 Overload

    Permissible overload in the constanttorque speed regulation is over 2xTn for IP54 version and 1.6xTn for IP23version, it is however given by the maximum available voltage from the inverterdue to the voltage, maximum torque decreases near the nominal speed to a minimumvalue of 1.3xTn for tables with 3x360VRMS and 1xTn for tables with 3x400VRMS atspeed higher than nn, the overload margin decreases to zero at nmax1 curve of thepicture between nmax1 and nmax2 show power output limit due to the voltagesupplied by the inverter. However, the RMS power must not exceed the nominalvalue Pn.
