SimpleBox - display
The SimpleBox displays an error with its number and the prefix "E". In addition, the current fault can
be displayed in array element [-01] of parameter (P700). The last error messages are stored in
parameter P701. Further information on inverter status at the time that the error occurs can be found
in parameters P702 to P706 / P799.
If the cause of the error is no longer present, the error display in the SimpleBox flashes and the error
can be acknowledged with the Enter key.
In contrast, warning messages are prefixed with "C" ("Cxxx") and cannot be acknowledged. They
disappear automatically when the reason for them is no longer present or the frequency inverter has
switched to the "Error" state. Display of the message is suppressed if the warning appears during
parameterisation.
The present warning message can be displayed in detail at any time in array element [-02] of
parameter (P700).
The reason for an existing disabled switch on cannot be displayed with the SimpleBox.
ParameterBox display
The ParameterBox displays the messages in plain text.
