A separate allowable feedrate difference can be set for each axis. The
allowable feedrate difference is set for each axis with this parameter.
Among the axes that exeed the specified allowable feedrate difference, the
axis with the greatest ratio of the actual feedrate difference to the
allowable feedrate difference is used as the reference to calculate the
reduced feedrate at the corner.
