SED2 VFD LON Interface Option Operating Instructions
LON Interface Option Overview
General Description
The L
ONMark® certified SED2 VFD LON
Interface Option provides direct digital control
of SED2 Variable Frequency Drives (VFDs).
The SED2 VFD can reside on a LONWorks®
network, enabling information sharing with all
other L
ONMark products from multiple vendors.
The SED2 VFD L
ON Interface Option is
LONMark-compliant with Variable Speed Motor
Drive Functional Profile Number 6010. The
SED2 VFD LON Interface Option uses standard
network variable types for communication,
allowing a SED2 VFD to be configured,
controlled, and monitored via the LONTalk®
network. A network management tool installs
the SED2 VFD on the network and binds the
network variables to other devices on the
network for seamless integration.
The L
ON Interface Option’s modular snap-on
design facilitates simple installation and
enables easy control system integration via any
existing or new SED2 VFD. The SED2 VFD
L
ON Interface Option offers a cost-effective
solution by reducing system installation and by
allowing direct integration to control systems.

For example, an air handling unit controller sends messages to control the start/stop and speed
reference of the SED2. The VFD outputs messages such as the actual drive speed and the
output current to the controller, operating interfaces, and energy management systems.
