Output voltage measurement

The inverter's output voltage is controlled by switching DC voltage and has a pulse voltage waveform.(It is not a clean sine wave.)Therefore, it cannot be me... More Details >>

Monitoring function of the FR-A800-R2R

No, they cannot be monitored when Pr.363 is other than "5". They are enabled only when Pr.363 = 5. More Details >>

Noise filter

Noise filtering and harmonics suppression are different matters and you need to install the line noise filter (FR-BSF01) against noise and DCL (FR-BEL) again... More Details >>

Operation of the motor with a brake

For the general-purpose inverter, the motor stop cannot be detected accurately because the actual motor speed from a motor is not input. In general, the RUN ... More Details >>

Deceleration overvoltage (E.OV3)

While the FREQROL-Z200 series and A500 series have a brake resistor built in the capacity up to 7.5K, the FREQROL-E500 series does not have a built-in brake ... More Details >>

FR-CV

Use the FR-HC to suppress harmonics. It also supports power supply regenerative driving.The FR-CV and FR-RC are both power supply regeneration units.The diff... More Details >>

MM-EFS

Carbon steel (S45C) is used for both P1 (outdoor) and no P1 (indoor). More Details >>

Countermeasure against error

The inverter alarm "OV3" occurs when the main circuit DC voltage inside the inverter goes higher than the preset value due to the regenerative power returned... More Details >>

EMC filter

A capacitive filter and common mode choke are built in. (A common mode choke is built in only for the 55K or lower.) Use a connector for whether to turn ON o... More Details >>

USB version

Ver1.1 (Ver2.0 (full speed) compatible). USB1.1 supports Full Speed (12 Mbps) and Low Speed (1.5 Mbps) transmission speed modes. USB2.0 supports High Speed (... More Details >>
