Drive

Feedback to

Network

The VLT LonWorks option provides 22 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 Output 1 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.”
