Nice drawings Jim, here's what I see;

1. Pin 6 of PMDX-107 should go to VFD ACN (ACM ?) (GRD) terminal.
2. Why is there a switch in the PILZ terminal A1 supply ? it's not normal.
3. Can the PILZ relay contacts handle the VFD supply current ?
4. Can the PILZ relay contacts handle the 70V PSU input current ?
