Thanks gents for the welcome. I've got a few books and am working my way through YouTube videos. Such a lot to learn!! Didn't realise what I was letting myself into.

I'm into restoring classic motorcycles, have a 1939 and 1942 Ariel, 51 triumph and a BSA Bantam. The reason for the lathe is to make parts for these. Just got a 1952 Ariel project that needs some love so the lathe will come in handy there.

Thanks for the input gents. It was par 73 that was wrong. Was 61440 not 31440. Changing this to the default 31440 cured the issue. Vfd was set like that when I bought it so maybe there's a batch out there set up wrong. Hopefully this post may help others in the future

Hope someone can help. Have a myford 7 with an at1 vfd and 3 phase motor. Speed/frequency set to 50htz and runs up to that using the pot on the at1. Have wired an 10khm ext pot and set it to run from that. Wired to com and the 5v terminal on at1 and the pot centre wiper to vl1.

External pot works fine but max frequency only 25htz. Any ideas?

When I bridge the pot to give full output to vl1 still 25htz....it's as though the at1 wants 10v from ext pot but I can't see anyway if increasing the 5v from the at1 board.

Help / advice please.

If anyone has an at1 it would be helpful if you could tell me you voltage between the voltage output and com on the right hand end of the gree terminal block (the connection used for an external pot)

Thanks..Alan

Hi, I'm Alan Moore from Leicestershire. I have recently got myself a 1972 ml7. Having no lathe experience I have been looking at posts on the forum for some time. I have fitted an at1 vfd and. 1 hp 3 phase motor. Striped the lathe down completely, repainted and built it back up. Fitted a tachometer and got together some tooling and other bits and pieces. I am close to Turing my first chips and will no doubt be asking some questions soon.
