8.6 "State bus" monitoring function

The state bus is a bus system that is solely designed for Lenze controllers, via which up to 20

controllers can be connected to each other, and by means of which the function of a "release cord"

can be simulated:

[8-1] Schematic diagram: Networking via state bus

• The state bus only knows the states "OK" and "Error".

• The state bus is a bus with multi-master capability, i.e. each node connected to the state bus can

set the state bus to the "Error" state by setting it to LOW level.

• In the "Error" status, all nodes start their adjustable response, e.g. synchronised braking of the

drive system.

• The "Error" state is also set if a node connected to the state bus is not supplied with voltage.

 Note!

Exception handling:

• In the case of a critical exception within the application (e. g. reset), the "release cord"

is not triggered, the state bus remains in the "OK" status.
