5.3.5.5 [Fault Record] status details
In the [Fault Record] status, you can view the contents of the recent 8 faults as well as the voltage,
current, preset speed, feedback speed status, U, V, W three-phase current instantaneous value and
fault occurrence time recorded at the time of fault occurrence. In the main status interface,
pressing will display ER0=X, pressing or will switch between ER0 and ER7,
where ER0 indicates the serial number of the recent fault, ER7 indicates the serial number of the
earliest fault, X indicates the code of the fault under the current serial number, below which there is
the fault meaning of the fault code displayed in Chinese. Users can press again in the fault
code display state to display the DC bus voltage (U
dc
), instantaneous value of output current (I
rms
),
current reference frequency (V
ref
), feedback frequency (V
fbk
), instantaneous value of U-phase current
(I
u
), instantaneous value of V-phase current (I
v
) and instantaneous value of W-phase current (I
w
)
recorded under the current fault, and press again to return to the fault code display state.

5.3.5.6 [Self learning] status details
In the self-learning status, self-learning for motor parameters can be conducted manually.
Pressing , there is an additional cursor indicating the modification position on the parameter to
be modified. Then, press or select the self-learning item, press to confirm, and
press the “RUN” key to start self-learing. The meanings of self-tuning selection parameters are as
follows:
0: Normal operation mode
4: Motor static self-learning
Press to return to the previous menu state.
5.3.5.7 [Query of Modified Parameters] status details
You can view the parameters that have been modified via the panel and directly modify the modified
parameters.
