Alarms, faults and system messages
9
The converter has the following diagnostic types:
●
LED
The LED at the front of the converter immediately informs you about the most important
converter states right at the converter.
●
Alarms and faults
The converter signals alarms and faults via the fieldbus, the terminal strip (when
appropriately set), on a connected operator panel or STARTER.
Alarms and faults have a unique number.
If the converter no longer responds
Due to faulty parameter settings, e.g. by loading a defective file from the memory card, the
converter can adopt the following condition:
●
The motor is switched off.
●
You cannot communicate with the converter, either via the Operator Panel or other
interfaces.
In this event proceed as follows:
●
Remove the memory card if one is inserted in the converter.
●
Repeat the power on reset until the converter outputs fault F01018:
–
Switch off the converter supply voltage.
–
Wait until all LEDs on the converter go dark. Now switch on the converter supply
voltage again.
●
If the converter signals fault F01018, repeat the power on reset one more time.
●
The converter must now have been restored to its factory settings.
●
Recommission the converter.
