■ Coordinate diagram for absolute position data calculation
Absolute position data is calculated with the following coordinate diagram.
• Motor rotate direction: When CCW (SYS_05＝0)
• Motor rotation direction: When CW (SYS_05=1)
Coordinate value is the coordinate value output by encoder for each rotation, so it is different from actual command unit
(encoder resolution). The higher-level equipment needs to convert pulse to command unit according to encoder pulse
and encoder resolution.
