Fanuc 2S AC spindle motor on Delta C2000+

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

I'm really sorry for my earlier knee-jerk post.  The newer versions of the Fanuc spindle motor are PMs, so it's possible that yours is also a PM.

 

I did the "short a pair of wire" test but there is no detent at all so must be an induction motor.
Also changing the accell to 60 seconds for example does not change the behavoir.

I have a quick chat with a delta guy tomorrow, perhaps he has some insight.

drive  have 3 control loop
the first is current loop can auto tuning with motor parameter
second is speed loop and third is position loop if need
delta C2000 look like have speed loop auto tuning, but maybe need mod by manual


 

I think there is a mistake here.  Rated Frequency should be for 1500rpm 

 

ps. Parameter 01-00 specifies the maximum motor frequency

motor rate fequency is 50hz
