Assembly / Installation Notes

3.3.3 Connecting system bus CAN 2 (terminal X32) / CAN 1 (terminal 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 on

the system bus. This manual can be ordered from SEW-EURODRIVE.

• The CAN 2 system bus is electrically isolated. Therefore, interface CAN 2 (X32) is

preferred for connecting field devices (e. g. CANopen inputs and outputs).

• The CAN 1 system bus is not electrically isolated. Therefore, use the CAN 1 (X33)

interface to connect the inverter via the system bus in the control cabinet.

• SEW-EURODRIVE connecting a maximum of 64 inputs and 64 outputs to the

MOVI-PLC

basic DHP11B.. control card via I/O modules.

• If you use the "DPRAM" channel (→ "MOVI-PLC

Programming in the PLC-Editor"

system manual), you do not need a CAN system bus connection for communication

between MOVIDRIVE

MDX61B and the installed MOVI-PLC

advanced control

card. However, a CAN system bus connection is required if modules from the

MPLCMotion_MDX libraries and MPLCProcessdata are used.
