NOTE
1 Check of the tool path between blocks is executed for forbidden area defined by
stored stroke limit of plane selection axes and plane non-selection axis.
Therefore, even if the axis other than plane selection axes and plane
non-selection axis exceed the forbidden area defined by stored stroke limit in the
tool path between blocks, the alarm is not generated by check of the tool path
between blocks. (However, because stored stroke check of normal is effective,
the alarm is generated when approaching the forbidden area defined by stored
stroke limit during moving the axis.)
2 When the forbidden area is defined by inside of stored stroke limit, the alarm is
generated if all axes to which stored stroke check is effective enter the forbidden
area. However, in check of the tool path between blocks, the alarm is generated if
plane selection axes and plane non-selection axis enters the forbidden area.
Limitation
Limitation of Stroke limit check before move
Limitation of Stroke limit check before move is effective for check of the tool path between blocks.
Non-linear type positioning
Check of the tool path between blocks is executed for the straight-line that connect the start position and
end position of the block even if Positioning (G00), High-speed reference position return (G28, G30), or
Selecting a machine coordinate system (G53) is move by non-linear type. Therefore, check of the tool
path between blocks might not be able to be executed correctly, depending on the command.
Circular interpolation that is imperfect circle
When Circular interpolation that is imperfect circle is specified, check of the tool path between blocks is
executed for the base circle. Therefore, check of the tool path between blocks might not be able to be
executed correctly, depending on the shape of Circular interpolation.
Machine lock
For the axis which is Machine lock state when starting the block, check of the tool path between blocks is
not executed.
Stored stroke check 2 off (G23)
When Stored stroke check 2 is invalid (G23 mode), check of the tool path between blocks for the
forbidden area defined by Stored stroke limit 2 is not executed.
Arbitrary angular axis control
Stored stroke limit can be checked in Cartesian coordinate system by setting bit 0 (AOT), bit 1 (AO2) or
bit 2 (AO3) of parameter No.8201 in Arbitrary angular axis control. By setting of checking stored stroke
limit in Cartesian coordinate system, check of the tool path between blocks is effective. Check of the tool
path between blocks by this stored stroke limit is not executed if angular axis or perpendicular axis to
which stored stroke limit is checked by slanted coordinate system is set to plane selection axes or plane
non-selection axis.
