default parameters restoring. But the detected parameter or recorded value won’t be
restored.
4. For a better parameter protection, the inverter provides password protection to the
parameters. After setting the password (set P07.00 to any non-zero number), the system will
come into the state of password verification firstly after the user press PRG/ESC to come
into the function code editing state. And then “0.0.0.0.0.” will be displayed. Unless the user
input right password, they cannot enter into the system. For the factory setting parameter
zone, it needs correct factory password (remind that the users can not modify the factory
parameters by themselves, otherwise, if the parameter setting is incorrect, damage to the
inverter may occur). If the password protection is unlocked, the user can modify the
password freely and the inverter will work as the last setting one. When P07.00 is set to 0,
the password can be canceled. If P07.00 is not 0 during powering on, then the parameter is
protected by the password. When modify the parameters by serial communication, the
function of the password follows the above rules, too.

1: Sensorless vector control mode 1 (applying to
AM)
No need to install encoders. It is suitable in cases
with high speed control accuracy for accurate
speed and torque control at all power ratings.
2:SVPWM control
No need to install encoders. It can improve the
control accuracy with the advantages of stable
operation, valid low-frequency torque boost and
current vibration suppression and the functions of
slip compensation and voltage adjustment.
Note: AM-Asynchronous motor

The control command of the inverter includes:
start-up, stop, forward, reverse, jogging and fault
reset.
