Dears,
Hi
kindly I need Mitsubishi FR-A840-00126-1-N6 VFD firmware dump for primary and secondary flash memories, thanks in advanced.

 

Dears any support or suggestions?

 

Hi,
Yes, I never mind to buy, kindly send me the details and cost.

 

I don't know if it's right, but I went to Mitsubishi's website, logged in, and searched for firmware. Filtered on inverters:

The 2nd hit looks like it's for the A800 drives. Again, though, I don't know if it's the right file. I would reach out to Mitsubishi for support.

 

Have you tried contacting Mitsubishi Electric's technical support or an authorized service center? They may be able to provide the correct firmware files or advise on the recovery procedure for that specific FR-A840 model.

I'd be a bit careful about using a firmware dump from another drive, even if the model number is the same, since hardware revisions and firmware versions can differ. It would be worth checking the exact hardware revision and firmware version before attempting to write anything to either flash memory.

Hopefully someone with experience repairing FR-A800 drives can point you toward a reliable source.
