• P.294 is a parameter which can decrypt, after decryption succeed, the value of P.294 is 0. When
P.295 is after setting a password-protected, P.294 enters the pre-set the password to unlock the
password-protected parameter, then the parameters can modify.
• P.295 is a parameter which can set password. The password must be larger than 1, after succeeding
to set password, the value of P.295 is 1, and after removing the password, the value of P.295 is 0. If
the password was set, the parameters would not be changed except P.294, and can’t execute P.998.
After cutting off the power, the password also exists. Only when
deciphering is successful, that
parameters can be changed.
Note: If the password was forgotten, the inverter must return to factory to decipher.
