1. 1

   Verify input voltage (L1, L2, L3) and frequency at the drive's input terminals against nominal specifications and check for phase imbalance.

2. 2

   Inspect all control wiring connections (e.g., digital I/O, analog I/O, communication cables) for loose terminals, damage, or improper shielding.

3. 3

   Inspect drive cooling fans for proper operation and ensure heatsinks and ventilation openings are free from dust and obstructions.

4. 4

   Review relevant drive parameters related to control modes, I/O configuration, and safety functions to ensure correct setup and integrity against a known good configuration.
