4. “Default” indicates the value of the function code after it is refreshed while
doing the manipulation of restoring the factory parameters; but the actually
detected parameters or record values cannot be refreshed.

cryptoguard for the function code. After the user’s password is set up (i.e.
user’s password P7.00 parameter is not 0), when the user press PRG/ESC
button to enter function code edit status, the system first enters the user’s
password verification status, displaying “-----“, and the operator must input
correctly the user’s password, otherwise it is impossible to enter. For the
parameters that are factory set up, can enter only if a correct factory password
is input as required. (Here remind user DO NOT try to modify the factory
parameters, and if the parameters are not set up properly, it can cause inverter
malfunction or even damage.) At the state that the cryptoguard is not locked, the
user’s password can be modified at any time, and the one finally input will be the
user’s password. If P7.00 is set as 0, the user’s password can be cancelled;
when the power is on, if P7.00 is not 0, parameters are protected by password.
When serial communication is used to modify the function parameters, the
function of user’s password also fellows above rule.
