14.28 Applying the Rotary Axis Configuration Parameter
On a multi-tasking machine, one rotary tool may be shared with multiple part systems. In this case, arbitrary axis exchange
control and mixed control which an arbitrary axis between part systems can be exchanged freely are used.
When operating a specific function (*1) in combination with arbitrary axis exchange (G140) command and mixed control I/ II
commands, the rotary axis configuration parameter need to be set with the 2nd axis name. Set the parameter "#1450
5axis_Spec/bit0" (axis name setting method of rotary axis configuration parameter) to "1", and set the axis configuration with
the second axis name (e.g. A1, B2) to operate these functions in the rotary axis configuration parameter (from #7900). When
"#1450 5axis_Spec/bit0" is set to "0" (Set by axis name), an operation error or a program error occurs if these functions are
performed after the arbitrary axis exchange.
You can specify the configurations up to the number of valid part systems (max. 4) for the rotary axis configuration parameter.
When multiple configurations are specified, these functions can be performed with different axis configurations.
(*1) This indicates the following functions:
 Inclined surface machining command
 Simple Inclined Surface Machining Command
 Rotation center error compensation
 Tool center point control (Can be combined with arbitrary axis exchange only)
 3-dimensional manual feed (Can be combined with arbitrary axis exchange only)
By applying the rotary axis configuration parameter whose configuration is that all the existing axes in the part system have
been set, the target function with the axis configuration in the part system after the axes exchange is available.
