Parameter unit display

Setting Pr.37 to the machine speed at 60 Hz switches the frequency monitor to the rotations per minute monitor.Note that the speed setting must be input in a... More Details >>

Operation command terminal switching

It rotates in the forward direction while STF is ON.And then, when STR is turned ON and STF is turned OFF, the inverter decelerates down to 0 Hz within the s... More Details >>

Common terminals of control circuit

If you ground the common terminals of the control circuit, it is connected with the inverter's earthing and the inverter's noise may be input to the control ... More Details >>

Fault contact when connecting separate power supply for each control circuit

Since the inverter's fault contact is an NC contact, it does not open unless a fault occurs.Therefore, when the control power supply (and main circuit power ... More Details >>

Speed control range

Many geared motors cannot continuously operate at low speed (for example, slower than 6 Hz) due to grease viscosity.If the motor you are using is of this typ... More Details >>

Installation of FR-BLF

The following benefits are provided when the FR-BLF is installed on the input side or output side.Choose the side to install the FR-BLF considering these ben... 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 >>

Using built-in potentiometer and multi-speed together

Yes. Set Pr.79 = 3. (Input the start signal from an external source.) More Details >>
