[Data type] Word

Metric input 0.001 0.0001 mm
Inch input 0.0001 0.00001 inch
[Valid data range] 0 to 32767
These parameters set the maximum and minimum tolerances used to
determine whether to apply smooth interpolation. If the tolerance
specified in a block is larger or smaller than these settings, smooth
interpolation is not applied to that block.
Usually, set about one–tenth of the setting for the maximum tolerance
(No. 8491) for the minimum tolerance (No. 8492).
Reference: Tolerance means the distance between curve C which
smoothly connects the specified points and line L.

Line L
Tolerance
A circle indicates a specified point.
NOTE
If a value of 0 is set for the minimum tolerance (No. 8492),
the minimum tolerance is assumed to be one–tenth of the
maximum tolerance (No. 8491).
If a negative value is set for the minimum tolerance (No. 8492),
the minimum tolerance (No. 8492) is assumed to be 0.
