Connecting and installing CAN
CAN Interfaces of MOVIDRIVE® B
Wiring diagram
An 120 ohm terminating resistor can be connected for both CAN interfaces via DIP
switch.
• CAN 1: DIP switch S12 on the MOVIDRIVE
®
B basic unit
• CAN 2: DIP switch "R" on the DFC11B option
CAN network
The CAN network (see figure below) should always have a linear bus structure without
[1] (or only with very short) stub lines [2]. The network must have exactly one terminating
resistor R
T
= 120 ohm installed on both ends of the bus.
MOVIDRIVE
®
B units come equipped with CAN transceivers with a fan-out of more than
100:1. This means you can connect 100 units via CAN network without having to take
special measures.
Cable length
The permitted total cable length depends on the baud rate setting (P884/P894):

→
250 m (820 ft)
• 500 kBaud
→
100 m (328 ft)
