1 SAFETY INFORMATION
1.1 SAFETY WARNINGS
NOTE!
Only use the CFW500-CRS485-B or
CFW500-CRS485-B-PNP Plug-in
Module in CFW500 WEG inverters.
We recommend reading the CFW500
user’s manual before installing or
operating this accessory.
This guide contains important
information for the correct understanding
and proper operation of this module.
1.2 PRELIMINARY RECOMMENDATIONS
ATTENTION!
Always disconnect the general
power supply before connecting or
disconnecting the accessories of the
frequency inverter CFW500.
Wait for at least 10 minutes to
guarantee complete de-energization
of the inverter.
2 GENERAL INFORMATION
This guide shows how tho install, configure and operate
the CFW500-CRS485-B or CFW500-CRS485-B-PNP
Plug-in Module.
NOTE!
The CFW500-CRS485-B-PNP
accessory must only be used with
the main software version equal to
or above the version V2.06 for the
CFW500, 1.85 for the CFW501 or
version V2.00 for the MW500.

3 CONTENTS OF THE PACKAGE
When receiving the product, check if this package
contains:
Accessory in anti-static packaging.
Installation, configuration and operation guide.
4 ACCESSORY INSTALLATION
The accessory is easily installed or replaced. For correct
installation of the accessory execute the following steps:
Step 1: With the inverter power supply off, remove the
front cover of the Inverter (figure A.1 (a)).
Step 2: Remove the accessory (connected plug-in
module) if any, as in figure A.1 (a).
Step 3: Fit and press the accessory to be installed as
indicated in figure A.1 (b) and then assemble the front
cover of the inverter.
Step 4: Power up the inverter and check if parameter
P0027 shows value 9 (P0027 = 9, for CFW500-CRS485-B)
or the value 15 (P0027 = 15, for CFW500-CRS485-B-PNP).
If this information is not true, check if the module used is
actually the CFW500-CRS485-B or CFW500-CRS485-B-
PNP and repeat steps 1-4.

NOTE!
For the CFW500-CRS485-B-PNP module,
the digital inputs are fixed at active high
(P0271 = 8). It is not possible to set P0271
different from 8.
The location of the DIP-switches for selecting the type
of analog input and output signal and termination of
the RS485 line can be better visualized in figure A.2.
To use the analog inputs and/ or outputs with signal in
current, switch S1 and related parameters must be set as
indicated in table 2 . For further details about the control
connections see chapter 3 - Installation and Connection
of the CFW500 user's manual.
