The traversing speed results from the precontrol signal proportional to the winding speed and the
evaluation setting (traversing step). Limit switches detect the position of the traversing traversing unit
at the reel ends. The traversing drive is decelerated and accelerated with a constant path and
independently of the winding speed.

At the turning points, the traversing drive remains at standstill until the winding drive has traversed
a specified angle of rotation.
Traversing step
For the traversing speed and the traversing step, the reference setpoint (winding speed via X6/1,2)
is multiplied by C0472/1.
With a reference setpoint of 10 V and an evaluation of C0472/1 = 100 %, the traversing drive reaches
the speed selected under C0011 (n
max
).
Additional setpoint
Via X5/E3 you can activate an internal additional setpoint (C0471) which is added to the reference
setpoint via the FB ADD1. The additional setpoint can, for instance, be used to adjust the traversing
drive while the winding drive is at standstill.
