During normal operation, the digital display shows the current position (in millimeters

display mode (see Section 6.3.4. for more details), so the position displayed will
always be a positive number between 0 and 360 degrees. If set to Total Angle in the
settings panel, the LED display will still show the equivalent 0 to 360° value but the
GUI screen will show the total rotation.

see Section 4.4. The various operating modes are described in Section 4.3.1. to
Section 4.3.3.
