PROTOCOL-SPECIFIC INFORMATION
9.11.3 Transmit and Receive Process Data Word Settings
In the studio’s Project panel, navigate to A7NETH-2P…Ethernet…EtherCAT…Transmit Process
Data…Transmit Data Word and/or Receive Process Data… Receive Data Word.
The Produced Data Word objects define the structure of status data sent from the inverter to the master.
The Consumed Data Word objects will define the structure of the command data sent from the master
(for example, a TwinCAT PC) to the inverter. These objects allow the creation of custom-built I/O
process data. Up to 32 “command” register values can be sent to the inverter, and up to 32 “status”
register values can be sent back to the controller. Therefore, up to 32 Transmit and 32 Receive Data
Word objects can be created. The I/O process data format is summarized in Table 59.

(Inverter to Master)
The default I/O configuration is described in Table 60. Always use the studio to confirm the configuration
before commissioning the device.
