7 STARTUP GUIDE
The main steps to start up the SSW900 soft-starter in EtherNet/IP network are described below. These steps
represent an example of use. Check out the specific chapters for details on the indicated steps.
7.1 INSTALLING THE ACCESSORY
1. Install the communication accessory, as indicated in the installation guide supplied with the accessory.
2. With the module installed, during the recognition stage, the MS and NS LEDs test routine will be performed.
After this stage, the MS LED must turn on in green.
3. Observe the content of parameter S5.5.1. Check if the module was recognized. The detection is done
automatically and does not require the user’s intervention.
4. Connect the cables, considering the recommended instructions in network installation, as described in item 3.5:
Use shielded cable.
Properly ground network equipment.
Avoid laying communication cables next to power cables.
7.2 CONFIGURING THE EQUIPMENT
1. Follow the recommendations described in the user manual to program the device parameters related to the
motor parameterization, desired functions for the I/O signals, etc.
2. Program the command sources as desired for the application in menu C3.
3. Configure communication parameters, such as DHCP, IP address, communication rate, etc. in C8.3.
4. Program the desired action for the equipment in case of communication fault in C8.3.10.
5. Define which data will be read and written at soft-starter SSW900 using menu C8.1. Among the main
parameters that can be used to control the device, we can mention:
S5.1.1 Status Word SSW (read).
S5.2.5 Command Word Slot1 (write).
S5.2.6 Command Word Slot2 (write).
6. Once the parameters are set, if any of the parameters described in the previous steps were changed, the
equipment must be powered off and on again, or an update must be performed by C8.3.1.
7.3 CONFIGURING THE MASTER
The way the network configuration is done depends greatly on the used client and the configuration tool. It is essential
to know the tools used to perform this activity. In general, the following steps are necessary to perform the network
configuration.
1. Load the EDS file
to the list of devices in the network configuration tool.
2. Select SSW900 soft-starter from the available list of devices on the network configuration tool. This can be
done manually or automatically, if allowed by the tool. The EtherNet/IP module is described in the network as
“Generic Ethernet Module”.
3. For the master configuration, in addition to the IP address used by the EtherNet/IP module, you must indicate
the number of instances of I/O and the amount of data exchanged with the master in each instance. For the
communication module for EtherNet/IP, the following values must be programmed:

The EDS file is available from WEG website (http://www.weg.net). It is important to note if the EDS configuration file is compatible with the
firmware version of the SSW900 soft-starter.
