1: Stationary auto tuning of Asynchronous motor
When do auto tuning ,motor stationary ,it can get parameter P11.11 ～P11.13。
Static self-learning can not learn all the motor parameters, so the control performance is difficult to achieve the
best; if the motor nameplate information is incomplete, or the motor is not a 4-pole 50Hz GB motor, it is
recommended to perform "rotation self-learning".
In the case of limited rotation, such as limited travel, limited load (crane), limited running direction, etc., static self-
learning is used.
2: Rotational auto tuning of Asynchronous motor
When do auto tuning ,motor first stationary and rotary, ,it can get parameter P11.11～P11.18，as to close loop
control, it can get P10.03 encoder direction
When rotating self-learning, the motor will rotate forward and the speed can reach 50%~100% of the rated speed.
The lighter the load during self-learning, the better the learning effect.
note:
Notice: it can do motor auto tune when command source is keypad
Please self-learn when the motor is cold. Make sure the motor is at rest before learning!
Please confirm that the motor nameplate parameters have been set before self-learning. For closed-loop control,
you should also set the encoder parameters!
After setting this parameter, press the "RUN" button on the keyboard, the self-learning will start, and the inverter
will stop itself after the self-learning is completed.
