 = (Variable torque characteristic), = (Temperature estimation)
This parameter adjusts automatically overload protection, predicting the inverter internal temperature rise.
(diagonally shaded area in the figure below)
time [s]
Note 1: The rated output current of inverter is changed by setting of aul=1 or 2.
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.
6) Overload alarm level f657
When the motor overload level reaches to f657 setting value (%) of overload trip (ol2) level, "l" 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.
