Proper use of AC reactor and DC reactor

1. ACL has the input power factor of approximately 90% and DCL has the input power factor of approximately 95%. Therefore, DCL has a higher input power facto... More Details >>

Brake unit selection

1. The BU brake unit does not have the fault output.Multiple BU brake units can be connected in parallel.2. Power supply voltage 480 V- What resistance value... 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 >>

Do you have an explosion-proof type?

We offer the FR-A200E-based pressure-resistant explosion-proof motor driving inverter FR-B series. This series have been certified in the explosion-proof tes... More Details >>

What is the replacement of the FR-BOL?

We do not offer a replacement product for the FR-BOL (noise reduction reactor). Since the FR-A100E is a low-noise type inverter, the motor noise is suppresse... More Details >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Speed fluctuation

I use the dedicated motor SF-VR with the same capacity as the inverter. 1. Load fluctuationSpeed fluctuation ratio with the load fluctuation 0 to 100% is:Wit... More Details >>

Using dedicated motor

Since the inverter power supply uses the single-phase input, you cannot use a 0.75K inverter with a 0.6 kW motor to draw the maximum ability of the motor. To... More Details >>

Noise filter

We offer DC reactors from 0.4K and you can use it. 　You can use FR-BIF, FR-BSF, and FR-BEL together. More Details >>

Motor characteristics at low input voltage

Since the dedicated motor is designed with the rated voltage of approximately 320 V, it can produce sufficient torque for the input voltage of 380 V. Therefo... More Details >>
