8.10.4 Cable type and design [X4]
The mentioned cable denominations refer to cables by Lapp. They have proven effective and are
successfully used in many applications. However, similar cables from other manufacturers, for
example Lütze or Helukabel, may also be used.

8.10.5 Connection notes [X4]
Caution!
When cabling the servo drives via the CAN bus, make sure to observe the following
information and notes, to ensure a stable and interference-free system. Improper
cabling may cause the CAN bus to malfunction which in turn can cause the servo drive
to shut down with an error for safety reasons.
The CAN bus provides a simple and fail-safe way of connecting all components of a system,
assuming, however, compliance with the following notes on cabling.
Figure 25:
Cabling example for CAN-Bus
The individual nodes of a network are always connected in line, so that the CAN cable is looped
through from servo drive to servo drive (see
On both ends of the CAN bus cable must be exactly one terminating resistor of 120
+/- 5 %. All
ARS 2100 SEseries servo drives are equipped with an integrated terminating resistor that can be
activated/deactivated with the aid of the DIP switch “CAN TERM” that is located on the front panel

cables with exactly two
twisted
pairs must be used for cabling
