Shutting down sequence has been
1 computer
2 power supply to panel
3 All power inc vfd
I have a spur which supplies the no volt relay to the Control panel, but separately supplies the 5 v PSU for the BOB. Will try taking its supply via the NVR.
Problem only became apparent when I added spindle control . BOB relay is only switching a 24v signal to the VFD
