Limitation
- Cases in which linear interpolation is performed
- If the start point, mid-point, and end-point are on the same line, linear interpolation is
performed.
- If the start point coincides with the mid-point, the mid-point coincides with the end point,
or the end point coincides with the start point, linear interpolation is performed up to the
end point.
- If the start point, mid-point, and end-point are on the same line and the end point lies
between the start point and the mid-point, the tool first moves with linear interpolation from
the start point to the mid-point, then returns from the mid-point to the end point with linear
interpolation. Thus, the tool always passes through the specified point.
- Whole circles
A whole circle (360 arc) cannot be specified. (This corresponds to the case in which linear
interpolation is performed, as described earlier.)
- Compensation functions
Before using this function, cancel the compensation functions of group 07, such as cutter
radius compensation.
- Manual absolute
While this function is in use, manual intervention is not possible with the manual absolute
switch set to the ON position. If intervention is performed, alarm PS5433 is issued when
operation restarts.
- Background graphic
This function cannot be used with background graphic drawing.
- Limitation of Functions
In the mode for this function, the following functions can be used, but the condition of each
function cannot be changed
- Inch/metric conversion
The alarm is issued when the condition is changed by G20 or G21 command.
- Mirror image
The condition of DI signal cannot be changed.

Format The command format is as follows: G02.4 XX1 YY1 ZZ1 αα1=β β1 ; First block (mid-point of the arc) XX1 YY1 ZZ1 αα1=β β1 ; Second block (end

During MDI operation, alarm PS5432 is also issued if a cycle start is applied with only the mid-point specified. - Movement along axes other than th
