When a circular interpolation command (G02, G03) is executed, the
tolerance for the radius between the start point and the end point is set. If
the difference of radii between the start point and the end point exceeds the
tolerance set here, a P/S alarm No. 20 is informed.
NOTE
When the set value is 0, the difference of radii is not
checked.
Number Message Description
011 NO FEEDRATE
COMMANDED
Cutting feedrate was not commanded
or the feedrate was inadequate.
Modify the program.
020 OVER TOLERANCE OF
RADIUS
In circular interpolation (G02 or G03),
difference of the distance between the
start point and the center of an arc
and that between the end point and
the center of the arc exceeded the
value specified in parameter No.
3410.
021 ILLEGAL PLANE AXIS
COMMANDED
An axis not included in the selected
plane (by using G17, G18, G19) was
commanded in circular interpolation.
Modify the program.
