■ = (150%-60s), = (Constant torque characteristic)
Protection is given uniformly regardless of ambient temperature, as shown by the 150%-60 sec overload curve
in the figure below.
Inverter overload protection characteristics
■ = (Temperature estimation), = (Constant torque characteristic)
This parameter adjusts automatically overload protection, predicting the inverter internal temperature rise.
