Please prepare it according to the parameters listed in above table. Motor parameters
self-learning can be performed by setting the parameter b0-02 (the motor self-learning mode)
after the preparation work is completed.
5.3.3 Instructions of induction motor DC self-learning mode
The direct current mode self-learning of the induction motor does not need to separate the motor
from the load or the mechanical brake. It mainly detects the primary side resistance of the motor,
the motor wiring resistance (b1-08 or b2-08), the nonlinear parameters of the frequency inverter,
etc. Just the primary side resistance of the motor can be observed and debugged, the
observations of other parameters require authorization.
The operational procedure of the DC mode self-learning as shown in
Table 5-3
:
Table 5-3 DC mode self-learning procedure
Steps
Operational content
1
Connect the motor terminals to the inverter output terminals U, V, W.
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 (motor self-learning mode) to 1, select DC mode self-learning and the keyboard will display
tUnd.
4
Press the MULT button on the keyboard to start the DC 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 5 seconds.
6
Check the parameter b1-08 or b2-08 to confirm whether the data is updated.
