The master axis (A-axis) moves before the G43.4 command and, after the G43.4
command, circular interpolation is performed using the G17 (X-Y plane) command
after rotating the C-axis, or the C-axis is rotated during circular interpolation.
→ Alarm (violation of <2>)
(Note that C-axis center is not perpendicular to X-Y plane.)
Example)

After the G43.4 command, the A-axis is moved and circular interpolation is performed
using the G17 command (X-Y plane).
→ Alarm (violation of <2>)

G19 (Y-Z plane) command is executed
The G43.4 command is executed after moving the A-axis and circular interpolation is
performed while rotating the A-axis using the G19 (Y-Z plane) command.
→ This case corresponds to <1> and allows circular interpolation.
