Accuracy of inverter terminal FM

The pulses output from the inverter terminal FM are not completely synchronized with the inverter output frequency. The pulse circuit from the terminal FM an... More Details >>

Installing contactor on input side

It is not recommended to install a contactor on the input side and connect the auxiliary contact to the terminal STF of the inverter for the following reason... More Details >>

Inverter 200 V input and 400 V output

We do not have an inverter that directly takes 200 V input and generates 440 V output. Therefore, as you mention, use a 400 V class inverter by boosting the ... More Details >>

Motor rated rotations per minute

The inverter is capable of output up to the maximum frequency. It is the matter of whether the motor used support high-speed operation. In the situation you ... More Details >>

FR-A800/FR-F800

When connecting to the P/+, the current flows in the inrush circuit at the regenerative driving. This regenerative current may generate losses in the inrush ... More Details >>

FR-B/B3 (A800)

Yes, they are. More Details >>

FR-A800

Yes. When Pr.9 = 0, turning is performed with the inverter rated current. Always set the rated motor current. More Details >>

Cumulative pulse monitor

The count is resumed from 0. Thus, the times of the overflow is reset. More Details >>

FR-A800-CRN

Yes, it is preferred. The accuracy becomes worse when the gap between the setting value and actual value increases. More Details >>

Difference in the monitor function

The same value is displayed in the initial setting. When negative output is enabled by setting "0" to Pr.290 (Monitor negative output selection), there are f... More Details >>
