EF fault in an INVT GD10 drive indicates an External Fault. This fault is triggered by an external signal or condition that has been configured to cause the drive to fault.
Common Causes of EF Faults:
-
External Fault Input:
- A physical input signal, such as a limit switch or emergency stop, has been activated.
- The input signal configuration may be incorrect or faulty.
-
Communication Errors:
- Issues with the communication protocol or network can trigger an EF fault.
- Incorrectly configured communication parameters or network problems can cause the fault.
-
Hardware Malfunction:
- A hardware failure within the drive, such as a faulty input module, can lead to an EF fault.
Troubleshooting Steps:
-
Check External Fault Inputs:
- Verify the status of all external fault inputs connected to the drive.
- Ensure that the input signals are correct and that the input configuration is appropriate.
- Temporarily disable external fault inputs to isolate the issue.
-
Inspect Wiring and Connections:
- Check for loose or damaged wiring, especially at the external fault input terminals.
- Ensure proper grounding of the drive and external devices.
-
Verify Communication Settings:
- Confirm that the communication parameters (baud rate, parity, stop bits) are correctly configured on both the drive and the external device.
- Check the network cable for any physical damage or loose connections.
-
Monitor Drive's Internal Status:
- Use the drive's display or software tools to monitor internal parameters like voltage, current, and temperature.
- Look for any unusual readings that may indicate a hardware issue.
