Fanuc 2S AC spindle motor on Delta C2000+

Reset the vfd, did startup wizard, only changed these parameters (bold = default):
P00-10 control method velocity mode
P00-11 velocity mode vf open ctrl
P00-16 load select heavy duty
P00-17 carrier freq 4khz
P1-00 max out freq 250hz
P1-01 motor f base 50hz
P1-02 max out volt 1 200v
P1-10 mid out freq 1-1 3hz
P1-04 mid out volt 1-1 22v
p1-05 mid out freq 1-2 1.5hz
p1-06 mid out volt 1-2 10v
P1-07 mid-put- freq 1 1.5hz
​​​p1-08 min out-volt 1 32v
P1-10 upper bound freq 250hz
p1-12 1st accel time 10s

I'm kinda thinking this vfd is just too underrrated for this setup.
Considering the output voltage is max 200V and my vfd is limited to ~11A , it could handle the ~2.2kw max of the motor. but probably has too little juice for low rpm's.

As when it is trying to ramp up the current on the display is like 17.5A which my vfd can do in short burst but not long.

That would leave the following options:
- Fit it with a 7.5 -10kw vfd
- Re-fit the OEM 380 - 200V trafo and get a 3X230v ~4kw vfd
- Replace the motor with a china 380V equivalent

I'm thinking about the last option as that makes life easier. The cost of all of these options are pretty much the same.

Yes, usually for lower voltage you need a more powerful driver.  But it should still work but you won't be able to use it at full power.  Did you follow these settings?

Let me go run auto-tune. And see if it changes much.

I first did static im autotune and that worked.
So i did the rotary im and it faulted as oL3 derating error:

So i changed the carrier freq from 8 to the lowest setting 2. The autotuning took a bit longer but errored out on the same.

Try a slower acceleration
