8.13.1 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 values are not assured limits:
l
Characteristic impedance: 100–120 Ω
l
Cable capacitance max.: 60 nF / 1000 m
l
Lead loop resistance: 159.8 Ω / 1000 m
Transmission Rate (kBaud) 1000 500 250 125
Maximum Cable Length (m) 25 100 250 500
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 terminating resistor 150 ± 5
Ω.
Communication profile
For CANopen communication profile description refer to the manual "AKD2G CAN-Bus Communication".
