Selecting the Advanced magnetic flux vector
control
POINT POINT
• To use the Advanced magnetic flux vector control, set the motor capacity, the number of motor poles, and the motor type
using Pr.80 and Pr.81 .

Advanced magnetic flux vector control
NOTE
• To perform driving in a better accuracy, perform offline auto tuning, then set the online auto tuning, and select Real
sensorless vector control.
• Under this control, rotations are more likely to be uneven than under V/F control. (This control method is not suitable for
grinder, wrapping machine, etc., which require even rotation at a low speed.)
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
