Trying to set up position control mode

Hi all,

We are working on a retrofit of an older Fryer lathe. We are using a Mesa 7i95 board and are trying to connect our SGDH-10AE Yaskawa drivers to the board in position control mode. We have managed to make the axes move in what seems like position control, but when changing the jog speed in AXIS, it also changes where the motion stops. I believe that I have made a mistake, or many, in trying to set up our HAL code. We generated the HAL code from Pnfconf and then made adjustments to try to change the Stepgen to position control mode. I was hoping that we could get some help in looking at our Hal and Ini files to see where we may have gone wrong. Or if someone has successfully implemented it, we could look at their files to see if we can figure it out. 

Thanks!

I suspect interference, so pictures of the wiring from Mesa to drives might help.

Why are there two posts with the same hardware and same issues by two members?
Are you the same team?
If yes, continue here.
Thank you.

Yes, we are the same team. I have attached photos. We have also looked at the signals from an oscilloscope and are getting nice clear step waves.

Thanks for the quick reply!

Check at the drive side.

I checked on the drive side and it looks clean as well.

The wiring does not look right to me, Don't those drives have differential inputs?

If they are differential, the 7I95 Step/Dir connections are wrong.
