The work continues...
Wiring up the induction motors for the spindle and hydraulic pump into the VFDs. The phase connections are totally enclosed in flexible steel conduits - up until the last few inches. And as mentioned, the VFD supply sides both have EMC filters, so should be reasonably quiet, electrically speaking. Note also the red braking resistor for the spindle. There's no need for one on the hydraulic pump, obviously.
Now a mounting plate for the servo drivers. This mounts on the rear face of the headstock where it's away from any coolant and swarf. I've used nutserts both to provide threaded inserts to mount the drivers to the plate and also as through spacers to mount the plate to the headstock (M5 nutserts in the plate with M4 screws through to the headstock etc). Seems to work well.
Here are the 2 servo drivers temporarily mounted in place, with their EMC filter between them. Looks workable but lots of wiring still needed to connect it all up.
