< 1> When the rated power of the motor P4-01<=30KW, P4-4 is 2 decimal points, and when
P4-01>30KW, it is 1 decimal point.
The above function codes are the parameters on the motor nameplate. Whether V/F or vect-
or control is used, the relevant parameters need to be set accurately according to the motor
nameplate.
In order to obtain better V/F or vector control performance, motor parameter tuning is require-
d, and the accuracy of the tuning result is closely related to the correct setting of the motor
nameplate parameters.

< 1> When the rated power of the motor P4-01>30KW, P4-4 is 1 decimal point, and when P4-
01<=30KW, it is 2 decimal points

=30KW, the decimal point is shown in the table
P4-07~P4-11 function code parameters are generally not on the motor nameplate and need
to be obtained through inverter tuning. Among them, "static tuning" can only obtain three par
-
ameters of P4-07~P4-09, and "rotary tuning" can obtain all 5 parameters. value of a function
code.
Note:
After modifying P4-01, the values of motor parameters P4-02~P4-11 will change accordingly.
