4.9.2 Motor Auto-tuning
The methods for the AC drive to obtain the internal electrical parameters of the controlled
motor are: dynamic auto-tuning, static auto-tuning 1, static auto-tuning 2 and manual input.
All auto-tuning methods are applied to asynchronous motor only.
Auto-tuning Application Result
No-load dynamic
auto-tuning
It is applied to applications where the motor can be
disconnected from the load.

auto-tuning
It is applied to applications where the motor cannot be
disconnected from the load.
2.
Static auto-tuning 1
It is applied to applications where the motor cannot be
disconnected from the load and dynamic auto-tuning is not
allowed. Auto-tuning of F1-09 and F1-10 is not required and
use their default value.
Poor
Static auto-tuning 2
It is applied to applications where the motor cannot be
disconnected from the load and dynamic auto-tuning is not
allowed. All motor parameters require auto-tuning.
Better
Manual input
It is applied to applications where the motor cannot be
disconnected from the load. Input the motor parameters of the
same model with successful auto-tuning into function codes
F1-00 to F1-10.
2.
The following part takes motor 1 as an example to describe motor auto-tuning. The auto-
tuning of motor 2 is the same and only the function codes are changed correspondingly.
The motor auto-tuning procedure 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.

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.

F1-00: Motor type selection
F1-01: Rated motor power
F1-02: Rated motor voltage

4) Set F1-37 (Auto-tuning selection) to 2 (Dynamic auto-tuning). For motor 2, the
corresponding function code is A2-37. Press
