Baud rate setting/line lengths

The Baud rate settings must be the same in all subscribers. The maximum Baud rate
depends on the necessary total cable length of the system bus. The Baud rate is set
up via parameter
Operation mode
3 - 50 kBaud
4 - 100 kBaud
5 - 125 kBaud
6 - 250 kBaud
7 - 500 kBaud
8 - 1000 kBaud
A baud rate under 50 kBaud, as defined according to CANopen, is not sensible for the
system bus as the data throughput is too low.
The maximum line lengths stated are guidelines.
Depending on the number of subscribers, the baud rate is limited. There are the fol-
lowing restrictions:
Up to and includ-
ing
The bus load must be considered in the projecting phase.

Setting the node address

A maximum of 63 slaves or frequency inverters with system bus can be operated on
the system bus. Each frequency inverter is given a node ID, which may only exist
once in the system, for its unambiguous identification. The setting of the system bus
node ID is done via the parameter
No.
900 Node-ID
Thus, the system bus possesses a maximum number of 63 subscribers (Network
nodes), plus one frequency inverter as a master.
