Changing Fanuc Servo Motor Alpha 6/3000i to Alpha 6/2000i

Hi Everyone,

We have a machine with Fanuc 0-M control.
We were shifting the machine. During shifting Y-Axis servo motor Alpha 6/3000i encoder was broken.(chair)
We have a spare motor but this motor is Alpha 6/2000i.
The motor is Alpha 6 with different RPM.
Can we replace the original motor (Alpha 6/3000i) with this motor (Alpha 6/2000i)
Which parameters need to be changed. I assume it is in 8100 series parameters with new motor ID.:confused:
Thanks in advance:wave:
