Drive Feedback To Network - Danfoss VLT 5000 Instruction Manual

Drive The VLT LonWorks option provides 16 output
variables to the network containing important
Feedback to
drive and motor feedback data. Feedback data
Network
is sent when there is a change in value. The
VLT LonWorks option will only transmit bound
network variables. Since some data changes
continuously, the transmission rate of those
variables is limited. Min send time specifies
the minimum time between transmissions of
variables.
VLT 5000 parameters are shown in parenthesis, where applicable.

The Drive Outputs (1, 2, or 3) will have a
maximum time between transmission set by the
Max send time. This function acts as a transmit
heartbeat and allows a controller node to
determine the health of the controller/VLT
connection. The Max send time function is
disabled when the configuration network
variable nciMaxsendT is not configured or is set
to "0."
