static self learning. To set the parameters according to load conditions, and then press the RUN
button, the inverter will be parameter self learning. Parameters from the learning must be done
in keyboard mode, terminal and communications operation mode cannot be parameter self
learning.
0: No operation, namely parameters self-learning is prohibited.
1: Asynchronous motor parameters of static self learning. Prior to induction motor
parameters of static self learning, it is necessary to properly set b0.00 ~ b0.05 motor type and
motor nameplate parameters. Induction motor parameters of static self learning, inverter can
obtain b0.06 ~ b0.08 three parameters.
2: Asynchronous motor parameter self learning in an all-round way. Induction motor
parameter self learning process, the comprehensive frequency converter for static self learning
first, and then according to the acceleration time F0.13 to motor rated frequency 80%, after a
period of time, in accordance with the deceleration time F0.14 slow down and learn the end.
The motor type and motor nameplate parameters b0.00 to b0.05 should be set correctly before
the induction motor parameters are fully self-learning.
Induction motor parameter self learning comprehensively, inverter can obtain b0.06 ~
b0.10 five motor parameters, vector control current loop F5.12 ~ F5.15 PI parameters.
Note: The motor learning must be done in keyboard mode, terminal and communications
operation mode cannot be machine self-learning.

1, restore the factory Settings, not including motor parameters
Set y0.00= 1, function of frequency converter parameters mostly recovery for the
manufacturer factory, but the motor parameter, frequency instruction decimal point (F0.02) and
fault recording information, total running time, the accumulative electric time, total power
consumption is not restored.
2, remove record information
Remove converter fault recording information, total running time, the cumulative time,
total power consumption.
3, parameter default values, including motor parameters.
4, backup the current user parameters
The parameters set the backup for the current user. The current backup function parameter
setting values all down. To facilitate customer recovery after parameter adjustment disorder.
