Automatic restart after instantaneous power failure setting

You also need to set Pr.57 (Restart coasting time).The function does not work just by setting Pr.162 unless setting this parameter.(For A700, F700, and F700P... More Details >>

Input phase loss

Check if the input side voltage is equally applied to all three phases. The S phase voltage may be low because the input current flows when the voltage of th... More Details >>

Megger test

When carrying out the megger test of the inverter, shorten all the terminals R, S, T, U, V, and W of the main circuit and use the 500 VDC megger for earth. D... More Details >>

The following causes are probable for this Err display:- Operation error (for example, you tried to input a value other than the available range of parameter... More Details >>

Output voltage

Since the output frequency was measured, it is considered that the start signal was input correctly.Check the output voltage on the voltage monitor of the in... More Details >>

The lifetime of EEPROM write

It is said that the EEPROM has a lifetime of 100,000 write cycles. When the data is written every time the frequency changes, the life of the EEPROM may not ... More Details >>

Output frequency

When Pr.80 and Pr.81 are set to the value other than "9999", control other than V/F control is performed. For the FR-F700(P) FR-D700, and FR-F700PJ, Pr.81 is... More Details >>

Operation panel

Since the operation panels of the E700, D700, and F700PJ do not have keys for the forward (FWD) and reverse (REV) rotations, you can only command rotation in... More Details >>
