4.8 TopLine C control terminals
Devices of the TopLine C version have identical connections as described under ”HighLine
C control terminals” ( 80). The additional control terminals of the TopLine C version are
described in the following.
4.8.1 Axis bus

Note!
This connection is not supported in versions below 8400 TopLine, SW version
02.00. This connection must not be wired in these lower versions.
The axis bus connection serves to implement two functionalities:
ƒ Synchronisation via state bus
ƒ CAN synchronisation
I/O axis 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 controlled 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 connected 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 connect an external voltage to the state bus, otherwise the function
will be disturbed.
