Lenze VFD

Dear All,
I have a stitching machine which use Lenze VFD that suddenly stop and could not run again. There is a message on operator screen saying: Fault Frequency Inverter. I could not find any part number/model on the unit but brand name is Lenze. On the operator manual book, there is a sentence saying that this VFD is maintenance free and brand name is Lenze Series 8210.
I googling Lenze Series 8210 and found one but the picture is different. Also the terminal wiring is different as well.
I appreciate if somebody would give me a hand.
Thanks.

This is probably something you should talk to Lenze about. That’s an older discontinued product line.

Dear Jraef,
I will talk to Lenze, I appreciate to your response.

The Lenze nameplate with all the specs is behind the removable IO Module.


Remove the screw over the X2 & X3 jumper banks and pull it straight off.


I work on quite a few machines with Lenze's and have had good luck on Ebay finding replacements

Dear Aabeck,
Thank you for the response, I will check it out when going back to work.
