7-4-11 Precautions on the Stopover Function

Example
The following occurs with circular interpolation.
The D code is output when the axis has moved –70 mm on the X axis during
circular interpolation as shown in the following figure.
Y axis
Heed the following precautions when using the Stopover function.
• Normally, the Stopover function is not valid if the specified distance moved
is the same as the next demand position.
N0100 G00 X100
N0110 G00 X200
• The Stopover function may not be valid in operations where the axis
moves back and forth between two points in Pass Mode.
Outputs D code 100 at this point.
Starting point
M500/X100 If the specified distance is 100 mm
which is the same as the distance
from X100 to X200, then the Stop-
over function will not be valid after
the axis has moved to demand posi-
tion X200.
M code 500 will be output if the travel
distance exceeds 100 mm (large X-
axis overshoot) before the demand
position X200 is obtained.
