INFORMATION
When cabling the servo drives via the CAN bus, comply with the following information
and notes in order to ensure a stable and interference-free system. Improper cabling
may cause the CAN bus to malfunction which, in turn, will cause the controller to shut
down with an error for safety reasons.
The CAN bus provides an easy and fail-safe way of connecting all of the components of a system.
However, this requires compliance with the following cabling instructions.
Figure 30: CAN bus cabling example
 The individual nodes of the network are always connected in line so that the CAN cable is looped
through from controller to controller.
 A terminating resistor of 120  must be present on both ends of the CAN bus cable. The
ARS 2300 FS servo drive is equipped with an integrated terminating resistor that can be
activated/deactivated via the DIP switch "CAN TERM" on the front panel.
 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 connected to the CAN shield connectors 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 Metronix specification
 the motor cables are properly shielded and earthed (grounded)
