• Function<br />

When connecting input reactor or voltage regulator or the impedance of power supply is too big, the<br />

following phenomenon are happened.<br />

•Overvoltage trip (, , )<br />

•Input phase failure ()<br />

•Unusual noise of inverter<br />

If these phenomena are occurred, the following parameters~ should be adjusted.<br />

When the using machine has specific resonance, the following phenomena are happened.<br />

·Vibration of machine.<br />

·Unusual noise of machine or Peripheral<br />

If these phenomena are occurred, the following parameters, should be adjusted.<br />

[Parameter setting]<br />

Title Function Adjustment range Default setting<br />

Power supply compensation filter 0-9999 (µs) 0<br />

Inhibitor filter 0-9999 (µs) 442<br />

Inhibitor gain 0.0– 300.0 (%) 100.0<br />

Power supply adjustment gain 0.0~2.0 0.0<br />

At first, please set as 442 and over. Next, set and as bigger value when no effect by<br />

setting as 1000 and over.<br />

At first, please set F484 as 0.5. Next, F484 as another value when no effect by setting F484 as 0.5.<br />

Please set f481 as following value.<br />

Power supply frequency is 50Hz: 531<br />

Power supply frequency is 60Hz: 442<br />

Note<br />

f481~f483 are invalid, when f484 has a value excluding 0.0.
