OL3

Overtorque Detection 1

Yaskawa · VS-616G5 Variable Speed Drive

What does OL3 mean?

The OL3 alarm indicates that the motor's current or torque has exceeded the programmed Overtorque Detection 1 Level (L6-02) for a duration longer than the Overtorque Detection 1 Time (L6-03). This suggests an excessive mechanical load or an obstruction in the driven equipment.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Review parameters L6-02 (Overtorque Detection 1 Level) and L6-03 (Overtorque Detection 1 Time); adjust them if they are set too sensitively for the application, ensuring adequate protection.

  2. 4

    Check the driven machinery for any signs of wear, misalignment, or component failure contributing to increased torque.
