VLT is a registered Danfoss trademark
Ethernet network connection
The Ethernet network connects directly to the BACLink Ethernet
portal (refer back to Figure 1). The connection is a 10baseT port.
Both Ethernet and Ethernet IP (BACnet IP) connect through this
connector.
To establish Ethernet communication with the BACLink portal and
VLT drives, the following must be completed:
1.Wiring
2.Setting IP address of portal
3.For port 2 connection, setting port 2 configuration jumpers
Procedure
1. Wiring
Wire Connections
. Each BACLink portal can support up to 10
drives (see Figure 7). Any mix of VLT 2800 or VLT 6000 drives is
supported.
The preferred portal-to-drive wiring is EIA-485 from port 2.
Connect portal Net+ to drive terminal 68 (+) and Net- to 69 (-).
Additional drives are connected pos-to-pos and neg-to-neg in
daisy chain fashion.
If required, port 1 can be factory-configured to connect the drives
through EIA-485.
