8.14.5.1 Unlimited/limited/modulo traversing range
Motion profiles can only be described in close connection with the machine parameters. In
particular, the nature of the traversing range and, in some cases, the cycle have a significant
influence on the shape of the motion profile.
In principle, the different traversing ranges can be combined in any way in a motion profile but not
all combinations are useful.
Unlimited traversing range
• The drive can rotate continuously in one direction.
• The tool to be driven is not divided (example: feed control tape).
[8-16] Examples of an unlimited traversing range
• Typical curves for the unlimited traversing range:
[8-17] Example: Feed profiles

Note!
If you create a motion profile for the drive axis with the »Cam editor«, use the "Modulo"
traversing range for the x axis in the »Cam editor«, as otherwise the master value/
master angle is not closed by a cycle return and therefore cannot rotate.
The use of the "Unlimited" or "Limited" traversing ranges for the x axis in the »Cam
editor« is only reasonable for a characteristic.
