10. When performing the auto-tuning with one lower size of motor, enable the
overload restriction function, and set the overload restriction level to 150%
of the rated current of the motor.
11. When deceleration over-voltage suppress integral time (b134) is small,
auto-tuning may result in over-voltage trip. In this case, increase b134 and
retry the auto-tuning.
12. To execute auto-tuning, be sure to set the output frequency (F001) larger
than starting frequency (b082) regardless with or without rotation.

When no-rotation setting (H001=01), (4) and (5) are skipped.
After auto-tuning is completed, be sure to set 02 in H002/H202, otherwise
measured data is not effective.
Speed "X" of above (5) depends on accel/deceleration time.
(T: Larger time of accel or deceleration time)
0 < T < 50 [s] :
50 ≤ T < 100 [s] :
100 ≤ T [s] :
If auto-tuning is failed, try to execute again.

Auto-tuning starts
When RUN cmd. is given, the motor runs according to
following steps.
(1) 1st AC excitation (no rotation)
(2) 2nd AC excitation (no rotation)
(3) 1st DC excitation (no rotation )
(4) V/f operation (80% of base freq.)
(5) SLV operation (X % of base freq.)
(6) 2nd DC excitation (no rotation)
(7) Displays the result.
