Applicable motors

In addition to the dedicated motor (SF-VR series), the SF-JR series motor with an encoder can be used. You can also use a standard motor by combining it with... More Details >>

Countermeasure against noise and leakage current during low-noise operation

The following two major countermeasures against noise are available: - Keep the noise source and partner device apart from each other.- Install a noise filte... 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 >>

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 >>

PWM control

PWM is an acronym for Pulse Width Modulation and varies the switching pulse width of transistors.　This method creates many pulses within a single cycle of th... More Details >>

Parameter list

The setting memo of the parameter list seal is not provided with the FR-A500 Instruction Manual. More Details >>

Difference between use with A100 and other types

Similarly to the FR-A200 and A500, four or more filters should be used also for the FR-A100. 　In short, it is OK if the wire penetrates the filter four times... More Details >>

Outgoing harmonic current (0.1 kW, 0.2 kW)

200 V, 0.1 kW to 3.7 kW products are subject to regulation by the harmonic suppression guidelines for household appliances and general-purpose products. Ther... More Details >>

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 >>

Terminal indicator lamp

The inverter outputs the peak voltage 300 to 400 VDC of the bus voltage not in a pure sine wave but a in a PWM waveform. Check if the lamp to be connected ca... More Details >>
