Status for the counter can be read in par.16-35
Inverter Thermal
.
If par.14-61
Function at Inverter Overload
is set to Derate, the pump speed will be reduced when the counter exceeds 98, and stay reduced until the
counter has dropped below 90.7.
If par.14-62
Inv. Overload Derate Current
is set e.g. to 95% a steady overload will cause the pump speed to fluctuate between values corresponding to
110% and 95% of rated output current for the frequency converter.
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.).
