It’s 2011 machine, we just got it out of auction.

It spins freely by hand, I checked the encoder (it was very dirty and oily, but it works) I clean it and installed it back to the spindle. The encoder seems like giving a right measuring to the computer when I spin the spindle by hand. I checked the eye delta contractor, it looks good, no signs of any damage. Voltage going in and out, same voltage at all pins. All three phases reaches the spindle motor. So no meter what number of rpm’s up to 1000 It spins 10 rpm. If I program it to go 2000 rpm it spins 40-60 rpm.
I’m struggling with it for a few days already, please help me with any advice or thoughts.
How are you powering the machine with a 3Ph supply or a RPC.
