Symptoms of a malfunctioning spindle drive/amplifier

CNC Spindle Repair Services

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.

FANUC spindle error alarm codes

Spindle failure can occur for a number of reasons completely foreign to someone on the floor with no experience with internal electronic CNC machine components. Even the most detailed explanation in a manual (or in our own list) can be intimidating. If you’re having trouble diagnosing or navigating your machine’s symptoms, Tri Star CNC provides over-the-phone guidance from experts to help you through it.
