FR-HC2

Check that not only the current but also the various elements of the fuse such as cut-off speed and life are equivalent to those of the recommended product. More Details >>

FR Configurator SW3 (CC-Link Seamless)

It cannot be opened because FR Configurator SW3 and FR Configurator SW3 (CC-Link Seamless) are not compatible. More Details >>

Brake sequence function

It can be performed by setting Pr.292 (Automatic acceleration/deceleration) to "8" and Pr.279 (Brake opening current) to 0%. More Details >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>

Advanced magnetic flux vector control

Check the parameters necessary for tuning again.Check if Pr.9 (Electronic thermal O/L relay) and Pr.81 (Number of motor poles) are set correctly. More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Speed precision of Advanced magnetic flux vector control

The speed precision for each model is as follows:FR-K440 with PG: 1% or less of the maximum speed (3500 rpm)FR-A540 without PG (Advanced flux vector): 1% or ... More Details >>

Relationship between frequency and output torque

The output torque characteristics of the FREQROL-E500 series are shown in the figure below. Figure 1 More Details >>

FR-A800-R2R

The calculation is performed by two modes. One method calculates the current winding diameter automatically by moving the dancer roll from lower limit positi... 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 >>
