Feedback to
Network The VLT LonWorks option provides 16 output
variables to the network containing important
drive and motor feedback data. Feedback data
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.
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.”
