Limited traversing range
• The traversing range is limited by positive and negative position limits (mechanical limits/travel
range limit switches/software limit positions).
• After a defined distance, traversing must take place in the opposite direction again (example:
spindle drive/linear axis).
[8-18] Examples of a limited traversing range
• Typical curves for the limited traversing range:
[8-19] Example 1: Closed curve trace (forward-back profile)
[8-20] Example 2: Closed curve trace (forward-back profile) as a sequence by means of two machine cycles ("weaving loom"
principle)
