Steps
Operational content
1
Remove the mechanical load from the motor and connect the motor wiring terminals to the output terminals U, V
and W of the frequency inverter correctly. Wiring PG if required according to the control mode.
2
Connect the inverter power terminals R, S, T to the three-phase power supply. Refer to "5.3.2 Preparation of the
induction motor before self-learning" and set the motor type, control mode, carrier frequency, operating speed
range, motor nameplate, etc.
3
Set parameter b0-02 (the motor self-learning mode) to 2 and select full-mode self-learning. The keyboard will
display tUn.
4
Press MULT key on the keyboard to start full-mode self-learning and the keyboard will display tUn--.
5
The self-learning will complete after a period of time which depends on the capacity of the inverter. Thereafter the
keyboard will display tUnEd and blinks for 5s.
6
Check the parameters b1-08 to b1-16 and confirm whether the data is updated.
The detected data in full-mode self-learning are shown in

Note:
During full-mode self-learning, there is voltage in the motor, especially when the cable
between the motor and the frequency inverter is long. So please deal with the grounding and
insulation of the motor well and don’t touch the motor to avoid electric shock. Mechanical load
removed is recommended before perform full-mode self-learning. The rotation speed can reach
80% of the rated speed during self-learning, please be careful when the motor rotates. When the
motor connect with load, the full-load self-learning may can not complete.
