Selection of motor rotation during auto-tuning
In the Auto-tuning Selection (H001), select whether or not to rotate the motor during auto-tuning.
3
Auto-tuning
Select the target control for auto-tuning in the 1st/2nd Control Method. To switch to the 2nd con-
trol, allocate one of Multi-function Input S1 to S7 Selection (C001 to C007) to 08 (SET).
Then, turn ON the RUN command based on the setting in the 1st/2nd RUN Command Selection
(A002/A202). The inverter starts auto-tuning operation.
If auto-tuning is completed successfully, the auto-tuning result will be set to the parameters
H030/H230 to H034/H234.
1) 1st AC excitation (Motor does not rotate.
*1
)
2) 2nd AC excitation (Motor does not rotate.
*1
)
3) 1st DC excitation (Motor does not rotate.
*1
)
4) V/f control operation (Motor rotates up to 80% of base frequency.)
*2
5)
Sensorless vector control operation (Motor rotates up to X%
*3
of base frequency.)

6) 2nd DC excitation (Motor does not rotate.
*1
)
7) Auto-tuning result is displayed.
*4
*1. However, the 4-pole motor, for example, may rotate by approximately up to 1/8 of a rotation (half the inverse
of poles).
*2. Steps 4 and 5 will be skipped in auto-tuning without motor rotation (H001 = 01).
*3. The motor speed X in step 5 is given as follows, where T is the acceleration or deceleration time in step 4,
whichever is greater.
*4. The auto-tuning result will be displayed as follows.
If auto-tuning is aborted due to an error, retry it.
To clear the display, press the STOP/RESET key.

Description
Motor does not
rotate (01)
Measures motor parameter values without rotating the motor. Use this setting if you do not
rotate the motor. Because the motor does not rotate, the Motor Parameter Io (No-load cur-
rent) and Motor Parameter J (Moment of inertia) values cannot be measured.
Motor rotates (02)
Measures motor parameter values with the motor rotating. Use this setting if you can rotate
the motor without any problem.
