Built-in potentiometer and current input switching control

For setting the frequency, you cannot switch between the operation panel potentiometer and current input from an external source.To switch between the extern... 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 >>

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 >>

Installation method

If multiple line noise filters are wound without clearance between them, the noise reduction effect corresponding to the number of filters cannot be obtained... More Details >>

Operation at external operation/stop

It is recommended to turn OFF the start signals (STF and STR) when stopping the inverter.In this case, it is not probable that the motor rotates due to a cal... More Details >>
