Mesa StepGen ouputs with Yaskawa servos

Thanks for the explanation.
I'll keep investigating and probing.

Hi

I am planning to use Yaskawa sgd7s with a mesa 7176e. Did you find a solution for the lost steps? Best jannik, Switzerland

Hi Jannik,

If I remember correctly the problem ended up being a faulty servo driver. My Mesa/Yaskawa combination has been working fine for some time now.

Johnbl,

I am working on a lathe with SGDH-10AE drives and a Mesa 7i95 using step and direction with position control on the drive. Would you be willing to supply your hal, ini files from Linuxcnc and your parameter files from your drive?

We have some control over the drives and have the step and direction wired up as suggested here. Our linuxcnc is not working as we would like and the drive isn't producing consistent results. I think the pulses are coming out of the 7i95 too quickly. we do have some level of speed control through jog limit, but not what we would like and for some reason we don't get consistent distances depending on speed. We are having to tune the drive for position control which I thought would not be required initially. We aren't using feedback to the mesa, only internal to the drive.

Thanks,

Howard

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