Disconected the shielding on the signal cable to the Vfd. Well What can i say, it works now!!
When i was testing yesterday i got to a multiplier at ,00276. I works really nice now when i disconected the shielding.

Thank you for the help!

It's just a normal spindle so no gear or anything. I have had it at one all the time.
But something feels wrong when the Hz change. It looks to work perfect when the spindle is off. 9000rpm is nearly perfect on 150hz at the Vfd and 18k is at 300hz but as soon i turn the spindle on at 9000rpm it goes up to 180-190hz??

Don't know if it's a setting in the Vfd? Running a delta E series Vfd.

What should the settings be in mach port and pins page? Base freq and minimum pwm??

thanks for all the help!

Nevermind!

I fixed it!!!!!!! 

Now it runs cleanly from 4000rpm in mach and all the way up to max!

I got it to start working sort of. My spindle goes up to 300hz and 18000 rpm but i only managed to get IT working from 87hz when i put in 5000rpm in mach3. When i put in 4000rpm the Hz goes up and not down but i gues i can live with it. The machine is for wood routing so Don't need to go so slow.

But i still have a problem. I get a maximum at 290hz but when the spindle turns on it drops to 225hz. And when i set it to 5000rpm in mach it only goes down to 160hz insted of 87hz it does when the spindle is on?? It's like the Vfd draws to much current or what is going on?

Hello!

I'm in the process to setup a pokeys57cnc but i got really stuck. I'm trying to setup the 0-10v output for the Vfd but got nowhere.
I have read the manuals but can't really work It out. I got one relay working as spindle on but the rpm output nothing happens. Can someone get me some Steps to get me in the right direction??
