1. INTRODUCTION
GENERAL
The purpose of this manual is to provide general information, installation,
and operation procedures for the FR-A5NP Profibus DP 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 unit lets you connect an FR-A500(L) series VFD to a network
adhering to the Profibus DP communications protocol. Profibus DP is the
performance-optimized version of Profibus for time-critical operations.
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 to 12,000,000 bps.
 Up to 126 stations supported on a single network
 Network access to all VFD parameters.
 Certified by Profibus Nutzer Organization in July 1998
 Designed and assembled in the U.S.A..
DESCRIPTION
The FR-A5NP 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. The VFD
top cover must be removed to install the option unit. After installation, the top
cover is reinstalled and connection to the Profibus DP bus is completed
through a connector accessible through the top cover. Two station switches,
mounted on the top printed circuit board, allow the assigning of station num-
bers from 0 to 126. A LED status light mounted next to the connector pro-
vides status information on the communication link.

2.0 INSTALLATION
Remove the drive cover following the VFD instruction manual and install the
option unit using the following procedure:
2.1. Pre-installation Checks
(1) Check the VFD type.
Use the option unit only with an FR-A500(L) series VFD. Do not use it
with any other series (e.g. A200E, A200, A100, Z and F series). These
other series VFDs have a different option connector to prevent installa-
tion. If you force the connector, you may damage the VFD as well as the
option unit.
(2) Make sure the VFD input power is off. The option unit can be damaged if
installed with the input power on.
(3) Make sure the PLC master (or Profibus DP master) is properly grounded
before continuing.
2.2. Mounting Procedure
WARNING: Hazardous voltage present.
Always isolate power from the VFD and wait 10 minutes until
the bus charge light is off to ensure the charge lamp has gone
out before inserting or removing this option unit or touching the
terminals.
(1) Insert this option unit only into the OPTION PORT# 3 of the VFD.
(2) Carefully insert the connector of the option unit into the connector of the
VFD as shown in Figure 2-1. Use the two mounting holes and the guide
hole to align the bottom board with the matching machine screw inserts
and the plastic guide pin on the VFD. Make sure that the VFD option is
firmly seated in the VFD and the connector is fully plugged in.
(3) Secure the option unit to the VFD with two mounting screws. If the screw
holes in the option unit do not line up with the VFD mounting holes,
check that the connectors have been fitted correctly.
