Footnotes for the preceding table
Note 3 Control method setting A31 to 2 (sensorless vector control) Selected, set carrier frequency(b11) more
than 2.1kHz.
Using motor less than half of the rated capacity, you cannot get enough performance.
Multiple motors cannot be driven by sensorless vector control.
Note 4 To operate the motor over 50/60Hz, consult the motor manufacturer about the maximum
allowablerotation speed. In case of sensorless control mode, it can be 300Hz
Note 5 Inverter frequency could be exceeded 1.5Hz for the maximum frequency[A04] in the case of motor
stabilization is required.
Note 6. The braking torque via capacitive feedback is the average deceleration torque at the shortest
deceleration (stopping from 50/60Hz as indicated). It is not continuous regenerative braking torque.
And, the average deceleration torque varies with motor loss.This value decreases when operating
beyond 50 Hz. If a large regenerative torque is required, the optional regenerative braking resistor
should be used.
