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 >>

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 >>

How can I have the motor coast to stop?

You can use the following two methods:1. Turn ON MRS at the same time when STF turns OFF.2. Set Pr.10 = 60 Hz, Pr.11 = 0 sec, and Pr.12 = 0% (when the invert... More Details >>
