6.2.2

Automatic device identification

For a faultless integration of the EtherCAT slaves into a master configuration it is necessary to select

the correct Lenze device in the EtherCAT configuration software.
Each EtherCAT node is identified unambiguously by the configuration software by means of the

product code (equal to the CoE object I-1018.2), the manufacturer's identification mark (0x3B), and

the main software version of the communication module.

Identification

( 12)

Implemented CoE objects

( 79)

In order that the configuration software select the configuration from the device description file

specific for the EtherCAT node, the product code is automatically set in the identity object. An

update is made after switching off/on the voltage supply.
During initialisation, the product code is transferred to the EtherCAT master. On the basis of this

identification, the master can accept the corresponding settings from the device description.

Product codes for Inverter Drives 8400
The product code defines the following Inverter Drives 8400 in the device description files:

6.2.3

Configuring process data

Inverter Drives 8400 support the configuration of max. 16 process data words (max. 32 bytes) per

direction.
The process data configuration is determined during the initialisation phase of the master (PDO

mapping).
The process data configuration is predefined in the device description file for each application.
The process data length can be adjusted by the user if required.

6.2.4

Determining the cycle time

The process data objects (PDO) are transferred cyclically between the EtherCAT master and the

slaves (inverters).
The cycle time is set with the EtherCAT configuration software.
