Terminal

Change Pr.126 (Terminal 4 frequency setting gain frequency). 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 >>

Frequency setting

Set Pr.13 (Starting frequency) or Pr.2 (Lower limit) to "5 Hz".Also set Pr.10 (DC injection brake operation frequency) to "5 Hz".The inverter does not operat... More Details >>

Frequency setting

You can set the running frequency up to 400 Hz.It depends on the specifications of the motor used whether or not operation with a frequency of 120 Hz or high... 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 >>

Frequency setting

When the frequency is set using the setting dial, it is not necessary to set it again.The inverter memorizes the setting value internally even after the powe... More Details >>

Frequency setting

When turning the setting dial to set the frequency, press the "SET" key while the desired value blinks. (The setting frequency and "F" flicker alternately.) 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 >>

Using external potentiometer and multi-speed operation together

You can use an external potentiometer and multi-speed operation together.When an external potentiometer signal input and multi-speed setting occur simultaneo... 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 >>
