10.7 If the converter no longer responds
If the converter no longer responds
For example, when loading an incorrect 󹪝le from the memory card, the converter can go into a
state where it can no longer respond to commands from the operator panel or from a higher-
level control system. In this case, you must reset the converter to its factory setting and
recommission it. This converter state is manifested in two di󹪜erent ways:
Case 1
• The motor is switched o󹪜.
• You cannot communicate with the converter, either via the operator panel or other
interfaces.
• The LEDs 󹪞icker and after 3 minutes the converter has still not powered up.
Procedure
1. Remove the memory card if one is inserted in the converter.
2. Switch o󹪜 the converter power supply.
3. Wait until all LEDs on the converter are dark. Then switch on the converter power supply
again.
4. Repeat steps 2 and 3 as often as required until the converter outputs fault F01018.
5. Set p0971=1.
6. Switch o󹪜 the converter power supply.
7. Wait until all LEDs on the converter are dark. Then switch on the converter power supply
again.
The converter now powers up with the factory settings.
8. Recommission the converter.
You have restored the converter factory settings.
❒
Case 2
• The motor is switched o󹪜.
• You cannot communicate with the converter, either via the operator panel or other
interfaces.
• The LEDs 󹪞ash and are dark - this process is continually repeated.
Procedure
1. Remove the memory card if one is inserted in the converter.
2. Switch o󹪜 the converter power supply.
3. Wait until all LEDs on the converter are dark. Then switch on the converter power supply
again.
4. Wait until the LEDs 󹪞ash orange.
