3.4.3 Connection CAN 2 system bus (connector X32) / CAN 1 (connector X33)
Do not connect more than 64 units to the CAN 2 or CAN 1 system bus. The system bus
supports the address range 0 ... 127.
Use a repeater after 20 or 30 CAN bus stations, depending on the length of the cables
and the cable capacity. The CAN system bus supports transmission systems compliant
with ISO 11898. The "Serial Communication" manual contains detailed information
about the CAN system bus. This manual can be ordered from SEW-EURODRIVE.
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). IEC 60999 does allow clamping without conductor ender
sleeves. The cable must meet the following specifications:
– Core cross section 0.25 ... 1.0 mm
2
(AWG 23 ... AWG 18)
– Line resistance 120
Ê
at 1 MHz
– Capacitance per unit length
Â
40 pF/m at 1 kHz
Suitable cables include CAN bus or DeviceNet cables.
• The CAN 2 system bus is electrically isolated. Therefore, it is recommended to use
the CAN 2 (X32) interface for connecting field devices (e.g. CANopen inputs and
outputs).
• The CAN 1 system bus is not electrically isolated. Therefore, it is recommended to
use the CAN 1 (X33) interface to connect inverters via the system bus in the control
cabinet.
• SEW-EURODRIVE recommends connecting a maximum of 64 inputs and 64 outputs
via I/O modules to the MOVI-PLC
®
basic DHP11B.. .
• No CAN system bus connection is necessary for communication between MOVI-
DRIVE
®
MDX61B and its installed controller MOVI-PLC
®
basic DHP11B.. if you use
the "DPRAM" channel (

System manual "MOVI-PLC

programming in PLC Editor).
A CAN system bus connection is, however, necessary if POUs from the
MPLCMOTION_MDX and MPLCprocessdata libraries are employed.
