Common Fanuc Tachometer Problems We Repair

Customers often experience a variety of issues with their Fanuc tachometers. These problems can range from simple wear and tear to more complex electrical failures. Roc Industrial LLC is equipped to diagnose and repair all types of Fanuc tachometer malfunctions.

  • No Output Signal: The tachometer fails to generate any output signal, preventing the servo drive from accurately controlling the motor's speed and position.

  • Erratic Output Signal: The tachometer produces an unstable or fluctuating output signal, leading to jerky movements and inaccurate positioning.

  • Encoder Faults: Issues with the encoder portion of the tachometer (if equipped), resulting in incorrect position feedback.

  • Communication Errors: The tachometer fails to communicate properly with the servo drive, causing system errors and shutdowns.

  • Overheating: Excessive heat buildup within the tachometer, potentially damaging internal components.

  • Worn Bearings: Deterioration of the tachometer's bearings, leading to increased friction and inaccurate readings.

  • Damaged Wiring: Broken or frayed wires within the tachometer, disrupting the signal transmission.

  • Contamination: Ingress of dirt, oil, or other contaminants into the tachometer, affecting its performance.

  • Signal Noise: Presence of unwanted electrical noise in the tachometer signal, causing inaccuracies and instability.

  • Low Voltage Output: The tachometer output voltage is lower than the specified range, impacting the servo drive's ability to control the motor.
