Return codes of
parameter setting
In the event of an incorrect parameter setting, the inverter sends back various return
codes to the master which set the parameters. These codes provide detailed information
about what caused the error. All of these return codes are structured in accordance with
IEC 61158. The inverter distinguishes between the following elements:
•
Error class
•
Error code
•
Additional code
These return codes apply to all MOVIDRIVE
®
communication interfaces.
Error class
The error class element provides a more exact classification of the error type. In
accordance with IEC 61158, the system differentiates between the error classes listed
in table 1.
Except for error class 8 = other error, the error class is generated by the communications
software of the fieldbus card in case of a faulty communication. Return codes sent from
the inverter system are all in Error class 8 = Other error. The error can be identified more
precisely using the additional code element.
Error code
The error code element allows for a more detailed identification of the error cause within
the error class and is generated by the communications software of the fieldbus card in
case of a faulty communication. For error class 8 = other error, only error code = 0 (other
error code) is defined. In this case, detailed identification is available in the additional
code.
