1. INTRODUCTION
GENERAL
The purpose of this manual is to provide general information, installation, and
operation procedures for the FR-A5ND DeviceNet option, used with the
FR-A500(L) Variable Frequency Drive, herein after referred to as the VFD.
Read this manual completely before installing, operating or servicing the
option unit.
This manual is intended for use by qualified personnel. Installation should
only be performed by qualified personnel. You must be able to operate and
program serial devices to use the equipment.
This option allows the VFD to be connected to a network adhering to the
DeviceNet communications protocol.
Illustrations provided in this manual may have covers or safety guards re-
moved to provide a clear view. Before starting operation of the product be sure
to install covers and guards into the original position.
The following is a list of important features for the option unit
 Data Rates of 125K baud, 250K baud, and 500K baud.
 Up to 64 stations supported on a single network
 Ability to add or remove stations without disrupting network operation.
 Network access to all VFD parameters, Start/Stop commands, and moni-
tor data.
 Passed ODVA Conformance Test in January, 1998
 Designed and assembled in the U.S.A..
DESCRIPTION
The FR-A5ND option unit consists of two circuit boards as shown in Figure
1-1. The option unit is mounted in option port #3 on the VFD unit. Two station
switches, mounted on the top printed circuit board, allow the assigning of
station numbers from 0 to 63. An LED status light mounted next to the
DeviceNet connector provides status information on the communication link.

2. INSTALLATION
Installation requires the removal of the VFD cover. The VFD top cover must
be removed to install the option unit. After installation, the top cover is rein-
stalled and connection to the DeviceNet bus is completed through a connec-
tor accessible through the top cover.
WARNING: Cover removal can expose charged components. Be sure the
proper procedures are followed when removing cover.
Remove cover following the procedure in the VFD manual.

2.2. Installation Procedure
Mounting Option Unit In VFD Option Port #3.
1. Verify that power has been turned off and that the VFD top cover has
been removed.
NOTE: The FR-A5ND option unit must be installed in Option Port #3 only.
An attempt to install in any other port may cause the VFD or the
option unit to be damaged.
2. Using the two mounting holes for alignment reference, carefully insert
the option unit connector into the VFD connector as shown in Figure 2-
1 and firmly press the unit into place.
NOTE: If screw holes in option unit do not line up with the VFD mounting
holes, check that connector has been correctly fitted.
3. Secure the option unit to the VFD with the two mounting screws.
4. Option unit is now mechanically installed as shown in Figure 2-2.
