In the case of linear characteristic curves, the motor achieves full torque throughout theentire speed range. For this, a thermal overload of the motor must be prevented through suitablemeasures (complete motor protection through using thermocontact or PTC thermistor-monitoring).EdgefrequencyEdgefrequencyThe 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.Max. FrequencyMax. FrequencyAbove the Edgefrequency, the frequency is merely increased up to the Maximumfrequency.Setting range: 10.0 - 150 Hz (For FXDM22 maximal 60 Hz permissible!)Factory setting: 50.0 HzShutdown Freq.Shutdown Freq.Below the Shutdown Freq. the output is switched off (hysteresis approx. 1.5 % setting“Max. Frequency”) .Adjustment range: 5.0 - 150 HzFactory setting: 5.0 HzOperating Instructions Fcontrol – model series FXDM ProgrammingL-BAL-E072-GB 1642 Index 008 Part.-No.75/105
