Overtorque Detection 2
Yaskawa · V1000 AC Drive
What does oL4 mean?
This fault triggers when the drive's output current surpasses the level set in L6-05 for longer than the time specified in L6-06. Similar to oL3, it points to a machine issue, such as a locked rotor or improperly set load parameters. Persistent overtorque can lead to mechanical strain, premature equipment wear, or even motor damage.
Complete Troubleshooting Guide
- 1
Perform a detailed inspection of the machine for any physical impediments or seizing components, then address and clear the root cause.
- 2
Carefully review and modify the L6-05 [Torque Detection Level 2] and L6-06 [Torque Detection Time 2] parameters to accurately reflect the machine's operational load requirements.
- 3
Execute a Fault Reset to clear the fault from the drive's memory after troubleshooting.
