Symptoms of a malfunctioning servo drive/amplifier
Since drives and amplifiers are so important in FANUC machinery, it is easy to notice when they are malfunctioning. If maintained, an axis’s control, motor and drive work together with precision and accuracy. When they fail to perform, axes frequently exhibit these errors, among others:
- Erratic rotation and vibration
- Failure of detection circuits
- Blown fuses
- Occurrence of OVC and HC alarms
If you notice these issues, call Tri Star CNC for FREE phone support troubleshooting.
FANUC servo error alarm codes
Servo failure can occur for a number of reasons, making the list of possible problems overwhelming to the untrained eye. 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.

How a Servo Drive Works
A servo drive takes the command signal sent from a control panel and amplifies the low power signal up to a level which results in movement of the servo motor. As the servo motor is activated, a sensor reports the status of the motor to the servo drive via a feedback signal. The control compares what the motor is doing with the command it received and alters the voltage frequency going to the motor in order to correct any deviation from the original command.
