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 >>

Using both types of power factor improving reactors

Yes.By using both types of reactors together, you can reduce the outgoing harmonic current.For examples of harmonics reduction, refer to the value in the har... More Details >>

Control method

1. Can I set the frequency by the external potentiometer when multi-speed signal is 0 (nothing is input)?-> It is possible by using the external operation... More Details >>

Regenerative brake resistor

The brake resistor is not built in the inverter. Purchase the optional resistor and connect it to the inverter.Inverter only (without resistor)Continuous reg... More Details >>

Rated capacity related to harmonic suppression guidelines

The usual inverter input current is determined not by the inverter capacity but by the motor capacity (motor load).Therefore, the input side capacity is not ... More Details >>

Surge voltage of 400 V inverter

1. Since the voltage resistance of the standard motor is not improved, it is recommended to use an "insulation-enhanced motor".If you are using an insulation... More Details >>

Terminal assignment

The terminal MRS assignment parameter is Pr.183. Set Pr.183 to "4" (AU). (This setting is for the E700.) More Details >>

Auto tuning

Check if any device is connected to the inverter's external terminal.In particular, check if MRS and SD are short-circuited.If they are short-circuited, open... More Details >>
