of motor stator resistor, rotator resistor and leakage inductance, while the

parameters of motor mutual inductance and no-load current are not detected.

The parameters of motor mutual inductance and no-load current can be

calculated by the following formula:

IO:motor no-load current

Lm: motor mutual inductance

Lδ: motor leakage inductance

U: motor rated voltage

I: motor rated current

f: motor rated frequency

η: motor power factor

4.2.4 Password Setting

When F7.00 is set to be non-zero, the parameter will be the user’s password.

After exit the function code editing status, the password will be effective after

one minute. And then press the PRGM key again to try to access the function

code editing mode, the inverter panel will display “0.0.0.0”. The password

must be input correctly to access it. If it is necessary to cancel the password

function, set F7.00 to zero.

Notice:

When the inverter is powered on, system will execute initialization first and

inverter panel displays “8000” with four lights on. After initialization, inverter

accesses into stand-by status.
