The nonlinear parameters of the inverter may change when the inverter or the main control
board replaced, self-learning needs to be performed as shown in
Fig. 5-10
.
Fig. 5-10 Flow chart 2 of self-learning
Note: the self-learning flowchart 2 not include the situation of the frequency inverter types changed.
Therefore, please replace the inverter or the main control board with same type, do not involve changes in
the inverter type.
When perform parameters self-learning, the required implementation conditions, the detection
parameters and the motor running state (4-pole variable frequency motor as example) are shown
in
