You can set the general-purpose magnetic flux vector control.
!
General-purpose magnetic flux vector control
Provides large starting torque and sufficient low-speed torque.
If the motor constants vary slightly, stable, large low-speed torque is provided
without specific motor constant setting or tuning.

9999: V/F control
If any of the following conditions are not satisfied, faults such as torque shortage and
speed fluctuation may occur. In this case, select V/F control.
<Operating conditions>
"
The motor capacity is equal to or one rank lower than the inverter capacity.
"
The number of motor poles is any of 2, 4, and 6. (4 poles only for the constant-
torque motor)
"
Single-motor operation (one motor for one inverter) is performed.
"
The wiring length between the inverter and motor is within 30m. (If the length is over
30m, perform offline auto tuning with the cables wired.)
