Baud Rate Setting/Line Length; Setting Node Address - BONFIGLIOLI actice Instruction Manual

4.4
The setting of the baud rate must be identical in all nodes on the system bus. The
maximum possible baud rate is based on the necessary overall line length of the sys-
tem bus. The baud rate is set via the parameter
possible line length.
A baud rate under 50 kBaud, as is 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. If they are made complete use of, a
calculation of the admissible length is to be done on the basis of the line parameters
and the bus driver (PCA82C250T).
4.5
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
Thus, the system bus possesses a maximum number of 63 nodes (Network nodes),
plus one frequency inverter as a master.
