Throughout this manual, the following notes are used to alert you to safety
considerations:
ATTENTION: Identifi es informat ion about practices or
circumstances that can lead to personal injury or death, property
damage, or economi c loss.
!
Important: Identifies information th at i s c riti cal for s uc cess ful a ppl ic ati on and
understanding of the product.
ATTENTION: The drive ma y contain hig h voltages t hat can cause
injury or death. Remove all power from the drive, and then verify
power has been removed before installing or removing an RS485
!
DF1 module. Failure to observe these precautions could result in
severe bodily injury or loss of life.
ATTENTION: Only qualified electrical personnel familiar with
drive and power products an d the associated machinery sho ul d
plan or implement the install at ion, start u p, conf i gu ration, and
subsequent mainten ance of the product using an RS 485 DF1
module. Read and und er stand th is manual in its entirety before
proceeding. Failure to observe these precautions could result
bodily injury and/or damage to equipment.
ATTENTION: DPI host prod uct s mus t no t be dir ec t l y con ne ct ed
together via RECBL-xxx cables. Unpredictable behavior due to
timing and other internal procedures can result if two or more
devices are connect ed in this manner. Failure to observe this
precaution could result in bo di ly in jury and/or damage to
equipment.
ATTENTION: If the RS485 DF1 module is transmitting control
I/O to the drive, the drive ma y fa ul t when you reset the module.

Failure to observe this pre caution could result bodily inju ry
and/or damage to equipment.
ATTENTION: Comm Flt Acti on (paramete r 10) lets you de termine
the action of the module and connected drive if communications
are disrupted. By default, this parameter faults the drive. You can
set this p ara meter so that the d rive co ntin ues t o run. Preca ution s
should be taken to ensure that the setting of this parameter does
not create a hazard of injury or equipment damage. When
commissioning the dr ive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or a faulted controller). F ailu re to observe this precaution co ul d
result bodily injury and/o r da m age to equipment.
ATTENTION: When a system is configured for the first time, there
may be unintended or incorrect machine motion. Disconnect the
motor from the machine or process during initial system test i ng.
Failure to observe this precaution could result in bodily injury

RS485 DF1 Communications Module
CHAPTER 1
Introduction
This manual provides information about the RS485 DF1
Communications module (RECOMM-485) and using it with DPI
AC drives, such as SP600 drives. It is intended for qualified
electrical personnel familiar with installing, programming, and
maintaining AC drives and networks.
The RS485 DF1 Communications module allows an RS485 DF1
Master device to access the SP600 drive using:
• Logic Command/Reference (Start, Stop, Reference, etc.)
• Logic Status Feedba ck
• Datalinks A-D
• Explicit Messages
It also allows VS Utilities configuration software (version 1.01 or
higher) to connect to an SP600 drive using a Serial Converter
module (RECOMM-232 ) and co mmun icate with othe r SP600 dri ves
using an RS485 connection.
The module is mounted in the drive an d receive s its required power
from the drive. It can be used with other products that implement
DPI, which is a peripheral communication interface. Refer to the
documentatio n for your prod uct for sp ecific informa tio n about ho w it
works with this module.
1.1 Module Features
The RS485 DF1 Communications module features the following:
• Switches that ena ble y ou to set a no de ad dress and n etwor k dat a
rate before applying power to the drive. Alternatively, you can
disable these switches and use parameters to configure these
features.
• Status indicators that report the status of the drive
communications, module, and network. They are visible both
when the cover is opened and when it is closed.
• I/O, including Logic Command/Reference and up to four pairs of
Datalinks that may be configured for your application using a
parameter.
Introduction

• A number of tools to configure the module and connected drive.
These tools include the LCD OIM and VS Utilities software.
• User-defined fault ac tions that determine how the modu le and the
drive respond to communication disruptions on the network.

1 Review the safety precautions for the
module.
2 Verify that the drive is properly installed.
3 Commission the module.
Set a unique node address and the
appropriate data rate using the switches on
the module. If desired, you can disable the
switches and use parameter settings
instead.
4 Install the module.
Verify that the drive is not powered. Then,
connect the module to the network using an
RS485 cable and to the drive using the
Internal Interface cable. Use the captive
screws to secure and ground the module to
the drive.
5 Apply power to the module.
Apply power to the drive. (The module
receives power from the drive.) The status
indicators should be green. Refer to chapter
6 for more information if there is a problem.
6 Configure the module for your
application.
Set the parameters for the follo wing fe atures
as required by your application:

Chapter 3 provides instructions for installing the module on an
SP600 drive.
3.1 Preparing for an Installation
Before installing the module, verify that you have all required
equipment. Refer to chapter 2, Getting Started, for a list of
equipment.
3.2 Commissioning the Module
To commiss ion th e modu le, yo u must set a un ique no de address o n

Glossary for more information about these error-checking
methods.)
Important: New settings are recognized only when power is
applied to the module or it is reset. If you change a
setting, cycle power or reset the module.
