A lot of people are posting the settings they are using in the Huanyang VFDs, but I would like a definition of a couple of them. I am reading the information in the manual, but I’m not an electrician and don’t really understand what I’m reading. In layman’s terms could some one please explain parameters PD071, 72 and 73?  I am trying to adjust my spindle speed from Mach to the VFD. I am bringing in 0-10v from the BOB to the VFD, but I am only really getting 8.65v at the top end. I was wondering if any of these settings could have an effect on the input voltage.
Any info would be appreciated.

Thanks,
Jim
