary Axis Exchange Control

15.1 Arbitrary Axis Exchange Control
An arbitrary axis can be exchanged freely across part systems in the multiple part systems.
The machining can be freer in the multiple part systems by exchanging an axis which can be commanded for machining
programs in each part system.
This makes it possible to perform operations which are not possible with regular axis configurations: for instance, tools which
are provided only on the 1st part system can be used for machining on the 2nd part system.
This function cannot be used with the mixed control (cross axis control).
Refer to "Programming Manual" for the details of the function.

 Command format
Arbitrary axis exchange command
Commands the arbitrary axis exchange by G140.
G140 command address = axis address command address = axis address...;
Command ad- : Designate the command address used in commands such as the movement command with one al-
dress phabetical character set to the parameter after the arbitrary axis exchange command (G140).
Axis address : Designate the axis name for arbitrary axis exchange with two alphanumeric characters set to the pa-
rameter.
Arbitrary axis exchange return command
Returns the control right of the axis, exchanged by the previous arbitrary axis exchange command (G140) in the commanded
part system, to the state before the axis exchange.
G141 ;
Reference axis arrange return command
Returns the control right of the axis, exchanged by the arbitrary axis exchange command (G140) in the commanded part
system, to the power-on state.
G142 ;
Note
(1) For G code list 6 and 7, replace G140, G141 and G142 with G165, G166 and G167.
