14-61 Function at Inverter Overload
Option: Function:
Is used in case of steady overload beyond the thermal limits (110% for 60 sec.).
[0] * Trip Choose Trip [0] to make the frequency converter trip and provide an alarm.
[1] Derate Derate [1] to reduce pump speed in order to decrease the load on the power section and allowing
this to cool down.
14-62 Inv. Overload Derate Current
Range: Function:
95 %* [50 - 100 %] Defines the desired current level (in % of rated output current for the frequency converter) when
running with reduced pump speed after load on the frequency converter has exceeded the allowable
limit (110% for 60 sec.).
