| F004 | Ground fault |
Case Studies: Real-World Examples of Fault Code Troubleshooting
Case Study 1: Overcurrent Fault (F003)
Benefit: Rapid identification of excessive current draw, preventing component damage and potential safety hazards.
How to do:
- Check load torque to ensure it does not exceed the drive's rated capacity.
- Inspect cables for damage or loose connections that may cause current leakage.
- Refer to the drive's fault history log for additional fault code details.
| Fault Code | Description |
|---|---|
| F003 | Overcurrent |
| F007 | Overheat |
| F012 | Ground fault |
| F013 | Motor overload |
Case Study 2: Undervoltage Fault (F002)
Benefit: Detecting low voltage conditions that can impair drive performance or damage connected equipment.
How to do:
- Verify if the input voltage supplied to the drive is within the specified range.
- Check for voltage drops across the drive's power terminals.
- Ensure proper grounding of the drive and any connected devices.
| Fault Code | Description |
|---|---|
| F002 | Undervoltage |
| F004 | Overvoltage |
| F005 | Overload |
| F006 | Motor fault |
