Suggestion for replacement of inverters

We do not offer book type inverters. Therefore, the S500 is recommended to replace the Z123 because of its compact design. If regenerative driving matters, c... More Details >>

Power supply phase loss

The following is the case for the FREQROL-A500 series:1. When the R phase or S phase is lost, the inverter stops since it loses the control power supply.2. W... More Details >>

Frequency setting

You can use it for inverter operation, but the running speed of the inverter does not change linearly with regard to turn of the frequency setting potentiome... More Details >>

Electromagnetic contactor

Turning ON/OFF the output side during operation causes open/close surges that may trigger the protective function (against overcurrent or overvoltage) of the... More Details >>

FR-Configurator

If the values are already entered in the setting column, performing batch write reflects the setting on the inverter. More Details >>

Connecting ammeter to output side

Yes. Use a moving-iron type ammeter. However, if the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the inter... More Details >>

Automatic overload control of inverter

The inverter has the current limit function. This automatically controls the frequency so that the preset current value may not be exceeded. (Note that the m... More Details >>

Terminal indicator lamp

The inverter outputs the peak voltage 300 to 400 VDC of the bus voltage not in a pure sine wave but a in a PWM waveform. Check if the lamp to be connected ca... More Details >>

Rated frequency setting

Check that Pr.3 (Base frequency) is set to "200 Hz". Adjust Pr.0 (Torque boost) as necessary. More Details >>

Country of origin

The country in which the product is manufactured is described on the rating plate as MADE IN JAPAN or MADE IN CHINA. More Details >>
