Servo Drive Repair

How a Servo Drive Works
GE FANUC repair services provided by CNC parts supplier

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.

For more specific information regarding the operation of servo drives, consult our guide on how servo drives work, or contact our experienced professionals at Tri Star CNC at 815-578-9145.

Common Symptoms of a Malfunctioning Servo

With enough years of operation, and wear and tear, even the highest quality servo drives will need maintenance or repairs. FANUC’s DC servo drives commonly exhibit the following errors:

  • Erratic operation and vibration
  • Failure of detection circuits
  • Blown fuses
  • Malfunctioning OVC and HC alarms

FANUC AC servo drives can fail for a wide variety of reasons. No matter the problem, Tri Star CNC has the parts and the expertise to correct it.

Spindle Drive Repair

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.

Spindle Amplifier Problems

Any hiccup due to component error compromises the effectiveness of the CNC process.

Like any equipment used in high-volume CNC applications, spindle amplifiers can develop problems which require servicing. Some common issues we see with FANUC spindle drives are erratic operation, ALM-12, no rotation, feedback failure and a wide variety of other reasons.

FANUC Drive Alarm Error Codes

Tri Star CNC Services helps you identify FANUC drive error codes and diagnose the reason for the fault. Spindle drives fail for a number of reasons: high temperatures, low voltage, abnormal current, faulty circuits, communication errors and many, many more.

Even the clearest explanation from your machine’s manual or from our own list can seem daunting to the untrained eye. Give us a call and we’ll let you know what must be done to get your CNC machinery up and running again.
