Harmonic suppression guidelines

A 200 V class inverter of 3.7 kW or smaller is the target of the harmonic suppression guidelines for household appliances and general-purpose products, and i... More Details >>

Connecting operation panel to enclosure

To connect the operation panel to the enclosure, use the parameter unit connection cable FR-CB201, FR-CB203, or FR-CB205. The maximum cable length is 5 m. No... More Details >>

Vector control of the inverter

The speed fluctuation ratio under Advanced magnetic flux vector control of the FR-A500 is as follows. Without encoder: ±1% With encoder (with A5AP): ±0. 02 %... More Details >>

FR-HC2

Yes, the circuit board coating and conductive plating are applied to the HC2 as standard. More Details >>

Brake sequence function

Since the brake sequence function requires Advanced magnetic flux vector control and advanced flux control is applied to 0.4 kW or higher motors, you cannot ... More Details >>

Checking bit state by CC-Link communication

Because the H0F monitor only observes the ON/OFF of the hardware, it cannot be checked. More Details >>

Frequency misalignment at current input

It seems that calibration of the current input is slightly incorrect.By using Pr.904 (Frequency setting current bias) and Pr.905 (Gain), you can calibrate th... More Details >>

Consideration on power supply capacity

The inverter's power supply capacity can be calculated using the following equation:Power supply capacity [kVA] = Motor output (kW)/(Motor efficiency × Inver... More Details >>

Installation of external thermal

Since the inverter has a built-in motor overheat protective function called "electronic thermal O/L relay", the external thermal is not required. (If you use... 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 >>
