Restoring axis configurations and axis couplings

Complex multi-channel machines which use axis exchange operations and synchronous axes (synchronous mode) for machining are aborted by an NC reset if an error occurs. The NC channels are then reinitialised and the channel configurations valid at the time of the abort are lost. To permit clearance of tool axes, it is necessary to restore the axis configuration which was active at the time of abort and comprising the axes found in the channel and the selected axis couplings. This is implemented by the NC commands described below.
