The speed on the drive is MOTOR speed not spindle speed. Unless you have a 1:1 ratio between the motor and spindle they won't match.
We have an Mori Seiki MV40 Milling center Fanuc 15MF, with a Fanuc AC Spindle Drive A06B-6059-H212. The S-code spindle speed commanded does not match the displayed spindle RPM on the drive. When a speed of S1000 is commanded, we see an RPM of approx 717, a difference of about 283. Spindle speed override set at 100%
How can we make the speed match the S-code?
Cheers,
Hanzz

Thank for reply.
My machine use Spindle type: Built-in Mottor. I removed the cover and found the gearbox. But there is no gearbox. Since the document related to the machine has been lost, the parameter has also been lost. I don't know how many rpm maximum spindle can rotate
Can you post your paramewter file? Check parameter 5621
