Set the valid maximum feedrate of the polar coordinate interpolation. If the commanded speed is
greater than the value, the speed is limited by the maximum one. When the parameter is set as 0, the
speed in the polar coordinate interpolation is limited by the maximum cutting feedrate (parameter
NO.1422) value.

When the polar coordinate interpolation is set, the percentages of the auto override are allowed
to limit the cutting feedrate of the rotary axis.
Note: When the parameter value is set as 0, it is taken as 90%;
To limit the auto speed override and the auto speed, the parameter AFC (NO.5450#1) is set as 1.

The allowable speed of the rotary axis = Maximum cutting feedrate X override
percentage
In polar coordinate interpolation, the more closely the tool is near to the work piece
center, the bigger the speed vector of the rotary axis is. When it exceeds the allowable speed,
the feedrate automatically multiplies by the override value calculated through the following
formula:
Override = Allowable speed of the rotary axis/the speed vector of the rotary axis X 100%
If the revolving speed after timing the override still exceeds the allowable speed, the feedrate
is limited in the allowable maximum cutting feedrate (auto speed limit function) .
