Aux Chain - Danfoss VACON 3000 Application Manual

VACON® 3000
Application Guide
When switch on failing mode is selected, the primary fieldbus connection begins to fail sending messages to the drive. Then the
switchover command is given to change to the secondary fieldbus connection. When switch on faulted mode is selected, and the
primary fieldbus connection gets a timeout, the switchover command is given to change to the secondary fieldbus connection.
The switchback functionality forces a change back to the primary fieldbus connection when it is in operational state and when the
given time delay has elapsed. If the switchback functionality is deactivated, the switchover between the fieldbus connections is only
performed when the currently controlling fieldbus begins to fail or becomes faulted.
The currently controlling fieldbus protocol can be checked from the monitoring value V5.13.2 Controlling Fieldbus (ID 2610).

The contents of the menu depend on the units connected to the aux chain. The number of units is configured with parameter AUX
Chain Unit Count (ID 6001). The parameters in
unit has a similar menu and set of parameters (Aux 15, Aux 16, Aux 17).
