   Verify the input supply voltage (L1, L2, L3) at the drive's main terminals for stability and correct levels according to specifications.

2. 2

   Inspect the drive's control board and surrounding components for any visible signs of physical damage, corrosion, or overheating.

3. 3

   Check the integrity of all control wiring, communication cables, and grounding connections for proper shielding and secure termination, ensuring no electromagnetic interference.

4. 4

   Attempt to perform a parameter reset to factory defaults or reload a known good parameter set using the drive's keypad or diagnostic software.
