Modulo traversing range
The drive can rotate continuously in one direction.
If the set cycle is exceeded, a defined overshoot takes place, i.e. the value range repeats itself
periodically (example: rotary table).
In a rotating system, the cycle corresponds to a typical rotation (360°) or a distance between
tools.
Depending on the branch of industry, the cycle is also called "register", "register length", "arc
length", "arc size", "format cut length", etc.
Absolute targets can be approached by exceeding the measuring system limit, e. g. from 10° to
350°.

Note!
In the modulo traversing range the feed (lift) defined by the motion profile has to
correspond to the cycle, i. e. the curve has to be completed with the cycle end!
