Compressor

You can use an inverter for fan and pump with the compressor, but it is not recommended for an application that the motor load rapidly increases. More Details >>

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>

Synchronous operation of two motors

When synchronously operating two motors, you need to detect speed from both motors. Each inverter is controlled based on this speed detection signal. As an e... 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 >>

Installation of new serial communication unit FR-CU03

Remove the parameter unit FR-PU03 and install there. (The installation dimensions of the FR-CU03 are the same as the FR-PU.) You can read and write parameter... More Details >>

FR-PA07

There is a priority between the setting dial and multi-speed settings.Since the multi-speed setting is given a higher priority, the setting by the setting di... More Details >>

Auto tuning

Check if any device is connected to the inverter's external terminal.In particular, check if MRS and SD are short-circuited.If they are short-circuited, open... More Details >>
