Mounting/Installation Instructions
4.3.3 Connecting system bus CAN 2 (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 ... 63.
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 2x2-core twisted and shielded copper cable (data transmission cable with
braided copper shield). IEC 60999 does allow clamping without conductor end
sleeves. The cable must meet the following specifications:
– Core cross section 0.2 ... 1.0 mm
2
(AWG 24 ... 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.
NOTES
• 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 out-
puts via I/O modules to the MOVI-PLC
®
basic DHP11B.. controller.
• No CAN system bus connection is necessary for communication between MOVID-
RIVE
®
MDX61B and its installed controller MOVI-PLC
®
advanced if you use the
'DPRAM' channel (→ "MOVI-PLC
®
Programming in the PLC Editor" system manu-
al). A CAN system bus connection is, however, necessary if modules from the
MPLCMotion_MDX and MPLCprocessdata libraries are employed.
