Specification of high-performance vector convertor
4.6 Password settings
Frequency converter provides the user password protection function, when the PP - 00 is set to zero,
is the user's password, exit function code editor state password protection is effective, once again, press
the DATA, will show "-- -- -- -- --", input user password must be correct, can enter ordinary menu,
otherwise unable to enter.
If you want to cancel the password protection function, it is only through the password to enter, and
PP - 00 to 0.

Automatic tuning of motor parameters
Choose the vector control operation mode, in front of the frequency converter operation, must be
accurate input motor nameplate parameters, this frequency converter on the basis of standard motor
nameplate parameters matching parameters; Vector control method of motor parameters dependence is
very strong, to get good control performance, must be charged with the accurate parameters of the
machine.
Motor parameters automatic tuning steps are as follows:
Will first command source (P0-02) choice for operation panel command channel. Then please click
the parameters of the motor under the actual parameter input (according to the current motor choice) :
Motor
selection
Motor 1
Motor 2
If the motor can be completely off load, and then the P1-37 (motor 2 A2 \ to 37) please select 2
(asynchronous machine complete tuning), and then press the RUN key on the keyboard panel, the
inverter will automatically calculate the motor of the following parameters:
Motor
selection
Motor 1
Motor 2
The motor parameters are automatically tuned.
If the motor and the load can not be completely torn off, then P1-37 (motor 2 A2-37) select 1
(asynchronous machine, static tuning) and then press the RUN key on the keyboard panel
