Parameter list
For detailed information on coding and access attributes of all parameters, refer to the
parameter list.
Incorrect service
execution
The service was performed by the inverter if the received handshake bit is the same as
the sent handshake bit.
Return codes for
parameter setting
In the event of an incorrect parameterization, the frequency inverter sends back various
return codes to the parameterized master. These codes provide detailed information
about the cause for the error. All of these return codes are structured in accordance with
EN 50170. The inverter distinguishes between the following elements:
• Error class
• Error code
• Additional code
These return codes apply to all MOVITRAC
®
B communication interfaces.
Error class
The error class element provides a more exact classification of the error type. The fol-
lowing error classes are distinguished in accordance with EN 50170.
The error class is generated by the communication software of the fieldbus interface if
there is an error in communication. This statement does not apply to
Error class 8 =
Other error
. Return codes sent from the frequency inverter system are all included in
Error class 8 = other error
. The error can be identified more precisely using the additional
code element. The Ethernet error code is "0".
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 inter-
face in the event of faulty communication.
