We have an Hatichi 25S turning center, with a Fanuc AC Spindle Drive A06B-6044-H039. The drive was repaired by Fanuc and is working, but the S-code spindle speed commanded does not match the displayed spindle RPM on the screen. When a speed of S3000 is commanded, we see an RPM of approx 3300, a difference of about 300. Spindle speed override set at 100%
How can we make the speed match the S-code?
Cheers,
Steve
