4.2.1.6 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.
r By referencing and activating the software limit positions the traversing range can be
limited.
r For positioning with absolute travel command the home position must be known.
[4-4] Example: Unlimited traversing range - "feed control tape"
"Limited" traversing range"
The travel range is limited by positive and negative position limits (mechanical limits/
travel range limit switches/software limit positions). Limiter
(C 200)
r After a defined distance the drive must travel in the opposite direction.
r For positioning with absolute travel command the home position must be known.
r Basically the software limit positions are monitored with regard to the internally
maximally value range to be displayed (±2
31
increments) even if the monitoring mode
has been deactivated via C02700 .
r An overflow of the value range results in a loss of the reference information.
[4-5] Example: Limited traversing range - "spindle drive" (linear axis)
Note!
A change-over of the traversing range results in a loss of the reference
information!
