6.4 Parameterization return codes
6.4.1 Elements
In the event of an incorrect parameterization, the inverter sends back various return
codes to the parameterized master. These codes provide detailed information about the
cause for the error. Generally, these return codes are structured according to the follow-
ing elements.
• Error class
• Error code
• Additional code
6.4.2 Error class
The error class element (1 byte) provides a more exact classification of the error type.
6.4.3 Error code
The error code element (1 Byte) allows for a more detailed identification of the error
cause within the error class. For Error class 8 = Other error, only Error code = 0 (Other
error code) is defined. In this case, detailed identification is made using the additional
code.
6.4.4 Additional code
The additional code (2 bytes) includes the detailed error description.
