Axpert-Eazy AC Variable Frequency Drive
6-75
6
Select this when raising the output voltage to near the input voltage, or when the input voltage
changes.
B712 : ACR Feed Forward Selection
=0: Disable =1: Enable
The voltage fluctuation caused by the leakage inductance is feed forward controlled. The current
regulator (ACR) response speed will be increased.
GROUP – 8: M FLUCTUATION COMPENSATION TABLE
B801 ~ B808 : Table Reference Speed 1 ~ 8
This is the reference speed for changing the compensation amount according to the operation speed.
These parameters value will automatically set with Maximum Frequency. Default value as per
50/60Hz.
B809 ~ B816 : Lm Fluctuation Compensation Coefficient 1 ~ 8
This compensates the exciting inductance fluctuation according to the B801 ~ B808 reference speed.
Set the compensation table so that the output voltage is constant during no-load operation through the
entire operation range. This is adjusted with the automatic tuning selection (B201) mode 4 (Extended
rotational) is executed.
