Function
When connecting input reactor or voltage regulator or the impedance of power supply is too big, the
following phenomenon are happened.
•Overvoltage trip (, , )
•Input phase failure ()
•Unusual noise of inverter
If these phenomena are occurred, the following parameters～ should be adjusted.
When the using machine has specific resonance, the following phenomena are happened.
·Vibration of machine.
·Unusual noise of machine or Peripheral
If these phenomena are occurred, the following parameters, should be adjusted.

At first, please set  as 442 and over. Next, set  and  as bigger value when no effect by
setting  as 1000 and over.
At first, please set F484 as 0.5. Next, F484 as another value when no effect by setting F484 as 0.5.
Please set f481 as following value.
Power supply frequency is 50Hz: 531
Power supply frequency is 60Hz: 442
Note
f481～f483 are invalid, when f484 has a value excluding 0.0.
