After the G43.4 command, the Z-X plane is selected using the G18 command and
circular interpolation is commanded after rotating the C-axis.
→ Alarm (violation of <2>)
The same is also true when the G19 command is used.

• In the case of a table rotation type machine
Descriptions are based on the following machine configuration.
A table rotation type machine can be considered equivalent to a mixed type machine
if one of its two table rotation axes does not move.

When the G17 (X-Y plane) command is executed
The master axis (A-axis) moves before the G43.4 command and, after the G43.4
command, circular interpolation is performed without rotating the A- or C-axis
(including those cases where the C-axis moves before the G43.4 command).
→ This case corresponds to <2> and allows circular interpolation.
