Cause : Internal microprocessor detected error comes when internal microprocessor detected error. This type of error can stem from firmware issues, hardware faults, or electrical noise.

"INFE" Internal error 14 fault in Schneider ATV950 drive indicate a problem with the "drive microprocessor", which is critical for controlling and monitoring the drive's functions.

Steps to Address an Internal error 14 (CPU) Internal Microprocessor Detected Error:

1. Immediate Actions:

   • Stop Operation: If the drive is running, stop it to prevent any potential damage or unsafe conditions.
   • Reset Error: Attempt to reset the error using the drive’s control panel. This may clear temporary issues.

2. Power Cycle the Drive:

   • Power Off: Turn off the power to the drive.
   • Wait: Wait for a few minutes to ensure all capacitors discharge fully.
   • Power On: Turn the power back on and see if the error persists.

3. Inspect Electrical Connections:

   • Check Connections: Inspect all electrical connections to the drive, ensuring that they are secure and free from damage. Loose or corroded connections can cause intermittent issues.

4. Update Firmware:

   • Firmware Version: Ensure the drive is running the latest firmware version. Firmware updates can fix bugs and improve functionality.
   • Update Process: Follow the manufacturer’s instructions to update the firmware if necessary.

5. Check for Electrical Noise:

   • Noise Sources: Identify and mitigate any potential sources of electrical noise that could be affecting the microprocessor. This includes ensuring proper grounding and shielding of the drive and its wiring.
   • EMI/RFI Filters: Ensure that any installed EMI/RFI filters are functioning correctly and consider adding them if none are present.
