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.
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.
