Symptoms of a malfunctioning spindle drive/amplifier

When maintained, the control, drive and motor of a spindle should work together with precision and accuracy. When they fail, FANUC’s spindle drives frequently exhibit these error, among others:

Spindle Amplifier Operation

A spindle drive controls the high-speed, compact AC motors commonly used in machine tool spindle drive applications. Since maintaining consistent speed and torque is essential to accuracy and finish quality, these devices use digital signal processors to constantly monitor and adjust speed, torque and current to minimize variations in speed and torque during use.
