Good day everyone! It's been several weeks of working very hard to complete my Mill Retrofit. The AjaxCNC is installed, test, and nearly configured!!!! Big job, fun job, learned a ton!

I took the 3hp Huanyang from my BP grinder for the Mill install. It works fine except for the use of the AI or VI inputs. When set correctly, the AI (4 modes... 0 = 0-10v, 1= 0-5v, 2= 0-20ma 3= 4-20ma 4= stacked 4-20 & 0-10v) should take the input voltage upon the ACM and AI pins and adjust the running FREQ setting. This voltage is developed from my DC-AIO DAC outputs for spindle variable speed.

I have tried the input on the AI setup AND tried the VI input pin. My setups are:
Pd002 = 1 exterm. terminals.
Pd003 = 0 or 60... depending on which mode. I've left at 60 for now to get the motor to spin.
Pd0070 Tried as 1,2,3,4 With the setting of 3 or 4..... IT will run, but only 60Hz, Does not vary w/ voltage in. (again just trying to experiment a bit).
I have tried the J1:2:3 jumper on both J1/2 and J2/3 No diff.
The FWD, REV, and RST all seem to work fine w/ PD44,45,46 setup as 2,3,14
PD0052 is set to 03. The NO relay will close on a fault. (Fa / Fb /Fc)

As near as I can tell this is setup correctly? Anyone have any luck here? I'm digging thru a slew of posts here- Will report back w/ findings. Went thru a dozen posts. Most relate to using a 10K pot to change the speed. Starting to wonder if I need that 10k pot installed just to use the AI input?

Hi,

I just changed PD002 to 1 (terminals) and set the jumper to 1,2
I used a little circuit to convert my Smoothieboards 3.3V PWM into a 0-10V analog signal and it worked fine for me.
The Run command was given via the operator panel and the analog signal was connected to VI.

This is my circuit

Did you check the PD 72/73 settings for the Low (ov) and the High (10V). That was my issue. Once I changed them I had no issues. It's a slick little VFD for the price.
