Status for the counter can be read in par.16-35
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
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.).
