Please bear with me.... bit of a newb when it comes to all this... I have a PMDX-107 + PMDX-126 + ESS connected to Huanyang HY02D223B.

The test button on PMDX-107 starts the spindle turning and gives me 10.5v on 1st press and 3.47 on 2nd(on pins 1->2.) The VFD/Spindle goes to 400(max speed) regardless of voltage.
Can someone put me on the right path??? I don't mind reading but cant seem to find a good primer or anything related to my specific issue.
Thanks!

After reading what others have done I setup everything as follows:

PMDX-107 to VFD
Pin 6 - Rev/Dir - REV
Pin 5 - Fwd/Run - FOR
Pin 4 - COM - DCM
Pin 3 - Not used
Pin 2 - Aout - VI
Pin 1 - Agnd - ACM

PMDX-107 Config settings (dip switches)
Config 1 = Off (Normal Mode)
Config 2 = Off (Normal Mode)
Config 3 = Off
Config 4 = Off (charge pump signal required)
Slow = Off
5v/10v = Off (10v reference)

PMDX-126 Settings
Config 1 = Open
Config 2 = Closed
Config 3 = Closed
Config 4 = Closed
Config 5 = Closed
Config 6 = Closed
Config 7 = Closed
Config 8 = Closed


Changed PD001 Source of Run Commands to '1'
If PD002 is set to 0 unit runs at 400, if set to 1 it goes to minimum (119.9)
Changed PD005 Max operating frequency to 400hz
Changed PD004 base frequency to 400hz
Changed PD003 Main frequency to 400hz
Changed PD006 Intermediate frequency to 2.5
Changed PD008 max voltage to 220v
Changed PD009 Intermediate voltage to 15v
Changed PD010 Min voltage to 8
Changed PD011 frequency lower limit to >119.9hz (so I can see when it is just delivering Minimum)
Changed PD142 rated motor current to 11

Posting for posterity. The answer was provided by another user in another forum...
PD072 Higher Analog Frequency - Needed to be set to 400 and WAS on the default of 50.
