1. 1

   Inspect the drive's heatsink fins and cooling fan for dust, debris, or obstructions.

2. 2

   Verify the cooling fan's functionality and free rotation when the drive is powered on.

3. 3

   Measure the ambient temperature within the drive's enclosure and verify it is within the specified operating range.

4. 4

   Monitor the drive's output current (U1-01) on the display and compare it against the motor and drive rated currents for potential overload.

5. 5

   Verify drive parameters such as carrier frequency (C1-01) and motor full load current (E1-04) against application requirements.
