Definately a scrapyard challenge

You've got the newer VFD. You'll find the 4mm collet that came with the spindle is not brilliant as it only has 6 slots. That causes it to not grip the cutter as firmly or concentrically as collets with more slots. Get a set of the collets on eBay which have more than 6...

Jonathan will probably know them straight off the top of his head.!

I do actually, since before I got the second one I used to change them a lot...this is what I use:

PD004 and 5 are 400 (frequency)
PD009 = 15 (intermediate voltage)
PD011 = 120
PD014 = 2.5 (acceleration time)
PD015 = 2.5 (deceleration time)
PD025 = 1
PD072 = 400
PD141 = 220 (motor rated voltage)
PD142 = 8 (max current, amps)
PD143 = 2 (motor poles)
PD144 = 3000 (rpm display scaling - had to look that one up)

You'll probably find some, or even most of them are already set. PD003 is just the frequency it starts with on the display, so before you press run I'd set it to something low (say 50Hz) to check everything is ok then work up to 400Hz. Needn't worry about setting up the water cooling to start with as it'll easily survive the couple of minutes it takes to test without cooling.

For wiring ... 4-core shielded from VFD to motor, connect earth at machine (spindle mount is probably easiest) and frame and the other end to the earth connection in the VFD. 3 power wires from motor go to UVW in no particular order. If they're the 'wrong' way the spindle will start spinning the wrong way, so to avoid pressing reverse every time just swap any two of UVW wires (like you could on a stepper motor phase). Mains input to RST, pick any 2 any way round as it makes absolutely no difference (since it's just got a 3-phase rectifier in there) and remember the earth, otherwise you'll get a mains shock off the machine frame which gets less amusing after the first few times!

Also make sure the wire close to the spindle connector is clipped to the Z-axis so that there's no tension on the cable. The constant bending otherwise can cause various problems as the wire degrades (took me a while to find what was causing that one), or if you're unlucky it could snap/short and destroy the VFD and spindle. Not mentioning any names

This picture shows what I mean, though actually I took it to show the air cooling:
