Shortest-path traverse of rotary axes: M126
Standard behavior
Refer to your machine manual.
The positioning behavior of rotary axes is machine-
dependent.
The default behavior of the control while positioning
rotary axes whose display has been reduced to values
less than 360° is dependent on the
shortestDistance
machine parameter (no. 300401). This machine parameter defines
whether the control should consider the difference between
nominal and actual positions, or whether it should always choose
the shortest path to the programmed position (even without
M126). Examples:
Actual position
Nominal position
Traverse
350°
10°
–340°
10°
340°
+330°
Behavior with M126
With
M126
, the control will move a rotary axis, whose display is
reduced to values less than 360°, on the shortest path of traverse.
Examples:
Actual position
Nominal position
Traverse
350°
10°
+20°
10°
340°
–30°
Effect
M126
becomes effective at the start of the block.
To cancel
M126
, enter
M127
. At the end of program,
M126
is
automatically canceled.
