Thanks for the link and there are two things that you need to get any VFD working:

1. You need to setup the parameters so that the VFD takes 0-10v, CW and CCW signals.
   
2. You will need to wire the 0-10v, CW and CCW signals to MASSO.
   

So now do you have any experience with any of the above or need help on both?

Can I also get your MASSO controller serial number.

Serial No. 5A-2184

and yes i need help with all

Thanks and will start compiling some information for you. As we dont have the VFD, you will need to do the test and we will try to provide the best information we can from the drive manual.

In the time being please watch this video because we discuss some points on how to get started on a VFD setup

See the attached file and you can do the connections like this, please make sure that you check everything as we can only guide as per the manual and there can be mistakes, so please read the VFD manual carefully.

I have successfully wired up the drive ( CM1 should be P24) ,Thank you .But i am having trouble with running the mill wizard its not correctly generating the code ,the final measurement are a little off

and i have calibrated and checked the machine movements and they are correct .

I have also been able to get fusion 360 to generate the post apparently its working fine ,however the machine its not kipping up with the positioning.

And the controller its out of sink with reality because its a open loop system ,can this be addressed ?

I am using Gecko G320x dc drives

Thanks

It looks like you are missing steps on the motors due to high feedrate or acceleration. The right way to fix this is to make the max feedrate for each axis and acceleration settings smaller than what you have. Then you have to try to machine till the point where you think that the steps are not missing anymore.
