Click steps to track your progress.
Re-enter the known password carefully, ensuring no digits are mistyped and verifying the numerical value.
If the password is unknown, refer to the plant's documentation or the drive's default password (often '0', or four-digit default specified in manual).
Attempt to reset the password by setting Parameter 16-00 (Access code) to '0' (User defined) and then changing the password if access is possible.
If unable to access, consider performing a factory reset (e.g., Parameter 14-22, 'Operation Mode') which typically resets all passwords to default, then reconfigure.
If a temporary lockout is suspected, wait for a specified period (e.g., 30 seconds) before re-attempting password entry.
