Introduction
The GE FUJI LONWORKS® Interface Card OPC-G11S-LON enables system
integrators to access data on a variable speed drive (VSD) over a LON. It
complements the regular features on the VSD that an operator can access from the
keypad on the drive.
Section 1, Installation, shows how the put the card into the VSD and get it wired to
begin configuration.
Section 2, Configuration, explains how to set up the card to communicate with the
VSD.
Physical Description
The Interface Card is a printed circuit assembly inside a plastic housing that mounts
between the VSD body and keypad. It connects to the drive through a multi-pin
connector and has a removable screw-terminal receptacle that is used to connect to
the LON cable.
Electrical Description
The Interface Card contains its own microprocessor and memory. It communicates
with the VSD through a serial communications channel on the regulator board
connector. Power to the Card is provided by the VSD through the multi-pin
connector and is isolated by a power converter.

Installation
This chapter covers the installation of the LONWORKS Interface Card into the AF300 G11 or P11 variable speed drive (VSD) and the physical connection to the
LON.
The Interface Card is shipped enclosed in a plastic housing that you have to install
into the drive. The assembly is designed to integrate seamlessly within the VSD
under the keypad so that the NEMA rating of the drive is maintained. Figure 1
shows the Card assembly.
Follow the procedure to install the assembly in the VSD.
To remove the keypad:

You can power up the drive and then go to Section 2, Configuration, for information
about configuring the VSD with the software interface.

Configuration
All configuration data is stored in a master file in the VSD. This is so that, whether
you configure the VSD through the keypad or the Interface Card, you will be
looking at the same configuration settings.
Bringing the VSD onto the Network
To add the VSD node to the building network:
‡ 8VLQJ\RXUQHWZRUNWRROIRUH[DPSOH/RQ0DNHU&LUFRQ6\VWHP,QWHJUDWRUHWFDGGWKH96'
WR\RXUQHWZRUN
The first time you try to bring the VSD onto the network an Er4 type error may
occur on the VSD. If this happens, press the Reset button on the VSD keypad; when
the reset is complete the drive will be ready to configure.
Starting the VSD
The network variable nvidrvSpeedSetpt sets the speed of the drive. (See Tables 1-3
for network variable descriptions.)
VSD Network Interface
After the VSD is online you can monitor the it and set the configuration variables
that represent the most common functions used in HVAC applications of VSDs.
To get the current configuration parameters from the VSD to Node Editor you have
to upload them after the VSD is online.
Status LEDs
The LONWORKS interface card has six LEDs that show the communication status of
the VSD. Figure 5 shows the LED functions.

Network Variables
There are four types of network variables that enable the VSD to communicate with
your PC through the Interface Card:

• 2XWSXWYDULDEOHV
• ,QSXWYDULDEOHV
• 6SHFLDOSXUSRVHYDULDEOHV
Configuration Variables
Table 1 shows the configuration network variables that you can set through your
network tool or through the VSD keypad. The function codes shown in the table are
from the VSD and are mapped to the variable in the same row of the table.

Output Variables
Output variables provide operational data about the VSD and the motor it is driving.
Table 2 lists the output variables, corresponding function codes, and descriptions.
The function codes for the output variables are type M (monitoring) codes. All the
output variables associated with type M function codes rely on the nciMinTmOut
and nciSndHrtBt configuration variables to keep output data current.

Special Purpose Variables
Table 5 contains VSD function codes that don’t have their own corresponding
network variables. These codes complement the function codes associated with the
configuration variables in Table 1. For example, the auto-start frequency fall rate
(H14 in Table 5) uses the value in the nciRampDownTm variable (F08 in Table 1) as
a reference.
The Interface Card gives lets you program these function codes with a PC instead of
the VSD keypad by using the following special purpose variables:
• QYL:ULWH3DUDP9DO
• QYL:ULWH3DUDP1XP
• QYL5HDG3DUDP1XP
• QYR5HDG3DUDP9DO
Use the index numbers in Table 5 to represent the VSD function codes.
