Caution: Unit depends on system settings. Using 'Metric' unit is 1e-1 µm. Using 'English' unit is 1e-5 inch.

Attention:
The command 'R' was designed for 200 mm wafer and might not work with 300 mm wafer
In future, one could use the command ur11401 und ur11402 to read x and y position. The 'ur' command is used
to read parameter values. However, the coordinate system of ur11401 und ur11402 is different with respect to
the 'R' command

Returns:
int: x coordinate in µm
int: y coordinate in µm
