7i76e and 2.2Kw spindle connection help

PCW, I had to call my friend to find out the voltage we were getting to the spindle because I could not remember...He says it was measured at 8.6V...I believe we understand how the voltage scale is setup and working at this time...
My friend has suggested that we add to the spindle.hal commands "motion.xxx" which are not presently included in any of our hal syntax...

pncconf will set up all the spindle connections. I would update LinuxCNC to the latest
release version (2.8.1) and re-run pncconf

If you do not reach tge expected voltage:
I remember somebody had the problem that the potentiometer was in parallel to the vfd bornes. He had to take out a jumper...

PCW, The machine is already running version 8.1...We worked on machine for a couple hours today...Testing shows that my report of 8.6 volts was incorrect, we are actually seeing 9.6 V at the VFD...With the command line in Show Hal Configuration it was determined that the RMP's are almost linear from 2000 to 19000 RPM...The spindle can be started and stopped from the Axis interface buttons and MDI commands M3 & M5...But we are still unable to increase and decrease the RPM through Axis interface or MDI...We have diligently searched and compared examples of hal and ini files for the hal pin/command that allows us to send a commanded voltage/RPM to the spindle and come up without a clue...The spindle is stuck on whatever voltage/RPM that it is getting...I am guessing that when we get it working that the answer will be something stupidly silly...I have run the PNCConf twice before to no avail, but will run it again...

@Mike_Eitel, Mike, we can live with the voltage we are presently getting (9.6+V)...I talked with my friend and he assured me that we are only running the 7i76e potentiomer, but I am going to do more research...

Thank you both for your input...

Mike

Can you post your current hal and ini files?

PCW, I sure can post them...

Thanks
Mike
