PMDX-106, PMDX-122, Huanyang VFD setup)

[Bob at PMDX]

Here are some things to try:

(1) Can you control the spindle from the VFD front panel?

(2) There is usually a register that determines where the VFD looks for control info.  There are usually values for "front panel" or "internal", something like "Analog" or "0-10V" or "Fwd/Rev" or "external", and sometimes "RS-422" or "MODBus" if your VFD supports those interfaces.  See if you can find that register or registers.  In the example from jbolt above, those look to be PD000 and PD001.  See also the comment in this thread by Steve on July 19th, 2015 about a jumper inside the VFD that you may need to change.

Once you verify that you can control the VFD from the front panel, and then change the registers so that the VFD is looking at the 0-10V analog input and the Fwd/Rev terminals, go on to try this:

I presume you have a PMDX-126 along with the PMDX-107.  Is that correct?  Have you looked at our app note AN001, "Mach3 Configuration with 3 Axis and PWM Spindle Speed Using a Single Parallel Port" (http://www.pmdx.com/AppNotes)?  Even if you are using Mach4, that app note will give you the necessary PMDX-126 and PMDX-107 DIP switch settings.  And if you are using Mach3, it also gives you the Mach3 settings to make sure the spindle PWM signal appears on the correct pin.

If you are using Mach4, what motion control device/plug-in are you using?  If you are using Mach3, are you using a PC parallel port to connect to the PMDX-126?  Or are you using an external motion controller such as a SmoothStepper?

(3) Make sure you have the spindle PWM signal assigned to Port 1 Pin 16, and the spindle direction signal to Port 1 Pin 14.

(4) If your settings are correct, when you command the spindle on, with a non-zero speed, you should see the LED on the PMDX-126 at connector J6, the terminal labeled "16" turn on, as well as the "PWM" LED on the PMDX-107.  The brightness of those LEDs should vary with spindle speed - the higher the spindle speed, the brighter the LED.

(5) When you turn on the spindle in the forward direction (i.e. with an "M3" command), you should see the "Run/Fwd" LED on the PMDX-107 turn on.

If you do not see the expected results for steps (4) and (5), then we need to investigate your Mach3/Mach4/Motion Controller configuration.

I too looked for information on your model of Huanyang VFD. I was
able to find places offering it for sale, but could not find a manual.

If it is like other Huanyang VFDs, the parameters that control the
source of commands are:

PD001 run command source
            set to 0 for operator panel on the VFD
                      1 for terminal strip, this is what you need
                      2 for communications port

PD002 source of operating speed
            set to 0 for operator panel on the VFD
                      1 for terminal strip, this is what you need
                      2 for communications port
