Thanks very much. I have subsequently connected and programmed a Teco VFD I have, but getting the same results coming out "inverter overload". I think I am doing something fundamentally wrong and keep going over the programming options to try and discover. I have an clamp meter attached and abort the start-up very quickly as current way over the spindle rating. All help much appreciated.
Re: vfd query about the program settings for XSY-AT1 and air cooled spindle
After a bit of trial and error I have the spindle running although clarification would be good on what the intermediate frequency does.
P00. 220
P01. 400
P02 15
P03. 200. Changing this from 25 up to 200 resolved the matter. Not happy at 100 but ok at 300. Spindle starts to rotate when this value reached.
P04. 0
P05. 0
P06 400
P07. 0
P78. 8000
Be interested to see how your values compare.
It suggests to me that the VFD is defaulted for a 3ph 50 Hz motor and once you come away from that various other factors come into play.

Im running a small surface grinder on one of these and cant seem to get the power id expect. Ive been looking for the current limit. Any idea where it is?
Re: vfd query about the program settings for XSY-AT1 and air cooled spindle
I am absolutely no expert and hopefully somebody can assist. Not sure what you mean you are not getting the power you expect. You have set P78 to the rating of your grinder?
Re: vfd query about the program settings for XSY-AT1 and air cooled spindle
It's set as when I got it at 8000 but I'm not sure what it's 8000 of? My grinder has a rating in amps and it certainly isn't 8000 amps. Is this milliamps?

Re: vfd query about the program settings for XSY-AT1 and air cooled spindle
In which case its set far too high. I'll set it to the correct rating. I feel it may be something else then. Is there a pole count setup?

Hi,
For anyone looking for a known set of working parameters/settings for the XSY-AT1 VFD, George (tarawa) has posted back his settings that worked for him, the link to this info is below:
