  • Connecting ammeter to output side

    Yes. Use a moving-iron type ammeter. However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the inter... More Details >>

  • Terminal FM

    No. This is because the current cannot flow if the total internal impedance of the meter connected to the terminal FM is 300 Ω or higher.You can connect mult... More Details >>

    • No：21864
    • Release Date：2018/08/22 16:29

  • Frequency setting

    To accept the current signal, the terminals AU (current input selection) and SD must be short-circuited. Check it.Note that this terminal AU is not prepared ... More Details >>

    • No：21799
    • Release Date：2018/08/22 16:29

  • Frequency setting signal

    Calibrate C6 (Pr.904) (Terminal 4 frequency setting bias frequency) and C7 (Pr.905) (Terminal 4 frequency setting gain frequency). If the situation does not ... More Details >>

    • No：21265
    • Release Date：2018/08/22 16:26

  • Frequency setting

    Since Pr.3 (Base frequency) is a parameter to set the rated motor frequency, setting it to 80 Hz does not increase the frequency.Set this parameter to the ra... More Details >>

  • Terminal

    Signals input from the terminal 4 are not enabled if the terminal AU is not ON. For an inverter without the terminal AU, assign the AU function to an unused ... More Details >>

  • Replacement

    It is Pr.125 (Terminal 2 frequency setting gain frequency). Adjust the slope with C4 (903) (Terminal 2 frequency setting gain) as necessary. More Details >>

  • Frequency

    It seems that calibration for 20 mA current signal input is not correct.Use the calibration parameters "126" and "C7" to calibrate the inverter.Perform calib... More Details >>

  • Current setting

    Yes.The parameters used when the terminal 4 is used are C5, C6, 126, and C7.Set Pr.C5 (Terminal 4 frequency setting bias frequency) while feeding a current s... More Details >>
