Fig. 6-4: Selection method of general-purpose 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.

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).
Set "30" (initial value) in Pr. 800 to make general-purpose magnetic flux
vector control valid.
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.
