Password Locked

What does Password locked mean?

An attempt has been made to read or write a parameter that is restricted by a password. This security feature prevents unauthorized modification of critical settings, but the inverter output is not shut off. Access to protected parameters is denied until the correct password is entered.

• Attempting to modify a critical inverter parameter (e.g., motor tuning, protection settings) without entering the correct password.
• Incorrect password entry exceeding a defined number of attempts, leading to a temporary lockout.
• System security policy requiring password entry for read access to sensitive diagnostic data.
• Previous service personnel enabled password protection (e.g., via Pr. 120 Password function selection) and did not record or share the password.
