14.28 Applying the Rotary Axis Configuration Parameter
You can check the rotary axis configuration parameters being applied with rotary axis configuration parameter output (R656).
If there are no applying rotary axis configuration parameters, NC notifies "0" on the rotary axis configuration parameter No.
(R656/low-order 8 bits). If the target function is performed under this situation, an operation error or a program error occurs.

Application method of rotary axis configuration parameter
There are following types to apply the rotary axis configuration parameter. You can switch the application methods with
parameter "#1450 5axis_Spec/bit2" (Application of rotary axis configuration parameters).
Specify the "automatic selection method" if the rotary axis configuration parameter, which matches the axis configuration
when executing the target function, can be determined uniquely. Specify the "PLC signal method" if the parameter cannot be
determined uniquely and you want to designate the parameter to apply.
 Automatic selection method ("#1450 5axis_Spec/bit2" is "0")
For the specified rotary axis configuration parameter, the configuration that all the axes in the commanded part system are
specified is searched in the order of own part system, $1, $2 and subsequent part system at the time of following three.
 Power ON
 NC reset
 Arbitrary axis exchange control (G140/G141/G142) command
 Mixed control I/II command
The configuration of the rotary axis configuration parameter matched first will be applied.
