Inverter selection when multiple inverters are to be connected

Be sure to use a high power factor converter with the capacity higher than the total capacity of the inverters connected. (Note: One or more of the inverters... More Details >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>

Speed fluctuation

I use the dedicated motor SF-VR with the same capacity as the inverter. 1. Load fluctuationSpeed fluctuation ratio with the load fluctuation 0 to 100% is:Wit... More Details >>

Operation frequency

I cannot answer clearly because the load is unknown. The operation cycle of operating for 10 seconds and stopping for 10 seconds is OK, but it is questionabl... More Details >>

Can I use a motor of which capacity is larger than the inverter capacity?

Even when the actual load (torque) is half of the motor capacity, the current output from the inverter to the motor is not reduced to the half. Therefore, it... More Details >>

Built-in reactor

The reactor built in the FREQROL-A201 series is intended to stabilize operation of the converter circuit and differs from the FR-BAL. Note that when performi... More Details >>

Fault display

"E.OV3" is displayed when the voltage between the inverter terminals PN rises abnormally high while the inverter is decelerating or stopped. In this case, th... More Details >>

Remote setting function

Because the multi-speed terminal is disabled, it does not operate in multi-speed. More Details >>

Selection

It is not completely recommended to use F700P because the starting torque at low speed of the hydraulic pump may be larger than that of the normal pump. Sele... More Details >>
