Cause : Internal SW error comes when a malfunction within the drive's internal software. This software is crucial for controlling the drive's operation, motor interaction, and various internal functions.

Causes of Internal SW Error:

• Software Bug: A bug or error within the software code itself could be causing the issue. Bugs can be introduced during development or arise due to unforeseen circumstances.
• Data Corruption: The data used by the software for calculations and control might be corrupted due to factors like power fluctuations or hardware malfunctions.
• Hardware Malfunction (Less Likely): In rare cases, a hardware malfunction within the drive's memory or processing unit could corrupt the software or prevent it from running correctly.
