8i20/BLDC component, limited spindle speed

With Master you can set the params from HAL. But with 2.7 you need to use setsserial.

If speed limits are symmetrical and doubling the servo thread rate doesn't help dramatically, the problem
may be related to the current loop tuning, i think I would try setting the current loop P gain and I gain
to 1/2 of their default values , I think this requires setsserial or Mesa utilities a funny cable and Windows.

I am running 2.8 pre and I do recall using HAL to change current NV params on the 8i20. They seemed to be accepted but I don't believe they were persistent. I wound up using setserial which did work. It's been a couple months so I don't recall the details but is there anything special to get it working with just HAL?

I haven't tried setting the PID settings yet, I've been busy making parts with it, the motor runs well with the exception of being limited to 1900rpm stable spindle speed.

A couple of things, I'm not sure you can set NV params in hal
( and I dont think you would want to since you dont wont these constantly re-written
and NV params don't take effect until the 8I20 is power cycled )
You can set the volatile params in hal so any tuning can be done that way (or by setting the NV params outside of linuxcnc)

I VNC'd into the mill quick while it's fresh on my mind and I'm not sure I see how to make the PID adjustment. I started halrun with a test file that just loads up the basics so I can see pins and params. I only see pid-on and not pins, nothing I can see that a value can be read or write. There are a few that I have no Idea about though:

Ahh maybe the RAM parameter are not exposed so you would need to set the NV parameters (perhaps via setsserial) and then cycle the 8I20s low side power
I would try setting KQI,KQP,KDI,KDP to 1/2 of their current values

don't see a "KDI", or "KQI". there is a nvkdil and an nvkqil but there is also a nvkdilo and nvkdihi. am I changing everything of just the nvkdil and nvkqil?

There should be NVKQP, NVKDP, NVKQI, and NVKDI (the NVXIL parameters are integral limit numbers which can probably be left alone)

Are you sure that "nvkqil" is the limit? judging by the converted hex values it is likely that nvkqilo and nvkqihi are the limits. If you look at the read out parameters that I listed above there is no nvkqi. If I can't see it's current parameter I can't set it.
This is what I worked up, please look at this, I only intend to set the ones with an asterisk because the others look like the limits

I think either the parameters listed are missing the integral term or misnamed
that is nvkdqi and nvkdi are missing
Have you tried setting these (nvkdqi and nvkdi) with setsserial?
(take a look at the 8I20 manual for the proper parameter names)

Is there some way I can see their current values, or do you know the default? I don't want to write the parameter without knowing what to go back to. Otherwise I'm just guessing.
