Was bedeutet oL3 ?
The drive's output current (or calculated torque in OLV, CLV, AOLV/PM, CLV/PM modes) has exceeded the threshold set in L6-02 for longer than the time specified in L6-03. This fault typically indicates either incorrect parameter settings for torque detection or a mechanical issue on the machine side causing excessive load on the motor. Ignoring this can lead to damage to the motor, gearbox, or driven equipment.
Häufige Ursachen
- Mechanical jamming or obstruction in the driven load requiring excessive torque.
- Sudden increase in load demand beyond the motor's or drive's capacity.
- Incorrect setting of parameter L6-02 (Overtorque 1 Detection Level) too low.
- Incorrect setting of parameter L6-03 (Overtorque 1 Detection Time) too short.
- Motor undersized for the peak torque requirements of the application.
Reparaturschritte & Checkliste
Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.
- 1
Inspect the mechanical system (e.g., gearbox, conveyor) for signs of jamming, binding, or unusual resistance.
- 2
Measure the drive's output current (A) during typical operation and during the overtorque event.
- 3
Review parameter L6-02 (Overtorque 1 Detection Level) and L6-03 (Overtorque 1 Detection Time); adjust based on load.
- 4
Verify motor parameters (P1-01 to P1-08) are correctly entered for accurate torque estimation.
- 5
Check for sudden load changes or shock loads during the operating cycle that might momentarily exceed the limit.
- 6
Compare the motor's rated torque (Nm) to the peak torque required by the application.
