Figure 31: CAN bus cabling example
▪ Ideally, the individual nodes of the networks are always connected in a linear manner so that the CAN cable is looped
through from servo drive to servo drive.
▪ A terminating resistor of 120 Ω, 5%, must be present on both ends of the CAN bus cable.
▪ Shielded cables with exactly two twisted pairs must be used for cabling.
▪ Use one twisted pair to connect CAN-H and CAN-L.
▪ The cores of the other pair are used jointly for CAN-GND.
▪ The shield of the cable is led to the CAN shield connections for all nodes.
▪ We advise against the use of plug adaptors for cabling the CAN bus. However, if this is necessary, use metal connector
housings for connecting the cable shield.
In order to keep interferences as low as possible ensure that
▪ the motor cables are not installed parallel to signal lines
▪ the motor cables comply with the Item specification
▪ the motor cables are properly shielded and earthed (grounded)
