7i92t and 5 axis bob no 0-10v on spindle

I definitely overlooked the specs on the 7i92. I don't think with the 5 axis bob can do anything other than pwm. This vfd can not be run from pwm. So I probably need a pwm to anolog voltage converter board. Sorry for the confusion and thank you for helping me!

If anyone has any suggestions that would be awesome! I was wondering if I can just use an RC circuit to flatten the pwm. Although I think if that were possible people would be doing it. From what I've read the cheap pwm to 0-10v converters aren't linear. Maybe best option is a new vfd. At least linuxcnc can turn it on and off when needed.

The 5ABOB  takes PWM from the parallel port and converts is to an analog voltage
Your latest hal file is missing the PWM generator setup  and connections:

# ---PWM Generator signals/setup---

setp   [HMOT](CARD0).pwmgen.00.output-type 1
setp   [HMOT](CARD0).pwmgen.00.scale  [SPINDLE_0]OUTPUT_SCALE


net spindle-output      => [HMOT](CARD0).pwmgen.00.value
net spindle-enable      => [HMOT](CARD0).pwmgen.00.enable

In addition you probably need to lower the PWM frequency to get decent linearity:setp hm2_7i92.0.pwmgen.pwm_frequency 1000

I've just made those changes. linuxcnc starts without errors but still no speed control.

setp hm2_7i92.0.pwmgen.00.output-type 1
setp hm2_7i92.0.pwmgen.00.scale 24000

net spindle-output => hm2_7i92.0.pwmgen.00.value
net spindle-enable => hm2_7i92.0.pwmgen.00.enable

Start LinuxCNC, start the spindle at 1/2 speed (using MDI) and then
type this command in a terminal and post the results here:

halcmd show all spin

 

ok, this is what i get from terminal.
