State bus
The state bus is a bus system exclusively designed for Lenze controllers via which up to 20
controllers can be connected and which serves to simulate a ”release cord” function. The
state is c ontrolled via the system module SFBDigitalOutput.
ƒ The state bus knows the states ”OK” and ”fault”.
ƒ The state bus is multi-master-compliant, i.e. each node c onnected to the state bus
can set the state bus to ”fault” by changing to LOW level.
ƒ In the ”fault” status, all nodes activate their programmed response, e.g.
synchronised braking of the drive system.
 Stop!
Do not c onnect an external voltage to the state bus, otherwise the function
will be disturbed.
