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 >>

Changing maximum frequency

The FR-B type 30K or higher products have passed the explosion-proof test certified by the Ministry of Health, Labour and Welfare with the maximum frequency ... 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 >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Direct driven start by power supply

The warning "Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter." is indicated in the precautions at the be... More Details >>

It is considered that conditions including the power supply and noise change whether the parameter unit is connected or disconnected, influencing the analog ... More Details >>

Communication operation with FR-E500

We have no sample program for RS485 communication. Since the communication method of the FR-SW0-SETUP uses a different protocol from 485 communication and st... 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 >>

Thermal protection

Providing thermal protection is better for your safety. When the brake transistor explodes, the brake transistor alarm (E.BE) is output. Consider a counterme... More Details >>
