Mechanical Weakening Detection 2

Yaskawa · GA500 Maintenance and Troubleshooting

Hva betyr UL5 ?

This error is generated when the drive detects an undertorque condition that satisfies the criteria for mechanical weakening, as configured by the L6-08 [Mechanical Fatigue Detect Select] parameter. This suggests potential wear, damage, or loosening of mechanical components within the system. Unresolved mechanical weakening can lead to catastrophic equipment failure.

Vanlige årsaker

  • Calculated motor current indicates excessive mechanical stress (P4-09).
  • Sudden surge in mechanical resistance.
  • Component failure in the driven machinery.
  • Drive detecting abnormal mechanical strain.

  1. 1

    Conduct a detailed examination of the machine to identify any signs of mechanical deterioration, such as loose parts or wear.

  2. 2

    Replace or repair any components found to be deteriorating or damaged.

  3. 3

    Perform a Fault Reset to clear the error after necessary repairs are completed.
