Bus length The maximum possible bus length of a CAN network depends on bit rate (transmission rate)
and cable type. The sum of all bus segments must not exceed the maximum bus length
Bit Rate (speed)
1 Mbit/s
800 kbit/s
500 kbit/s
250 kbit/s
125 kbit/s

Types of bus For CANopen, only bus cables with characteristics as recommended in ISO 11898 are to be
cables used. The requirements for the bus cables depend on the length of the bus segment. Regarding
this, the following recommendations are given by ISO 11898:
2022/01/31
5-pin COMBICON
ISO 11898, potential-free
CANopen (CAN), 1 Mbaud max.
10 kbit/s, 20 kbit/s, 50 kbit/s, 100 kbit/s, 125 kbit/s, 250 kbit/s, 500
kbit/s, 800 kbit/s and 1 Mbit/s,

inserted
NOTICE!
Unused connector!
Make sure that the terminal block is always connected to the terminal base or
communication module, even if you do not use the interface.
