Advanced magnetic flux vector control
·
By setting the capacity, number of poles and type of the motor used in Pr. 80 and Pr. 81, the advanced
magnetic flux vector control can be selected.

Setting Description
9999 V/F control
80
0.4 to 55 Set the motor capacity applied. Advanced magnetic flux vector control
9999 V/F control
2, 4, 6 Set the number of motor poles. Advanced magnetic flux vector control
81
12,14,16
V/F control is selected when the X18 (magnetic flux-V/F
switch-over) signal switches on.
(This selection is not made during operation.)
Use any of Pr. 180 to Pr. 186 to assign the terminal
used for X18 signal input.
12: For 2-pole motor
14: For 4-pole motor
16: For 6-pole motor
·
When using constant-torque motor, set "1" in Pr. 71.
Note: 1. Speed fluctuation is slightly greater than in the V/F control. (Advanced magnetic flux vector
control may not be suitable for machines which attach importance to little speed fluctuation
at low speed, e.g. grinders, lapping machines.)
2. When the terminal functions are changed using Pr. 180 to Pr. 186, the other functions may
be affected. Confirm the functions of the corresponding terminals before making setting.
·
For adjustment of motor speed fluctuation due to load variation
Pr. 89 can be used to adjust motor speed fluctuation when the load varies.
