Continuous motor cable shield or enclosure for equipment on the motor cable
To minimize the emission level when safety switches, contactors, connection boxes or similar equipment are
installed on the motor cable between the drive and the motor:
– European Union: Install the equipment in a metal enclosure with 360 degree grounding for the shields of
both the incoming and outgoing cable, or connect the shields of the cables otherwise together.
– US: Install the equipment in a metal enclosure in a way that the conduit or motor cable shielding runs
consistently without breaks from the drive to the motor.
DCSLink wiring
The DCSLink is a 500 kBaud serial communication between drives and drives to field exciters.
It is based on CAN hardware and using twisted cables.
The topology is a bus system.
Switched OFF nodes can remain in the bus and do not disturb the serial communication.
The function of the interface is predefined:
1. Communication to field exciter types DCF803, DCF804 and large field exciters using standard
DCS880 modules.
2. Communication for 12-pulse operation, DCS880 to DCS880.
Cabling
Every bus device requires its own individual node number.
Only two physical ends are allowed for the bus system.
The termination resistance of 120 Ohm is selected for typical twisted pair cables. The cables must be
terminated at both ends. This is done using jumpers or switches inside the drives or field exciter.
Maximum total cable length is 100 m.
Preferred cable type: DEVICENET
