Only one problem as best I can see.
The Aref of the PMDX-107 should connect to terminal 10, "Power supply terminal for
frequency setting" on the VFD.
The fault output terminals can be ignored, or if desired you can configure them in
the VFD and connect to the /Fault input on the PMDX-126. The PMDX-126 fault
input triggers an E-Stop and based on my quick reading of the VFD manual, none of
the options in the VFD seem like candidates to request an E-Stop.
