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 >>

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 >>

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 >>

Protective functions

When the protective function works, the inverter is stopped (output shutoff) by the RDY signal. More Details >>

Model configuration

12 models of FREQROL-V200 vector inverters each for the 200 V and 400 V classes from 1.5K to 45K. 9 models of SF-VR vector control dedicated motors each for ... More Details >>

Running frequency, output current

Since the FR-E700 has only one terminal FM, you cannot read two signals simultaneously.Use the optional digital output/additional analog output FR-A7AY.This ... More Details >>

CC-Link

Yes, but the optional kit (FR-A7NC E kit) is necessary. More Details >>

Using a higher grade power factor improving reactor

Using a reactor under a load lighter than the rated capacity slightly spoils its effect in improving the power factor.Therefore, you should use a reactor wit... More Details >>

Power supply ON/OFF

1. It is OK to open MC on the output side while the inverter is operating.2. It is OK to open the input side in case of emergency stop. More Details >>

Current increase at motor stop

If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state.... More Details >>
