Assembly / Installation Notes
Wiring diagram for CAN 2 system bus
Cable specification • Use a 4-core twisted and shielded copper cable (data transmission cable with
braided copper shield). Clamping without conductor end sleeves is possible in accor-
dance with IEC 60999. The cable must meet the following specifications:
– Core cross section 0.25 ... 1.0 mm
2
(AWG 23 ... AWG 18)
– Line resistance 120 Ω at 1 MHz
– Capacitance per unit length ≤ 40 pF/m at 1 kHz
Suitable cables include CAN bus or DeviceNet cables.
Cable length • The permitted total cable length depends on the baud rate setting of the system bus:
– 125 kbaud → 320 m
– 250 kbaud → 160 m
– 500 kBaud → 80 m
– 1000 kbaud → 40 m
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). Switch off the terminating resistors on all other units (MOVIDRIVE
®
B, DIP
switch S12 = OFF; MOVITRAC
®
B, DIP switch S1 = OFF). If, for example, the
MOVI-PLC
®
advanced DH.41B control card is at the end of the CAN 2 system bus,
connect a terminating resistor with 120 Ω between pin X32:2 and pin X32:3 (with
CAN 1: terminating resistor between X33:2 and pin X33:3).

• There should not be any potential displacement between the units connected via
the CAN 2 system bus.
• There must not be any potential displacement between the units connected via the
CAN 1 system bus.
• Take suitable measures to avoid potential displacement, such as connecting the unit
ground connectors using a separate cable.
