No problem.

Been doing a little more reading, looks like PD007 and PD010 work together to define the minimum point on the V/F curve, so in essence it looks like its a way to tune how much torque you get from the spindle at different speeds? Either way, 0.5 or 1.2 should work to get you started.

It might just be paranoia, but when I turned on my spindle I had a second person around who knew how to isolate the power supply. Just incase I'd messed up one of those phases and was about to make the whole thing a bit sparky. I then checked the spindle body with a multimeter while it was running, and sheepishly tapped it with the back of my hand to make sure all was well.
