STARTUP GUIDE

The following are the main steps for commissioning of CFW11 frequency inverter on the EtherCAT network. The
steps are an example of usage. Refer to specific chapters for details on the steps.
9.1

INSTALLING THE ETHERCAT MODULE

1. Install the EtherCAT communication module, as indicated in the installation guide that came with the module.
2. Connect the Ethernet cable to the module, considering the necessary care in network installation, as described
in section 4:
Use shielded cable.
Perform a properly grounding connection.
Avoid the passage of communication cables next to power cables.
9.2 CONFIGURING THE DRIVE
1. Follow the recommendations described in the user's guide to program the device parameter related to motor
parameters, desired functions for the I/O signs, etc.
2. Program the desired drive command sources to local and remote mode, to control via EtherCAT.
3. Set the desired device action in the event of communication failure, through P0313 (P0313 = 1 to cause
equipment failure in the event of loss of communication with the master).
4. Other settings, such as selection of data for communication via EtherCAT, are made by the configuration tool
of the network master.
9.3 CONFIGURING THE MASTER
The way you do the setup of the network depends largely on the master and configuration tool. It is important to
know the tools used to perform this activity. In general, the following steps are required to perform the network
configuration.
1. Load the XML configuration file provided on the CD shipped with the product
network configuration tool.
2. Select CFW11 frequency inverter on the list of available products in the network configuration tool. This can be
done manually or automatically, if allowed by the tool.
3. Program the transmit and receive PDOs, as well as the data transmitted and received by these PDOs:
There are 4 TxPDOs and 4 RxPDOs, but only one can be enabled at a time.
TxPDOs are associated with the Sync Manager 2 (outputs), while RxPDOs are associated with the Sync
Manager 3 (Inputs). The selection of which receive and transmit PDOs are active is done through objects
1C12h and 1C13 respectively.
Each PDO has a default mapping containing a set of predetermined objects for communication. This default
mapping is usually sufficient to meet most applications, but you can change the mapping if desired.
4. You must also set the data update cycle. The minimum value supported by the device is 1ms.
5. The equipment allows the master to use two interrupt modes for data update:
Without synchronized interrupt (SM-Synchron): for each EtherCAT telegram received, an interrupt is
generated to update the data process.

It is important to note if the XML configuration file is compatible with CFW11 frequency inverter firmware version.
