OL2 fault in an INVT GD10 drive indicates Inverter Overload. This means the inverter's output current has exceeded its rated capacity for a specific duration.
Common Causes of OL2 Faults:
-
Mechanical Overload:
- Excessive Load: The motor may be subjected to a load that exceeds its rated capacity.
- Mechanical Issues: Mechanical problems like bearing failures, belt slippage, or pump blockages can increase the motor's load.
-
Electrical Overload:
- Voltage Fluctuations: Variations in the supply voltage can lead to increased motor current draw.
- Short Circuits: Internal or external short circuits can cause excessive current flow.
- Incorrect Motor Sizing: The motor may be undersized for the application.
-
Inverter Settings:
- Incorrect Current Limit: The inverter's current limit may be set too low.
- Motor Parameter Mismatch: Incorrect motor parameters can lead to inaccurate current calculations.
-
Inverter Malfunction:
- Internal components like IGBT modules or power supply circuits may be faulty.
Troubleshooting Steps:
-
Check the Mechanical Load:
- Inspect the driven equipment for any signs of mechanical issues.
- Ensure the load is within the motor's rated capacity.
-
Verify Electrical Connections:
- Check for loose or damaged connections in the motor and inverter wiring.
- Inspect the motor windings for signs of damage or overheating.
-
Inspect the Inverter:
- Verify the inverter's current limit setting and adjust it if necessary.
- Ensure the motor parameters are correctly configured in the inverter.
- Check for any visible signs of damage or overheating on the inverter's components.
-
Monitor Motor Temperature:
- Use a thermal imaging camera or a contact thermometer to measure the motor's temperature.
- Excessive temperature can indicate an overload condition.e issue, it is recommended to consult with a qualified technician or contact INVT's technical support for further assistance.
