6 Error messages
Errors can cause the frequency inverter to switch off.
The following options are available to reset a malfunction (acknowledge):
1. By switching mains off and on again,
2. By an appropriately programmed digital input (P420 ... P425 = Function 12),
3. by removing the "enable" at the FI (if no
digital input is programmed for acknowledgement),
4. By Bus acknowledgement or
5. by P506, the automatic error acknowledgement.
6.1 ControlBox displays (option)
The ControlBox (option) displays an error with its number and the prefix "E". In addition, the actual error is
displayed in parameter P700. The last error messages are stored in parameter P701. Further information
on inverter status when errors occur can be found in parameters P702 to P706.
If the cause of the error is no longer present, the error display in the ControlBox flashes and the error can
be acknowledged with the Enter key.
6.2 ParameterBox displays (option)
The ParameterBox (option) displays an error in plain text. In addition, the actual error is displayed in
parameter P700. The last error messages are stored in parameter P701. Further information on frequency
inverter status when errors occur can be found in parameters P702 to P706.
If the cause of the error is no longer present, the error can be acknowledged with the Enter key.
