- the traverse device 16 is driven via a traverse drive 16.1
- the traverse drive 16.1 is likewise controlled via the electronic drive unit 18 of the winder device 3.

- digital signals can be supplied to the pump controller 7.2 in order, for example, to indicate an operating state of one of the spindle drives.
- binary signals of the signal line 26 and control line 25 could be brought about in a simple way by the interlinking of different operating states.
- the pump controller 7.2 has a software module 29 which could stipulate various operating states by programming.
