：
static auto tuning
If the load can not be unconnected from motor, user can adopt static auto
tuning.
First set F3.05 to 1, after confirmation, then press the RUN key on the Keypad, inverter
will perform
static
auto-tuning functions.
2
：
overall auto- tuning
First set F3.05 to 2, after confirmation, then press the RUN key on the Keypad, inverter will
perform overall auto-tuning functions. The overall auto- tuning includes
static auto tuning and
spinning auto tuning and the load must be unconnected form the motor.
Note:
a.
If over-current or over-voltage fault occurs during tuning process, user can adjust
Add/Dec time (P0.16, P0.17) and torque boost (P4.07);
b.
Do not start tuning with load on motor;
c.
Make sure the motor is in stopping status before tuning, otherwise, the tuning can not be
performed normally;
d.
Motor auto-tuning can only be performed in keypad control mode (P0.01=0).

Factory settings of P3.06~F3.10 are the parameters of motor that rated power matches
the inverter. If user already knows the motor's parameters, just input the motor parameters
directly. However, after successfully performing motor auto-tuning, value of P3.06~P3.10
will be updated automatically.
Resistance and inductance are the relative value of the nominal motor parameters.
Resistance value=(real Resistance value )*

Inductance value=(real Inductance value )*2*3.14*P*(1.732*I)/V

In above formular
，
V is motor rated voltage defined by P3.01 ; I is motor rated current
defined by P3.02 ; Pis the motor rated frequency defined by P3.03.
These parameters are reference parameters for vector control, which will affect control
performance directly.
