Function description
To move the carriers, the primary sections are fed with current from various Motor Modules.
Multiple carriers can be traversed open- or closed-loop controlled on the transport path
comprising many primary sections. Each carrier is is individually moved and can be freely
positioned, accelerated, decelerated and synchronized to individual process steps of the
application by the associated closed-loop control.
Depending on the distribution of the primary sections, the carriers can also be moved and
positioned relative to each other.
Note
Carriers can only be traversed independently of one another when they are located on different
motor segments.
The RAILCTRL Technology Extension controls the motion of a carrier beyond segment limits
by coupling the segments and copying the controlled variables from the master to the slave.
