■ =( Variable torque characteristic), = (Temperature estimation)
This parameter adjusts automatically overload protection, predicting the inverter internal temperature rise.

Inverter overload protection characteristics
Note 1: The rated output current of inverter is changed by setting of
aul=1 or 2.
Refer to page L-1 about each rated output current.
Note 2: Parameter
aul is displayed as “0” during reading after this is set.
Note 3: Present setting of inverter overload characteristic can be confirmed by status monitor.
Refer to monitor “Overload and region setting” of section 8.2.1.
6) Overload alarm level f657
When the motor overload level reaches to setting value (%) of overload trip (OL2) level, output
frequency monitor and “L” of left side digit are blinking on overload alarm status.
Overload alarm signal can be output.
