Off-line auto-tuning procedure (with motor rotation)
(Note 2) After auto-tuning is completed, be sure to set 01 in H002/H202, otherwise measured data is
not effective.
(Note 3) Speed "X" of above (5) depends on accel/deceleration time. (T: Larger time of accel or
deceleration time)
0 < T < 50 [s] :
X=40%


T < 100 [s] : X=20%

T [s] : X=10%
(Note 4) If auto-tuning is failed, try to execute again.
(Note 5) If the inverter trips during the auto-tuning, the auto-tuning is interrupted. After removing
the cause of trip, retry auto-tuning from the beginning.
(Note 6) If inverter is stopped during auto-tuning by stop command (by STOP key or deactivate RUN
input), measured constants could remain. Be sure to execute auto-tuning again.
(Note 7) If auto-tuning is attempted in free V/f setting, auto-tuning will fail with error display.

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.
(Note 1): When no-rotation setting (
