Noise filter

The noise filter is not built-in the FR-E700 series. It is built in the FR-A700/F700 series with the 55K or lower capacity. More Details >>

FR-E710W

Yes. The model is FR-E710W. The input is single-phase 100 V, but the output is three-phase 200 V. More Details >>

Output specification between FM and SD

The output signal across FM and SD is pulse output. The output frequency and number of pulses of the output signal across FM and SD are proportional. However... More Details >>

Detection of the motor load

An inverter is used to rotate a motor but it cannot be used to detect whether the belt is broken or not. However, the magnitude of the load will change when ... More Details >>

Inverter circuit breaker selection

Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>

Durability in multi-speed setting

1. You can set the minimum time by setting the acceleration/deceleration time and acceleration/deceleration reference frequency. 2. No problem with the termi... More Details >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

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 >>

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 >>
