Waveform improvement

A reference sine wave signal is generated inside the high power factor converter, and transistors are configured and PWM switching is performed in the conver... More Details >>

Protective functions

Protective functions against the power supply fault, overcurrent, element fault, undervoltage, and transistor thermal fault (inverter protection) are availab... More Details >>

Regenerative power flow

If all inverters are in regenerative operation, the regenerative power is regenerated to the power supply. If one of the inverters is power driving, the rege... More Details >>

What happens if the supplied reactor and outside box are not used?

Harmonics cannot be suppressed (controlled) correctly and noise cannot be removed. Be sure to connect the supplied reactor and outside box to the inverter. More Details >>

Harmonic Suppression Guidelines

The harmonics generation device manufacturer application form must be created by the manufacturer and submitted by the consumer when a device that contains a... More Details >>

FR-A5CN03

Since the heat sink and fan are not waterproof, you need to enclose them so that they are not exposed to the spray of water. If you use the inverter (heat si... More Details >>

Current measurement method

When measuring current, if you open the output side while current is flowing on the input side, high voltage is induced and dielectric breakdown may occur wi... More Details >>

Inverter control power supply

The FR-E540 uses common input for the control power supply and main circuit power supply. (It has only one power supply input terminal.) Therefore, you canno... More Details >>
