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 an error (acknowledge):
1. Switching the mains off and on again,
2. By an appropriately programmed digital input (P420 ... P425 / P470 = Function 12),
3. By switching of the “enable” on the frequency inverter (if no digital input is programmed for
acknowledgement),
4. By Bus acknowledgement or
5. by P506, automatic error acknowledgement.
Device LEDs:
In the delivery condition (without technology unit) 2 LEDs (green/red) are visible externally.
These indicate the current status of the device.
The
green LED
indicates that the mains voltage is present and operational, while a flashing
code that increases in speed shows the degree of overload at the frequency inverter output.
The red LED signals actual error by flashing with a frequency which corresponds to the
number code of the error (Section. 6.2).
6.1 SimpleBox / ControlBox display
The
SimpleBox
or
ControlBox
display 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 / P799.
If the cause of the error is no longer present, the error display in the SimpleBox/ControlBox flashes and the
error can be acknowledged with the Enter key.
