DC BUS over-voltage at stop
Corrective Actions:
1.
Check if the input voltage falls within the rated AC
motor drive input voltage range.
2.
Check for possible voltage transients.

Corrective Actions:
1.
Ensure that the ambient temperature falls within the
specified temperature range.
2.
Make sure that the ventilation holes are not
obstructed.
3.
Remove any foreign objects from the heatsinks and
check for possible dirty heat sink fins.
4.
Check the fan and clean it.
5.
Provide enough spacing for adequate ventilation.
