is used to set the time elapsed before the motor trips under a load of 150% (overload trip

)
within a range of 10 to 2400 seconds.

3) Inverter overload detection method
f631 f631 f631 f631
As this function is set to protect the inverter unit, this function cannot be turned off by parameter setting.
The inverter overload detection method can be selected using parameter
f631
(Inverter overload detection method).
If the inverter overload trip function (
ol1
) is activated frequently, this can be improved by adjusting the stall operation

(150%-60s)
Protection is given uniformly regardless of temperature by the 150%-60 sec overload curve.


(Temperature estimation)
This parameter adjusts automatically overload protection, predicting the inverter internal temperature rise.
4) Electronic thermal memory

When the power is OFF, it is possible to reset or maintain the overload totaling level.
This parameter's settings are applied both to the motor's electronic thermal memory and the electronic thermal memory
for inverter protection.
5) Overload alarm level

When the motor overload level reaches to
f657
setting value (%) of overload trip (

” will be displayed
on the left side digit and the “
l
” and output frequency monitor will be blinking alternately on overload alarm status.
Overload alarm signal can be output from output terminal.
