Generally speaking, if the load characteristic is not known as a definite value, thelinear characteristic should be set. In the case of linear characteristic curves, the motorachieves full torque throughout the entire speed range. For this, a thermal overload of themotor must be prevented through suitable measures (complete motor protection throughusing thermocontact or PTC thermistor-monitoring).Motor Setup EdgefrequencyThe maximum output voltage is attained during break edge frequency.Adjustment range: 10.0 - 150.0 HzFactory setting: 48.5 HzIn the case of special settings with “Edge frequency” > “Maximum frequency”, due tohigher power losses it is possible that automatic power reduction, “derating”, occurs.48.5 HzEdgefrequencyMotor Setup Max.
