Selection method of advanced magnetic flux vector control
NOTES
Uneven rotation slightly increases as compared to the V/F control. It is not suitable for machines
such as grinding machine and wrapping machine which requires less uneven rotation at low
speed.
When a surge voltage suppression filter (FFR-DT) is connected between the inverter and motor,
output torque may decrease.
Perform secure wiring.
(Refer to section 3.2.)
Set the motor. (Pr. 71)

Set the motor capacity and the number of motor poles.
(Pr. 80, Pr. 81) (Refer to section 6.2.1.)
Set the operation command.
(Refer to section 6.18.1.)
Test run
Set motor capacity (kW) in Pr. 80 "Motor capacity" and the number of motor
poles (number of poles) in Pr. 81 "Number of motor poles".
(V/F control is performed when the setting is "9999" (initial value).
Select the start command and speed command.
1) Start command
–
Operation panel: Setting by pressing the RUN key of the
operation panel
–
External command: Setting by forward rotation or reverse
rotation command (terminal STF or STR)
2) Speed command
–
Operation panel: Setting by pressing the digital dial of the
operation panel
–
External analog command (terminal 2 or 4):
Give a speed command using the analog signal input to
terminal 2 (or terminal 4).
–
Multi-speed command:
The external signals (RH, RM, RL) may also be used to give
speed command.
앫
Perform offline auto tuning. (Pr. 96) (Refer to section 6.8.3.)
Select the control method. (Pr. 800)
(Refer to section 6.3.2.)
Set "20" (initial value) in Pr. 800 to make advanced magnetic flux vector
control valid.
