AFC In polar coordinate interpolation mode, automatic override operation
and automatic feedrate clamp operation are:
0 : Not performed.
1 : Performed.
NOTE
In polar coordinate interpolation mode, the feedrate
component for a rotational axis increases as the
tool moves closer to the center of a workpiece.
Near the center of a workpiece, the maximum
cutting feedrate (parameter No.5462) may be
exceeded, causing servo alarm No.411 to be
issued. The automatic feedrate override function
and automatic feedrate clamp function
automatically control the feedrate to prevent the
feedrate component on a rotary axis from
exceeding a specified maximum cutting feedrate.
