Hello,
My current set up is using an analog output from the 7i77 connecting to the AI3 analog input on the GS3-2010 VFD. My problem is I have next to no control of my spindle, it's either on or off. I have the max rpm range on the VFD set to 2000rpm. I suspect the reason why I don't have any control is the scaling from LinuxCNC doesn't know max rpm. I have searched the PNCCONF and I don't know where to change this. Maybe this isn't my problem at all. Any help would be great!
Thanks,
Tosh

I don't know where to change it in Pncconf, but if you look in the HAL file for the related "scalemax" then that needs to be 2000 rpm too.

I have uploaded the files that I thought useful and where the changes need to be made. Do I need to just change the code or add some code to set the spindle max to 2000 rpm? My coding experience is next to none and not sure what I need to do.
Thanks,
Tosh

in your INI file, try changing this:
to this:
#********************
# Spindle
#********************
[SPINDLE_9]
OUTPUT_SCALE = .005
OUTPUT_MIN_LIMIT = -10.0
OUTPUT_MAX_LIMIT = 10.0to this:
#********************
# Spindle
#********************
[SPINDLE_9]
OUTPUT_SCALE = 2000
OUTPUT_MIN_LIMIT = -2000
OUTPUT_MAX_LIMIT = 2000
