TR1 Series VFD Installation And Operation Manual

TR1 Series
Common applications for the Trane TR1 Series
VFD VFD include the following.
Applications
• The TR1 is factory mounted or field
• The TR1 is field applied using closed loop

drive, the unit enables the drive to
communicate with other devices on the LON.
The TR1 Series drive is designed to provide
precision control of standard induction electrical
motors for HVAC applications. The drive
receives three reference signals along with
start/stop and reset commands from the
network. The drive also receives a 16-bit control
word that provides full operational control of
the drive. (See Network Drive Control Input for
additional details.)

a LonWorks network may or may not require
the use of a network management node. A
network management node performs
management functions, such as:
• Find unconfigured nodes and download
• Stop, start, and reset node applications.
• Access node communication statistics.
• Configure routers and bridges.
• Download new applications programs.
• Extract the topology of a running

network.
• The TR1 can be controlled digitally when
used in conjunction with Trane's AH540
and MP580 Comm 5 (LON) controllers.
• The TR1 could be operated in an open
loop control method and, under certain
circumstances, an override or contact
closure can send the drive to a preset
value.
In response, the drive provides 16 output
network variables containing important drive
and motor data. (See Drive Feedback to
Network.) Output to the network includes drive
status, current, voltage, motor and inverter
thermal status, and alarms and warnings.
The TR1 Series VFD LonWorks free topology
option card, 176F1515, supports four
transmission media, which also operates on a
link power network (used for Comm 5). A router
is required to interface to a LonWorks network
when not supported by the option card.
Within a Trane BAS system, the Tracer Summit
building controller unit (BCU) and/or Rover
Service tool act as the network managers.
