[SOLVED] MesaCT problems with 7i96 pwm spindle

Does that potentiometer on the PWM --> Analog module adjust the scale?

it does adjust the output voltage a bit, but not the scale i dont think.

so here are some numbers when its working

mesa - 5.2v
pwm module - 12.1v in
m3 s12000 (min) - 2.34v in (2.53 unplugged) 4.92v out
m3 s24000 (max) 4.65/5.07(u) 8.62 out

if i step up the input voltage to 14.2v i get 9.77@24k and 5.24@12k

if i adjust the pot on it i can get 10v but only at 14v. i max out at 8.65 @12v. but when i get 10v, im at 5.78 on the low end which i suppose wouldnt be all that bad with an air cooled spindle vs going too slow

ok so i for the most part got it working now, thanks jt pete and tom for the help! basically if i run the pwm module at 14v i get close enough to 5-10v to give me 12-24k rpm.
the last thing i just need to figure out is how to get the spindle to actually start. been trying to decipher a chinglish manual all afternoon to program this vfd. to be fair tho, it is actually better translated than the other ones ive dealt with. i can set the working frequency from linuxcnc but cant actually get it to start remotely. if anybody has any experience with a huanyang fc01, any help would be greatly appreciated!

Pictures of your VFD connectors?
Not from the net, last week i dealt with two of the same make and model VFD that are not the same in any way, nor are the electronics the same.

ok so heres a pic of the conns. i have verified everything all the way up to them is working. spindle start is on ssr.03, and all the wiring from the mesa to the vfd is tested. as best as i can tell P00.01 should switch between the keypad and remote switching. i can change the frequency from linuxcnc but thats about all. 

the manual is here: www.huanyangvfd.com/wp-content/uploads/2.../FC01-Series-VFD.pdf
