(3) Thermal warning
You can configure this function so that the inverter outputs a warning signal before the electronic thermal
protection operates against motor overheat. You can also set the threshold level to output a warning signal
with the electronic thermal warning level setting (C061).
To output the warning signal, assign function "13" (THM) to one of the intelligent output terminals [11] to
[15] (C021 to C025) and the alarm relay terminal (C026).

Setting of the threshold level to output the
thermal warning signal
*1 Set the ratio (%) of the warning level to the integrated value of the electronic thermal characteristic. A
setting of 100% corresponds to the inverter trip due to overload (error code "E05").
