I recently had the spindle drive replaced on my Fanuc 18MA. The new spindle drive that was setup is working great. I have one question tho regarding this drive. When I try a manual spindle RPM override, the spindle speed only changes in intervals of 20% so at 80% it drops and at 60% it drops. If we reach 50%, there is no change until you try and bring the spindle back to normal speeds then it increases by 20 and reaches max speed at 90%. I have checked the drive and when the speed is set in the controller at 16,000 Rpm, the spindle drive is registering 16,480. Is that a normal thing or should I have the tech come check the drive? Any advice is appreciated. Thanks!
