Assembly and Installation Notes
Cable length
•
The permitted total cable length depends on the baud rate setting of the system bus:
– 125 kBaud
→
500 m
– 250 kBaud

Terminating
resistor
•
Switch-on the system bus terminating resistor at the start and end of the CAN system
bus connection (MOVIDRIVE
®
B, DIP switch S12 = ON; MOVITRAC
®
B, DIP switch
S1 = ON). For all other devices, switch off the terminating resistor (MOVIDRIVE
®
B,
DIP switch S12 = OFF; MOVITRAC
®
B, DIP switch S1 = OFF). For example, if the
DH.21B/DH.41B option is located at the end of the CAN 2 system bus, you have to
connect a terminating resistor of 120
Ω
between pins X32:2 and X32:3 (for CAN 1:
terminating resistor between pins X33:2 and X33:3).

RS485 interface connection (X34)
You can connect one of the following units to each of the RS485 interfaces COM1/2
(terminal X34).

NOTICE
•
There
must not
be any potential displacement between the units connected via
CAN 2 system bus.
•
There
must not
be any potential displacement between the units connected via
CAN 1 system bus.
•
Take suitable measures to avoid potential displacement, such as connecting the
unit ground connectors using a separate cable.
NOTICE
•
There must not be any potential displacement between the units connected via
RS485. Take suitable measures to avoid potential displacement, such as
connecting the unit ground connectors using a separate cable.
•
Dynamic terminating resistors are installed.
Do not connect any external
terminating resistors.
