GB - 57Parameter descriptionLA.03 AN1 zero point hysteresisValue range Setting Description0…±10 % 0,2 % Through capacitive as well as inductive coupling on the inputs lines or voltagefluctuations of the signal source, the motor connected to the inverter can drift(„vibrate“). during standstill in spite of the analog input filter. It is the job of thezero point hysteresis to suppress this.The parameter masks out the analog signal in the adjusted value range. Thevalue applies to both directions of rotation.If a negative percentage is adjusted, the hysteresis acts in addition to the zeropoint also around the current setpoint value. Setpoint changes are acceptedonly if they are larger than the adjusted hysteresis.Fig. LA.03:Zero Point Hysteresis-10%10%10%-10%mask-outrangeof interference filgterfor further signal processingLA.04 AN1 amplificationValue range Setting Description0,00…±20,00 1,00 The amplification of the input signal is adjusted with this parameter. At anamplification of 1.00 the input value corresponds to the output value.Fig. LA.04:Amplification of´theanalog input signal 100%100%-100%-100%input value (In)output value (Out)Formula for the calculation ofthe output value Out = amplification • ( In - Offset X) + Offset YLA.05 AN1 Offset XValue range Setting Description0,0…±100,0 % 0,0 % The parameter shifts the input characteristic on the X-axis.
