• Gain = 0%, Bias = 100%, A1 as frequency reference inputThis setting leads to an inverse-acting frequency reference. The minimum analog input level (0 Vdc) will produce a 100%frequency reference and the maximum analog input level (10 Vdc) will produce a 0% frequency reference.0 V 10 VGain = 0 %Bias = 100 %FrequencyreferenceFigure 5.31 Frequency Reference Setting by Analog Input with Inverse Gain and Bias Settingsn H3-13: Analog Input Filter Time ConstantParameter H3-13 sets the time constant for a first order filter that will be applied to analog input A1 and also to the referencevalue from potentiometer option (AI-V3/J).No. Name Setting Range DefaultH3-13 Analog Input Filter Time Constant 0.00 to 2.00 s 0.03 sAn analog input filter can be used to prevent erratic drive control when a “noisy” analog reference is used. The drive operationbecomes more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals.u H4: Multi-Function Analog Output Terminal AMThese parameters assign a function to analog output terminal AM for monitoring a specific aspect of drive performance.n H4-01: Multi-Function Analog Terminal AM Monitor SelectionSets the desired drive monitor parameter Uo-oo to output as an analog value via terminal AM. Refer to U: Monitors onpage 201 for a list of all monitors. The “Analog Output Level” columns indicates if a monitor can be applied for analog output.Example: Enter “103” for U1-03.No. Name Setting Range DefaultH4-01 Multi-Function Analog Terminal AM Monitor Selection 000 to 999 102A setting of 031 or 000 applies no drive monitor to the analog output. With this setting the terminal AM output level can beset by a PLC via a MEMOBUS/Modbus communications interface (through mode).n H4-02/H4-03: Multi-Function Analog Output Terminal AM Gain/BiasParameter H4-02 sets the output voltage that is equal to 100% of the monitor value. Parameter H4-03 sets the output voltageequal to 0% of the monitor value.Both values are set as a percentage of 10 V. The minimum output voltage for terminal AM is 0 V, the maximum is 10 Vdc.Figure 5.32 illustrates the function of the gain and bias settings.No. Name Setting Range DefaultH4-02 Multi-Function Analog Output Terminal AM Gain -999.9 to 999.9% 100.0%H4-03 Multi-Function Analog Output Terminal AM Bias -999.9 to 999.9% 0.0%5.6 H: Terminal Functions110 YASKAWA ELECTRIC SIEP C710606 31B YASKAWA AC Drive – J1000 Technical Manualhttp://nicontrols.com
