•
If a feed value is not programmed in the G75 NC-block, traversing is
performed at the speed entered in the axis parameter ‘Max. Feed to
Positive Stop’.
•
If the programmed final axis position value is reached, the error mes-
sage:
„Positive Stop not within programmed move (@-axis)”
is issued.
•
If the stop yields and wanders during operation, or if the axis slide is
forced out of position by a strong opposing force, the axis position is
updated. If this causes the initial position for the NC-block not to be
reached or the final position for the NC-block to be exceeded, the error
message:
„Positive Stop not within programmed move (@-axis)”
is issued.
•
The dimensional information in a G75 NC-block can be entered in ab-
solute mode (G90) or incremental mode (G91).
•
If a number of axes are programmed in a G75 NC-block, the axis
movement of the axes is not performed with interpolation.
Note:
The parameters ‘Reduced Torque at Positive Stop’ and ‘Max.
Feed to Positive Stop’ are set by the machine builder in the
axis parameters.
