Common Yaskawa Servo Drive Problems We Repair

Yaskawa servo drives are generally reliable, but like all electronic equipment, they can experience failures over time. Our technicians are highly skilled in diagnosing and repairing a wide array of common issues. Here are some of the common problems we address:

  • No Output: The servo drive fails to provide any output voltage or current to the motor.

  • Overvoltage Errors: The drive detects an overvoltage condition, potentially damaging internal components.

  • Overcurrent Errors: The drive detects an overcurrent condition, often indicating a motor or wiring issue.

  • Communication Errors: The drive loses communication with the controller or other devices.

  • Overheating: The drive overheats due to excessive load, inadequate cooling, or component failure.

  • Blown Fuses: Internal fuses blow, indicating a short circuit or other electrical fault.

  • Encoder Faults: The encoder, which provides feedback on motor position, malfunctions.

  • Positioning Errors: Inaccurate or inconsistent positioning of the motor.

  • Drive Not Enabling: The drive fails to enable, preventing motor operation.

  • Power Supply Issues: Problems with the internal power supply, leading to unstable operation.

  • Software or Firmware Corruption: Issues with the drive's internal software or firmware.
