Auto-tuning Mode Application Result Parameter Setting
Static auto-tuning (incomplete)
It is applied to applications where the motor cannot
be disconnected from the load and dynamic auto-
tuning is not allowed.
OK b0.04 = 1
The process of motor auto-tuning is as follows:
1. If the motor can be disconnected from the load, disconnect the motor from the load mechanically after power-
off so that the motor can run without load.
2. After power-on, set bF.04 (command source selection) to 0 (operation panel control).
3. Input the motor nameplate parameters (such as A0.01 to A0.05) correctly and input the following parameters
according to the motor you select.
Manual Input Parameters
A0.00: Motor type selection
A0.01: Rated motor power
A0.02: Rated motor voltage
A0.03: Rated motor current
A0.04: Rated motor frequency
A0.05: Rated motor speed
4. If the motor can be disconnected from the load completely, set b0.04 to 2 (dynamic auto-tuning for
asynchronous motor). Press the ENTER key. The operation panel displays:
5. Then press the RUN key on the operation panel. The AC drive will drive the motor to accelerate/decelerate
(based on the acceleration time and deceleration time set in b4.06 and b4.07), and the RUN indicator is ON.
When the preceding display information disappears and the operation panel returns to the normal parameter
display status, it indicates that the auto-tuning is completed.
The following motor parameters will be obtained from the auto-tuning.
Motor Parameters Obtained From Auto-tuning
F0-00: Stator resistance (asynchronous motor)
F0-01: Rotor resistance (asynchronous motor)
F0-02: Leakage inductive reactance (asynchronous motor)
F0-03: Mutual inductive reactance (asynchronous motor)
F0.04: No-load current (asynchronous motor)
If the motor cannot be disconnected from the load, set b0.04 (auto-tuning selection) to 1 or 3 (recommended).
When b0.04 = 3, all required motor parameters can be obtained but the auto-tuning process is a littile longer.
