4.9.2 Motor Auto-tuning
To obtain the motor parameters, the AC drive can perform dynamic auto-tuning or static
auto-tuning. For the asynchronous motor that cannot be disconnected from the load, you
can input the motor parameters of the same model that was successfully auto-tuned before.
Auto-tuning Application Result
No-load dynamic
auto-tuning
It is applied to applications where the motor (synchronous motor
or asynchronous motor) can be disconnected from the load.
Best
With-load dynamic
auto-tuning
It is applied to applications where the motor (synchronous motor
or asynchronous motor) cannot be disconnected from the load.
OK
Static auto-tuning
It is applied to applications where the motor (asynchronous
motor only) cannot be disconnected from the load and dynamic
auto-tuning is not allowed.
Poor
Manual input
It is applied to applications where the motor (asynchronous
motor only) cannot be disconnected from the load. Input the
motor parameters of the same model that was successfully auto-
tuned before into function codes F1-00 to F1-10.
OK
The following motor auto-tuning description takes motor 1 as an example. The auto-tuning
of motor 2, 3, and 4 is the same and only the function codes are changed correspondingly.
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 F0-02 (Command source selection) to 0 (Operation panel control).
3) Input the motor nameplate parameters (such as F1-00 to F1-05) correctly and input the
following parameters based on the actually selected motor.
Motor Parameter
Motor 1 F1-00: Motor type selection
F1-01: Rated motor power
F1-02: Rated motor voltage
F1-03: Rated motor current
F1-04: Rated motor frequency
F1-05: Rated motor rotational speed
Motor 2 A2-00 to A2-05, dened the same as F1-00 to F1-05
Motor3 A3-00 to A3-05, dened the same as F1-00 to F1-05
Motor 4 A4-00 to A4-05, dened the same as F1-00 to F1-05
For asynchronous motor, set F1-37 (Auto-tuning selection) to 2 (Asynchronous motor
complete auto-tuning). For motors 2, 3, or 4, the corresponding function code is A2-37/ A3-
37/ A4-37. Press
on the operation panel. The operation panel displays:
