4.4 Baud rate setting/line length

The setting of the baud rate must be identical in all subscribers on the system bus.

he maximum possible baud rate is based on the necessary overall line len

th of the

system bus. The baud rate is set via the parameter

Baud-Rate 903 and thus defines

the possible line length.

Operation mode Function max. line length

3 - 50 kBaud Transmission rate 50 kBaud 1000 meters

4 - 100 kBaud Transmission rate 100 kBaud 800 meters

5 - 125 kBaud Transmission rate 125 kBaud 500 meters

6 - 250 kBaud Transmission rate 250 kBaud 250 meters

7 - 500 kBaud Transmission rate 500 kBaud 100 meters

8 - 1000 kBaud Transmission rate 1000 kBaud 25 meters

A baud rate under 50 kBaud, as defined accordin

to CANopen, is not sensible for the

system bus as the data throughput is too low.

The maximum line lengths stated are guidelines. If they are made complete use of,

the admissible len

th is to be calculated on the basis of the line parameters and the

bus driver (PCA82C250T)

4.5 Setting node address

A maximum of 63 slaves or frequency inverters with system bus can be operated on

the system bus. Each frequency inverter is

iven a node ID, which may only exist

once in the system, for its unambi

uous identification. The settin

of the system bus

node ID is done via the parameter

Node-ID 900.

Parameter Setting

No. Description Min. Max. Factory setting

900 Node-ID -1 63 -1

hus, the system bus possesses a maximum number of 63 subscribers (Networ

nodes), plus one frequency inverter as a master.

Note:

With the factory setting of parameter

Node-ID 900 = -1, the system bus

is deactivated for this frequency inverter.

If the

Node-ID 900 = 0 is set, the frequency inverter is defined as a mas-

ter. Only one frequency inverter on the system bus may be defined as a

master.
