I need a littler help please. Mr moderator, if this is in the wrong section would you please move it to the correct section, thank you.
I screwed up my settings om my FR-D720 Mitsubishi Frequency drive.

I'm using a Chinese spindle motor 200730184245.5 rated at 8amps, 400Hz, 220V, 2pole,24,000RPM,

Can anyone remind me of the FR-D720 parameter settings for this motor please.Please be aware I'm running the inverter in MON mode (Manual)

I cannot seem to get top speed of 24000 RPM any more. It's been working fine for over 10 years. I should not have played around with the settings, I did an All Clear function and a Factory reset function.

I have uploaded the documentation, I'm sure I had put the parameters back to where they were but it's still not right. If anyone can help I

My Parameters are set as follows:- If any one would like to compare these with those on page 54 & 56 of the manual I would be extremely grateful.
