Cause : Option module fault comes when an issue in expansion modules, such as communication interfaces, encoder feedback modules, I/O extensions, and other accessories that enhance functionality.

"option module fault" in delta drive indicates an issue with one of the additional option modules installed in the drive. This means there is an issue in option module.

Troubleshooting Steps for Option Module Fault in Delta Drives:

1. Check Fault Code:

   • Review the fault code on the drive’s display or control panel to confirm that the issue is related to the option module. Consult the Delta drive’s manual to identify the specific cause of the fault.

2. Inspect Physical Connections:

   • Check the wiring and connectors between the option module and the drive. Ensure that all connections are secure, and there are no loose or damaged wires.
   • Ensure that the module is properly seated in its slot if it is installed internally in the drive.

3. Verify Module Compatibility:

   • Confirm that the option module is compatible with your Delta drive model and firmware version. Incompatible modules may not work correctly, causing faults.

4. Power Cycle the Drive:

   • Turn off the drive, disconnect the power, and then reconnect it after a few minutes. This may reset the communication between the drive and the option module.

5. Update Firmware:

   • Check for any available firmware updates for both the drive and the option module. If a firmware update is available, follow the manufacturer’s instructions to install it.
   • Updating firmware can resolve compatibility issues and improve communication between the drive and module.

6. Test the Option Module in Another Drive:

   • If possible, test the option module in another compatible drive to see if the fault follows the module. If the module works fine in another drive, the issue might be with the original drive or its configuration.

7. Swap Option Modules (if applicable):

   • If you have multiple option modules, swap them to see if the fault persists with a different module. This will help you determine if the issue is with the module or the drive.
