Configuration Of The Module - WEG CFW-11 User Manual

The Profibus DP network cables must be laid separately (and far away if possible) from the power cables. All the
drives must be properly grounded, preferably at the same ground point. The Profibus cable shield must also be
grounded. The DB9 connector itself already has a connection with the protective ground and, therefore, makes
the connection of the shield to the ground when the Profibus cable is connected to the drive. However a better
connection, implemented by clamps that connect the shield to a ground point, is also recommended.

Configuration of the Module

In order to configure and use the Profibus DP-V1 module, follow the steps below:
With the module installed, during the acknowledgement stage, a warning message will be displayed on the

product HMI, and the ST and OP LEDs test routine performed. Then the ST LED of the module must turn
on in green.
Observe the content of parameter P0723. Check if the module was recognized. The detection is done

automatically and does not require the user's intervention.
Set the parameters as desired for the application:

Address: the address of the equipment is set in parameter P0725.

I/O configuration: Program in P0727 the number of words to be exchanged with the network master.

This same value must be set in the Profibus master. For this adjustment being complete, it is necessary
to program a value different from 0 (zero) in parameters P0728 to P0739 (see item 3).
Once the parameters are set, if any of the parameters described in the previous item are changed, it is

necessary to restart the equipment.
Once the equipment is set, it is necessary to configure the communication in the master of the network:
GSD file: every element of the Profibus DP network has an associated configuration file with extension GSD.

This file describes the features of each device and it is used by the configuration tool of the master of the
Profibus DP network. During the configuration of the master, the GSD configuration file, supplied with the
equipment, must be used. This file must be registered in the master of the Profibus DP network. The
module will be recognized as "
I/O data setting: add the CFW-11 to the device list of the master, setting the number of I/O words

according to parameter P0727.
If everything is correctly configured, the OP LED of the module will be on in green. It is in this condition that
cyclic data exchange effectively occurs between the drive and the master of the network.
NOTE!
In the configuration software of the Profibus network, first you must select all the input words (
