vfd query about the program settings for XSY-AT1 and air cooled spindle

[marbles]

Apologies for the silence been in the Cairngorms!

I bought it because its dimensional height meant it would fit in my control box. It has a manual (of sorts) Here’s a scanned page with some of the key perameters to set.

If the Huanyang would fit in my control box I would have bought one.

From the looks of that you need to set
Maximum Operating to 400 and
Minimum Operating to the correct percentage of 400 to give your spindle's rated minimum speed.
Reference Speed to 400 and
Intermediate Speed to halfway between 400 and minimum rated speed

thanks thats very useful information.

I have virtually the same setup as you but just cant get the spindle to run with any consistency. The spindle starts and slowly builds up speed but stutters and then trips out on Err 1 (Short circuit/Current overload/Power module protection). I have tried numerous combination of settings to no success. I assume you have your system running and would be grateful if you or others can point me in the right direction.

Sounds familiar . I'm not near the cnc till tomorrow but can paste the P1-P8 VFD settings, which might be of use.

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.

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.
