A traversing movement is completed when the axis has reached the setpoint position + - the

The fine exact stop limits operate for:
• G09/G60
• Block before G33 and G63
Note
In continuous-path operation (G64), neither the coarse nor the fine exact stop tolerance range
is approached (exception: G00).
Actual values are marked with < > in the machine display to indicate that an axis is not in
position.
Example: 840C screen (X axis not in position, Z axis in position)
