)
Note!
ƒ
Separate control cables/data lines from motor cables.
ƒ
Connect the shields of control cables/data lines at both ends in the case of
digital signals.
ƒ
Use an equalizing conductor with a cross−section of at least 16 mm
2
(reference: PE) to avoid potential differences between the bus nodes.
ƒ
Observe the other notes concerning EMC−compliant wiring given in the
documentation for the standard device.
Procedure for wiring
1. Observe the bus topology, i.e. do not use stubs.
2. Observe notes and wiring instructions in the documents for the control system.
3. Only use cables complying to the specifications listed (
^ 58).
4. Observe the permissible bus cable length (
^ 62)
.
5. Connect bus terminating resistors of 120
W each (scope of supply):
– only to the physically first and last node
– between the terminals CAN_L and CAN_H
