6.3.12 Inverter protection
Inverter overload reaction
Selects reaction of inverter to an internal over-temperature.
0 Reduce output frequency
1 Trip (F0004)
2 Reduce pulse frequency and output frequency
3 Reduce pulse frequency then trip (F0004)

Inverter temperature warning
Defines the temperature difference (in ºC) between the overtemperature trip threshold and
the warning threshold of the inverter. The trip threshold is stored internally by the inverter
and cannot be changed by the user.

Delay, fan shutdown
This defines the delay time in seconds between powering down the frequency inverter and
then powering-down the fan. A setting of 0 means that the fan is immediately shut down
(powered-down).
