Overtorque 2

¿Qué significa oL4 ?

The drive's output current (or calculated torque in OLV, CLV, AOLV/PM, CLV/PM modes) has exceeded the threshold set in L6-05 for longer than the time specified in L6-06. Similar to Overtorque 1, this suggests either parameter misconfiguration or a significant mechanical overload on the driven equipment. Sustained overtorque conditions can result in mechanical stress, equipment damage, or shortened lifespan of motor and machine components.

• Persistent high mechanical load or friction in the driven equipment.
• Incorrect parameter setting for L6-05 (Overtorque 2 Detection Level) set too low.
• Incorrect parameter setting for L6-06 (Overtorque 2 Detection Time) set too short.
• Motor experiencing sustained operation beyond its continuous rated torque.
• Misalignment or wear in bearings or other mechanical components leading to increased friction.

1. 1

   Inspect the mechanical system for signs of wear, misalignment, or components requiring lubrication.

2. 2

   Monitor the drive's output current (A) and torque feedback (if available) during the process cycle.

3. 3

   Review parameter L6-05 (Overtorque 2 Detection Level) and L6-06 (Overtorque 2 Detection Time); adjust as necessary.

4. 4

   Confirm motor nameplate data (e.g., rated current, rated torque) is accurately configured in P1-01 to P1-08.

5. 5

   Perform a no-load test on the motor and driven equipment to establish a baseline current.

6. 6

   Measure actual mechanical torque at the load using a torque wrench (if feasible) to correlate with drive readings.
