Frequency setting

Since the Advanced magnetic flux vector control method uses slip compensation to compensate the frequency, the value is not shown as exactly 60 Hz.For V/F co... 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 >>

Can I use the parameter unit FR-PU02?

Yes, but functions are partially limited. (The FR-PU02 cannot demonstrate its full ability. The FR-PU01 cannot be used.) To use the parameter unit FR-PU02, u... More Details >>

Types available for FR-AU03

The FR-AU03 is a dedicated product for the FR-A024. Although it cannot be attached directly to other inverters (FR-A200 and FR-Z, FR-U series), it can be use... More Details >>

Static torque

When a vector inverter is used for position control, the servo lock works when it is stopped. When the start signal (STF or STR) is turned ON, the servo lock... More Details >>

Inverter circuit breaker selection

Since the inverter leakage current is in proportion to the switching voltage of the transistor of the main circuit, the leakage current for the 400 V system ... More Details >>

Fault display

"E.OV3" is displayed when the voltage between the inverter terminals PN rises abnormally high while the inverter is decelerating or stopped. In this case, th... More Details >>
