Input phase loss

Check if the input side voltage is equally applied to all three phases. The S phase voltage may be low because the input current flows when the voltage of th... More Details >>

RUN blinks

When using the setting dial to set the frequency, turn the dial and press the "SET" key while the desired value flickers. (The value and "F" flicker alternat... 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 >>

Running frequency

There are two methods to reduce the running frequency variation. 1. Increase the setting value of Pr.74 (Input filter time constant) to reduce the variation.... 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 >>

Frequency setting

As the AS-OX has the "0ADJ" potentiometer for frequency meter calibration, use it to adjust the meter so that both readings match.　　 More Details >>

MRS setting

1. For MRS, coasting starts when the MRS contact turns ON. For Pr.250 = "0",IM is coasting immediately when the start signal is turned OFF. 　2. No. Set eithe... 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 >>
