7 Status messages
BU 0180 GB-0914 Pre-series version 141
7.1 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 current 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.
