Network Configuration Properties (Nci); Network Drive Control Input - Trane LonWorks



TR1 Series VFD Installation And Operation Manual

Network
The TR1 Series VFD LonWorks option card
Configuration supports LonMark network design to improve
interoperability.
Properties
(Nci)
The configuration parameters are network
variable inputs to the drive. Configuration of
parameters needs setting only one time, usually
at installation. See the table below for
definitions.

Network
The most common functions for controlling the
Drive TR1 Series Variable Frequency Drive from the
LonWorks network are made readily available.
Control
Those functions and their descriptions are
Input
presented in the table below. The control word
function accesses additional drive capabilities
for network control. The installer must verify
that parameter 500, Protocol, is set for FC
protocol.

Part of the LonMark Functional Profile for Variable Speed Drive 6010 starting with version 1.1
Network variable nviDrvSpeedStpt is comprised of a stop/start command (state) and a separate speed command
(value). 0 is a stop command and 1 is a run command. Drive speed is a function of the reference signal between 0
and 100%.

The choice of open loop or closed loop operation
of the drive is selected in parameter 100,
Configuration.
For open loop control, it is recommended to
set the following parameters:
201 = 0 Hz
202 = 60 Hz
203 = LINKED TO HAND/AUTO
204 = 0.0
205 = 60.0
