Example of program (Local coordinate designation during program coordinate rotation)
(1) When "#19003 PRG coord rot type" is "0", it is on the coordinate system after coordinates
rotation that the commanded position is set as the local coordinate zero point.
(2) When "#19003 PRG coord rot type" is "1", it is on the coordinate system before coordinates
rotation that the commanded position is set as the local coordinate zero point. Then the
coordinates system is rotated.

The workpiece coordinate zero point after rotation is considered as
(X,Y)=(0,0). The position after shifted by 10 each in the X and Y
direction is set as the local coordinate zero point.
- The direction of the shift is not the direction of X' and Y'.
(X",Y")=(20,30)
Start point:
(X",Y")=(10,30)

The commanded axis moves on the rotation coordinate system.
- Axis without movement command does not move.
