ATOL
Note
CTOL and OTOL have priority over ATOL.
General conditions
Scaling frames
Scaling frames affect programmed tolerances in the same way as axis positions; in other
words, the relative tolerance remains the same.

8.8 Programmable contour/orientation tolerance (CTOL, OTOL,
Command for programming an axis-specific tolerance
ATOL is valid for:
• All compressor functions
• ORISON orientation smoothing
• All rounding types except G641, G644, OSD
Name of the axis for which an axis tolerance is to be programmed
<axis>:
The value for the axis tolerance will be specified as a length or an
<value>:
angle dependent on the axis type (linear or rotary axis).
Type: REAL
Unit: for linear axes:
for rotary axes:
