Advanced magnetic flux vector control

It can be used with the FR-A700 and FR-E700 series. More Details >>

Vector control of the inverter

The speed fluctuation ratio under Advanced magnetic flux vector control of the FR-A500 is as follows. Without encoder: ±1% With encoder (with A5AP): ±0. 02 %... More Details >>

Notes on using single-phase 200 V

With the single-phase 200 V input specifications, the input cable current increases. Therefore, choose larger power supply capacity and NF/MC than three-phas... More Details >>

Built-in reactor

The reactor built in the FREQROL-A201 series is intended to stabilize operation of the converter circuit and differs from the FR-BAL. Note that when performi... More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Direct driven start by power supply

The warning "Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter." is indicated in the precautions at the be... More Details >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Countermeasure against harmonics

Perform calculation given in the harmonic suppression guidelines, and if the limit value is exceeded, you may also need to insert the ACL. Note that you cann... More Details >>

Installing magnetic contactor on input side of inverter

Basically, there is no difference between the A200 and A500. For safer use, from the A500, it is recommended to completely shut off the power supply by turni... More Details >>
