124 YASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual4.10 Verifying Parameter Settings and Backing Up Changes4.10 Verifying Parameter Settings and Backing Up ChangesUse the Verify Menu to check all changes to parameter settings. Refer to Verifying Parameter Changes: Verify Menu onpage 94.Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidentalmodification of parameter settings.◆ Backing Up Parameter Values: o2-03The following procedure saves all parameters settings to drive memory where they can later be recalled. Set o2-03 to “1”to save parameter changes. This saves all parameter settings, and then returns o2-03 to 0. The drive can now “recall” thesaved parameters by performing a User Initialization (A1-03 = 1110).◆ Parameter Access Level: A1-01Setting the Access Level for “Operation only” (A1-01 = 0) allows the user to access parameters A1- and U-only. Other parameters are not displayed.Setting the Access Level for “User Parameters” (A1-01 = 1) allows the user to access only the parameters that have beenpreviously saved as User Parameters. This is helpful when displaying only the relevant parameters for a specificapplication.◆ Password Settings: A1-04, A1-05The user can set a password to the drive to restrict access. The password is selected via parameter A1-05. The passwordmust be entered to A1-04 to unlock parameter access (i.e., parameter setting A1-04 must match the value programmedinto A1-05). The following parameters cannot be viewed or edited until the value entered to A1-04 correctly matches thevalue set to A1-05: A1-01, A1-02, A1-03, A1-06, and A2-01 through A2-33.Note: Parameter A1-05 is hidden from view. To display A1-05, access parameter A1-04 and simultaneously press the key and thekey.No. Parameter Name Description Setting Range Default Settingo2-03 User ParameterDefault ValueLets the user create a set of default settings for a User Initialization.0: Saved/Not set1: Set Defaults - Saves current parameter settings as the default values for a User Initialization.2: Clear All - Clears the currently saved user settings.

This includes recently viewed parameters or parametersspecifically selected for quick access.If parameter A2-33 is set to 1, recently viewed parameters will be listed between A2-17 and A2-32. Parameters A2-01through A2-16 must be manually selected by the user.If A2-33 is set to 0, then recently viewed parameters will not be saved to the group of User Parameters.
