8.12.1 CAN-Bus Topology
We recommend the use of Kollmorgen CBP000 cables.
Cable requirements
To meet ISO 11898, a bus cable with a characteristic impedance of 120 Ω should be used.
The maximum usable cable length for reliable communication decreases with increasing
transmission speed.
As a guide, you can use the following values measured by Kollmorgen; however, these val-
ues are not assured limits:
Characteristic impedance: 100–120 Ω
Cable capacitance max.: 60 nF / 1000 m
Lead loop resistance: 159.8 Ω / 1000 m

Lower cable capacitance (max. 30 nF / 1000 m) and lower lead resistance (loop resistance,
115 Ω / 1000 m) allow larger distances. The characteristic impedance 150 ± 5 Ω requires ter-
minating resistor 150 ± 5 Ω.
