Specify the maximum cutting feedrate.
A feedrate in the tangential direction is clamped in cutting feed so that it
does not exceed the feedrate specified in this parameter.
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] Two–word
Valid data range
y
IS-B IS-C
Millimeter machine 1 mm/min 0, 6 – 240000 0, 6 – 100000
Inch machine 0.1 inch/min 0, 6 – 96000 0, 6 – 48000

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.
No. Message Description
145 ILLEGAL CONDITIONS
IN POLAR COORDINATE
INTERPOLATION
The conditions are incorrect when the polar
coordinate interpolation starts or it is can-
celed.
1) In modes other than G40, G12.1/G13.1
was specified.
2) An error is found in the plane selection.
Parameters No. 5460 and No. 5461 are
incorrectly specified.
Modify the value of program or parameter.
