5.1.6 Traversing range
The selection of the traversing range ("Unlimited", "Limited", or "Modulo") in the Traversing range
list field ( C02528 ) serves to define the machine measuring system.
"Unlimited" traversing range
The drive can rotate continuously in one direction.
• By referencing and activating the software limit positions the traversing range can be limited.
• For positioning with absolute travel command the home position must be known.
[5-5] Unlimited traversing range, taking the "feed control tape" as an example
"Limited" traversing range
The travel range is limited by positive and negative position limits (mechanical limits/travel range
limit switches/software limit positions).  Limiter ( 536)
• After a defined distance the drive must travel in the opposite direction again.
• For positioning in the limited traversing range the home position must be known.
• The software limit positions are basically monitored with regard to the maximum value range
that can be represented internally (±2 31 increments), even if monitoring has been deactivated
via C02700 .
• An overflow of the value range results in a loss of the reference information.
[5-6] Example: Limited traversing range - "spindle drive" (linear axis)

Note!
A change-over of the traversing range results in a loss of the reference information!
