1. 1

   Turn the ATV310 drive off completely, wait for the display to extinguish, and then turn it back on.

2. 2

   Check the main power input connections to the drive for tightness and correct phase sequencing.

3. 3

   Verify the stability of the main input supply voltage, checking for sags or swells during power-up.
