NET operation mode

Set Pr.340 (Communication startup mode selection) to "1" or "2".Also, by setting Pr.79 (Operation mode selection) to "0", "2", or "6", the inverter enters th... More Details >>

Frequency setting

This parameter cannot be changed in the external operation mode.Change Pr.77 (Parameter write selection) to "2" before changing the setting of Pr.72. More Details >>

Frequency

When the torque is supposed as 100% at 60 Hz, the torque becomes 75 % at 80 Hz. (Under V/F control, the torque decreases when the frequency exceeds 60 Hz bec... More Details >>

Frequency setting

When using the setting dial to set the frequency, turn the dial and display the frequency. Then, press the "SET" key while the desired value flickers.The fre... More Details >>

Frequency setting

The calibration parameter C6 (Terminal 4 frequency setting bias) is initially set to "20%". Therefore, voltage input to the terminal 4 does not become effect... More Details >>

10 VDC voltage from terminal 10

Setting Pr.73 to "0" does not generate 10 VDC output.The inverter itself only has 5 V at the terminal 10.Setting this parameter to "0" allows 10 V input betw... 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 >>

Brake unit

The resistors cannot be used in combination other than described. Operations of brake units and inverters are not verified. When resistors are used in uncert... More Details >>

Megger test

When carrying out the megger test of the inverter, shorten all the terminals R, S, T, U, V, and W of the main circuit and use the 500 VDC megger for earth. D... More Details >>
