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 >>

Wire length between inverter and motor

1. Wiring length between the inverter and the motor should be 500 m or less. For 0.75 kW or lower motors, the following relationship is true: Capacity... More Details >>

Frequency adjustment using potentiometer

Since the inverter is initially set to 0 Hz for 0 V and 60 Hz for 5 V, you can calculate the frequency for a certain voltage value. The equation is "Output f... More Details >>

Frequency setting increment

The value is displayed in 0.1 rpm increments under Vector control. However, the value is rounded down to the first decimal place and displayed in 1 rpm incre... More Details >>

FR-A800

Yes, the current response is also improved at the same rate. More Details >>

FR-A800

Available under vector control with an encoder.* Zero speed and servo lock are available under PM sensorless vector control only in combination with an MM-CF... More Details >>

FR-HC2

The internal transistor of the HC2 stops by turning on the SOF signal and stopping the converter. As a result, regenerative driving is not performed. However... More Details >>

FR-A800

Number of terminals: There are the same output terminals as A700 and the following terminals (2 points) are added. Safety: SO, SOC * The terminals SO and SOC... More Details >>

Power factor of inverter drive

Under 100% load, the power factors of the AC and DC reactors are 90% and 95%, respectively. For a line with no inverter control, use a power factor correctio... More Details >>

FR-A800-R2R

It is possible when the dancer control and tension sensor feedback speed control is used and the PID calculation is turned OFF. Because the PID compensation ... More Details >>
