NOTE
Carefully issue a command to shift the polar coordinate
interpolation coordinate system with this parameter disabled
because the command is recognized as a move command
and the machine operates.
5460 Axis (linear axis) specification for polar coordinate interpolation
5461 Axis (rotary axis) specification for polar coordinate interpolarion
[Data type] Byte
[Valid data range] 1, 2, 3, ... control axes count
These parameters set control axis numbers of linear and rotary axes to
execute polar interpolation.
5462 Maximum cutting feedrate during polar coordinate interpolation
[Data type] 2–word

Millimeter machine 1 mm/min 0, 6 to 240000 0, 6 to 100000
Inch machine 0.1 inch/min 0, 6 to 96000 0, 6 to 48000
Rotation axis 1 deg/min 0, 6 to 240000 0, 6 to 100000
This parameter sets the upper limit of the cutting feedrate that is effective
during polar coordinate interpolation. If a feedrate greater than the
maximum feedrate is specified during polar coordinate interpolation, it is
clamped to the feedrate specified by the parameter. When the setting is 0,
the feedrate during polar coordinate interpolation is clamped to the
maximum cutting feedrate usually specified with parameter 1422.
