1 SAFETY INFORMATION

1.1 SAFETY WARNINGS

NOTE!

 This guide contains important information

for the correct understanding and
proper operation of this CFW500-RS232
Communication Plug-in Module.

 Only use the CFW500-RS232

Communication Plug-in Module
(CFW500-CRS232) in CFW500 WEG
inverters.

 We recommend reading the CFW500

user’s manual before installing or operating
this accessory.

1.2 PRELIMINARY RECOMMENDATIONS

ATTENTION!

 Always disconnect the general power

supply before connecting or disconnecting
the accessories to the frequency inverter
CFW500.

 Wait at least 10 minutes to guarantee

complete de-energization of the inverter.

2 GENERAL INFORMATION

This guide shows how to install, configure and
operate the CFW500-RS232 Communication Plug-in
Module. This plug-in is used in to CFW500 Universal
Asynchronous Receiver Transmitter (UART) interface
in RS232 physical layer. The CFW500-CRS232 allows
the PC serial communications for inverter commands,
reference and variables monitoring, as well as SoftPLC
debugging and programming. For further information
about this refer to the CFW500 "Modbus RTU user's
manual" and "SoftPLC manual " in the CD-ROM.

3 PACKAGE CONTENT

When receiving the product, check if this package
contains:

 Accessory in antistatic package.
 Installation, configuration and operation guide.

NOTE!

Serial cable not included.

4 INSTALLATION OF THE ACCESSORY

The accessory is easily installed or replaced. For the
proper installation of the accessory, follow the steps
below:

Step 1: With the inverter deenergized, remove its front
cover as shown in figure A.1 (a).

Step 2: Remove the accessory (plug-in module
connected), if present, as shown in figure A.1 (a).

Step 3: Position and press the accessory to be installed
as shown in figure A.1 (b) and then connect the front
cover of the inverter.

Step 4: Energize the inverter and check if parameter
P0027 shows the value 7 (P0027 = 7). In case this
information is not true, check if conected module the
CFW500-CRS232 and repeat steps 1-4.

The location of the DIP-switches used to select the
type of analog input and output signal and termination
of RS485 network can be better viewed in figure A.2. In
order to use the analog input and/or output with signal
in current, the switch S1 and related parameters must be
adjusted according to table 1. For further details on the
control connections refer to chapter 3 - Installation and
Connection of the CFW500 user’s manual.

RS232 Communication Plug-in Module

English

CFW500 | 9

The RS232 plug-in module presents the following
features:

 Parameterization, command and monitoring of

the inverter by SuperDrive G2 e WLP application
software (available in CFW500 CD-ROM).

 CFW500 firmware programming/atualization by FDT

application software (available in CFW500 CD-ROM).

ATTENTION!

With switches S2.1=ON and S2.2=ON the
inverter stays in the firmware programing
state. This operation must only be executed
under WEG’s orientation. Improper use of
this application may damage the equipment.

This module has a connector (figure A.2) to enable the
use of the CFW500-MMF Flash Memory Module , which
allows data transfer between inverters. For further details
on this accessory, refer to the installation and operation
guide of the CFW500-MMF.

NOTE!

 When connecting to the PC, the associated

serial port is automatically determined by
the operating system some seconds after
the connection. The user can easily identify
or change the associated COM port in:
Control Panel → System → Hardware →
Device Manager → COM & LPT Ports.

 For further details, refer to the installation

manual available in the CD-ROM.
