Monitoring current value

With the FREQROL-U100 series, pressing and holding the [SET] switches to the current monitor. 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 >>

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 >>

Input terminal function selection of multi-function series

You can use the input terminals X1 to X3 for an input terminal function such as 7-speed operation (high, middle, and low speed), output stop during motor ope... More Details >>

What happens if reset occurs during operation?

This is because when the inverter restarts while the motor is coasting, an overcurrent trip can occur during the restart process. However, the recent types o... More Details >>

Energy saving effect of inverter operation

Energy saving operation of the inverter is represented by comparison with commercial power supply operation. 　For example, to control air volume of an air co... More Details >>
