6 Error messages
Errors cause the frequency inverters to switch off, in order to prevent a device fault.
The following options are available to reset a fault (acknowledge):
1. Switching the mains off and on again,
2. By an appropriately programmed digital input (P420 = Function 12),
3. By switching of the “enable” on the frequency inverter to Low (if no digital input is programmed for
acknowledgement),
4. By Bus acknowledgement or
5. By P506, the automatic error acknowledgement.
Device LEDs:
As supplied, various LEDs (green/red/yellow) are externally visible. These indicate the
actual status of the device (Section 4.2 /4.3)
FI / DS LED:
This LED (Section 4.3) is dual-colour and can therefore indicate both a ready or an error
status of the FI.
Green
indicates the standby status and the presence of mains voltage. During operation
an increasingly rapid flashing code indicates the degree of overload of the FI output.
Red
indicates the presence of an error by flashing with a frequency which corresponds to
the number code of the fault (Section. 6.2).
6.1 SimpleBox display
The
SimpleBox
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 the FI
status when errors occur 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 OK key.
