Carrier frequency of low-noise series

The carrier frequency is initially set to 7 kHz. (When Pr.10 is set to "---", you can set or change the setting using Pr.72.) Raising the carrier frequency r... More Details >>

Difference between multi-function and standard products

The following are added to the multi-function product in addition to the standard product: - Input terminal function selection (X1 to X3)- Warning NO contact... More Details >>

DIN rail installation

You can do it by using the optional DIN rail attachment (FR-DU01/02). More Details >>

Noise and leakage current (tone modulation control) of low-noise series

When the carrier frequency increases, noise and leakage current increase accordingly. To prevent the noise and leakage current from increasing while keeping ... More Details >>

Speed setting

The high speed command (multi-speed command) is prioritized over the frequency setting potentiometer. It is OK if these are both input simultaneously. When t... More Details >>

Can I connect a brake resistor?

You cannot connect a brake resistor to the FR-U100 series inverter. (Use the FR-A024 series if you use the brake frequently.) More Details >>
