● Motor static self-learning: suitable for occasions where it is difficult to separate the motor from the load
and dynamic tuning operation is not allowed
1. Accurately input the motor nameplate parameters: F2.00～F2.06;
2. Write parameter F2.22 as 1 , then press Run to run the inverter;
3. The words " -TUN-" appear on the panel, and the learning is completed;
● Motor dynamic self-learning: suitable for occasions where the motor is easily separated from the
application system :
1. Accurately input the motor nameplate parameters: F2.00～F2.06;
2. Write parameter F2.22 as 2, then press Run to run the inverter ;
3. The words " -TUN-" appear on the panel, and the learning is completed;
Notice
1. When performing parameter self-learning, the motor parameters must be entered correctly
according to the motor nameplate, otherwise the motor parameter self-learning may be
inaccurate.
2. During the motor parameter self-learning process, the learning process can be terminated by
pressing the STOP button , but it may cause incomplete motor parameter self-learning results.
3. During the self-learning process of the motor parameters, if there is an abnormality, it will report
a poor self - tuning fault ( E.tE ).
