ＮＩＳＳＥＩ ＣＯＲＰＯＲＡＴＩＯＮ E6581815F-1166.4.2 Setting frequency command characteristics : Analog/logic input selection (VI terminal) : Setting of VI input point 1 : Frequency of VI input point 1 : Setting of VI input point 2 : Frequency of VI input point 2 : Analog input filter FunctionOutput frequency is adjusted in relation to frequency command according to external analog signals.Analog signal is set to 0: 0 to 10Vdc, 1: 4 to 20mAdc, 3: 0 to 5Vdc. analog input filter is effective for eliminating noise from frequency setting circuit. Increase ifoperation cannot be done because noise effects stability., To fine adjust the frequency command characteristics for VI input, use the parameters f470 and f471.(Refer to section 6.4.4)[Parameter setting]Title Function Adjustment range Default settingAnalog/logic inputselection(VI terminal)0: Voltage signal input (0 - 10V)1: Current signal input (4 - 20mA)2: Logic input3: Voltage signal input (0 - 5V)0 Setting of VI inputpoint 1 0 - 100(%) 0 Frequency of VI inputpoint 1 0.0 - 400.0 (Hz) Note 2 0.0 Setting of VI inputpoint 2 0 - 100(%) 100 Frequency of VI inputpoint 2 0.0 - 400.0 (Hz) Note 2 0.1 to 0.4kW model : 60.00.75 to 2.2kW model : 90.0 Analog input filter 4 - 1000 (ms) 64Note 1: Do not set point 1 and 2 ( and ) to the same value. If they are set to the same value, is displayed.Note 2: The permission maximum rotary speed of our IPM gear motor is to 2500 rpm.Set the frequency 2500 rpm or less.(Inverter maximum frequency: 0.1k to 0.4kW model: 83.4Hz or less, 0.75 to 2.2kW model: 125Hz or less) |
