Pass Mode Limitations
with Linear Interpolation,
Circular Interpolation, and
Traverse Operations
Linear interpolation, circular interpolation, and traverse operations are inter-
polation commands that can be specified for three operating modes. When
these interpolation commands are continuously executed in Pass Mode, there
are cases where pass operations cannot be performed (depending on the
combination of the immediately preceding operation and the present opera-
tion). These cases are shown in the following table.
The preceding and present operations for the table shown below are as fol-
lows:
Preceding operation:
N010 G01 X1000 Y100 F200
Present operation:
N020 G01 Y2000 Y-100 F300
Pass:
Indicates normal Pass Mode operations. Positioning is executed with
pass operations from the preceding operation to the present opera-
tion.
Stop:
Indicates normal Stop Mode operations. The present operation is
executed after the positioning is completed for the preceding opera-
tion.
Note
1.
“Different axes” indicates that the axes that are operated are changed, as
when four axes are used for one task and linear interpolation is executed
for the X and Y axes followed by traverse operation for the Z and U axes.
2.
This indicates cases such as executing ZU-plane circular interpolation af-
ter XY-plane circular interpolation.
3.
This indicates cases such as executing traverse operations after circular
interpolation, or circular interpolation after traverse operations.
4.
The operating mode for the traverse operation will differ according to the
following circumstances.
If the rotating axes are operated in opposite directions, the preceding
traverse operation will be performed in Stop Mode.
If the rotating axes are operated in the same direction, positioning will
be executed in Pass Mode.
5.
When four axes are used for one task, the traverse operation is executed
first for the X and Y axes and then for the Z and U axes.
