8.1 System bus
With NORDAC inverter technology, units or modules communicate via a dedicated system bus. With the
launch of the SK 200E frequency inverter series and the associated components SK CU4-... and SK TU4-...
functions and interfaces were implemented in this system bus, which enable the user to make appropriate
adaptations.
A decisive advantage is provided by the fact that the system bus is no longer restricted to a single inverter
and a directly connected module, but rather that up to 4 frequency inverters can jointly use a BUS interface
(e.g.: DeviceNet). This increases the number of possible subscribers on a field bus system (by a factor of 4)
with comparatively lower investment costs.
The system bus address of the bus modules (SK CU4-
… and SK TU4-…) is set to "30". The system bus
address of the up to 4 frequency inverters which can be connected are set by means of DIP switches (see
manual BU0200) on the relevant frequency inverter, optionally between 32 / 34 / 36 and 38, whereby no
address may be doubly assigned within a system bus system.
