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 i n 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 i s controlled via the system module SFBDigitalOutput.

ƒ The state bus knows the states ”OK” and ”fault”.

ƒ The s tate bus i s multi-master-compliant, i.e. each node connected to the state bus

can set the state bus t o ”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.
