Speed precision of Advanced magnetic flux vector control

The speed precision for each model is as follows:FR-K440 with PG: 1% or less of the maximum speed (3500 rpm)FR-A540 without PG (Advanced flux vector): 1% or ... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Advanced magnetic flux vector control

Check the parameters necessary for tuning again.Check if Pr.9 (Electronic thermal O/L relay) and Pr.81 (Number of motor poles) are set correctly. More Details >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>

Brake sequence function

It can be performed by setting Pr.292 (Automatic acceleration/deceleration) to "8" and Pr.279 (Brake opening current) to 0%. More Details >>
