Axes and coordinate systems
Positioning-only rotary axis
It cannot interpolate with linear axes. Movement always in G00, and they do not admit tool radius
compensation (G41, G42).
• Absolute coordinate programming (G90).
Always positive and in the shortest direction. End coordinate between 0 and 359.9999.
• Incremental coordinate programming (G91).
The sign indicates the turning direction. If the programmed movement exceeds 360º, the axis
will turn more than once before positioning at the desired point.
Rotary Hirth axis
It is a positioning-only axis which can take decimal coordinates.
More than one Hirth axis may be used, but they can only move one at a time.
Positioning-only rotary axis
AXISTYPE=3
LIMIT+ = 8000
LIMIT- =-8000
ROLLOVER=YES It counts between 0º and 360º.
G90 does not admit negative values. Always via the
shortest path.
G91The sign indicates the turning direction.
ROLLOVER=NO It counts between 7999.9999º and -7999.9999º.
G90 and G91 as linear axis.
LIMIT+ =0
LIMIT- =0
ROLLOVER=YES It counts between 0º and 360º.
G90 does not admit negative values. Always via the
shortest path.
G91The sign indicates the turning direction.
ROLLOVER=NO There are 2 loops, one between 0º and 360º and the other
between 0º and -360º It is possible to switch from one to
the other.
G90 and G91 as linear axis.
LIMIT+ =350
LIMIT- =10
ROLLOVER=YES/NO It can only move between 10º and 350º.
With G90 and G91 like when LIMIT+=8000. An error
message is issued if the target position is beyond the limits.
Rotary Hirth axis
AXISTYPE=4
LIMIT+ = 8000
LIMIT- =-8000
ROLLOVER=YES It counts between 0º and 360º.
G90 does not admit negative values.
G91The sign indicates the turning direction.
ROLLOVER=NO It counts between 7999.9999º and -7999.9999º.
G90 and G91 as linear axis.
LIMIT+ =0
