Overtorque Detection 1
Yaskawa · V1000 AC Drive
What does oL3 mean?
This fault indicates that the drive's output current exceeded the level set in L6-02 for longer than the time specified in L6-03. This suggests a mechanical issue like a machine lock-up or that the load parameters are incorrectly configured. Leaving this unresolved can lead to continued machine stress, overheating, or damage to connected equipment.
Complete Troubleshooting Guide
- 1
Inspect the machine thoroughly for any mechanical obstructions, binding, or lock-ups and remove the identified cause.
- 2
Review and adjust the L6-02 [Torque Detection Level 1] and L6-03 [Torque Detection Time 1] parameters to accurately match the operational load and prevent nuisance trips.
- 3
Perform a Fault Reset to clear the fault from the drive once the underlying issue is resolved.
