10.5.3 Positioning mode, M19, M19 through several revolutions
Examples
Example 1
0°
Last M19 position: 0°
Actual position: 270°
Specified travel: +180°
This means that the spindle has moved 90° from the last M19 position in the opposite
direction to the specified direction, so the total is:
Distance to be traversed: +270°
Example 2
0°
last M19 position: 90°
Actual position: 0°
Specified travel: –180°
The spindle has thus moved 90° from the last M19 position in the specified
direction, so the total is
Distance to be traversed: –90°
