4.10 Verifying Parameter Settings and Backing Up ChangesCheck changes to parameter settings as a result of Auto-Tuning using the Verify function. Refer to Verifying ParameterChanges: Verify Menu on page 86.Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidentalmodification of parameter settings.u Backing Up Parameter Values: o2-03Performing the following procedure stores all parameters settings to drive memory where they can later be recalled ifnecessary. Set o2-03 to “1” to save parameter changes. This saves all parameter settings, and then returns o2-03 to 0. Thedrive can now “recall” the saved parameters by performing a “user-initialization” (A1-03 = 1110).No. ParameterName Description SettingRange DefaultSettingo2-03 User ParameterDefault ValueAllows storing of parameter settings as a User Initialization Selection.0: Saved/Not set1: Set Defaults - Saves current parameter settings as user default settings.2: Clear All - Clears the currently saved user settings. After saving the user parameterset value, the items of 1110 (User Parameter Initialize) are displayed in A1-03 (UserParameter Default Value).0 to 2 0A1-03 InitializeParametersSelects a method to initialize the parameters.0: No Initialize1110: User Initialize (The user must first program and store desired settings usingparameter o2-03)2220: 2-Wire Initialization (parameter initialized prior to shipment)3330: 3-Wire Initialization5550: oPE4 Fault reset0 to 5550 0u Parameter Access Level: A1-01Setting the Access Level for “Operation only” (A1-01 = 0) allows the user to access parameters A1-oo and Uo-ooonly. Other parameters are not displayed.Setting the Access Level for “User Parameters” (A1-01 = 1) allows the user to access parameters that have been previouslysaved as User Parameters. This is helpful when displaying only the relevant parameters for a specific application.No. ParameterName Description SettingRange DefaultA1-01 Access LevelSelectionSelects which parameters are accessible via the digital operator.0: Operation only (A1-01, -04, and -06 can be set and monitored.

This includesrecently viewed parameters or parameters specifically selected for quick access.If parameter A2-33 is set to 1, recently viewed parameters will be listed between A2-17and A2-32. Parameters A2-01 through 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 UserParameter group. The entire A2 parameter group is now available for manualprogramming.b1-01 too2-08 –A2-33 User ParameterAutomaticSelection0: Parameters A2-01 through A2-32 are reserved for the user to create a list of UserParameters.1: Save history of recently viewed parameters. Recently edited parameters will be savedto A2-17 through A2-32 for quick access. The most recently changed parameter isregistered in A2-17. The second most recently changed parameter is registered in A2-18.0, 1 1u 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 selectedpassword must be entered in parameter A1-04 to unlock parameter access (i.e., parameter setting A1-04 must match thevalue programmed into A1-05). The following parameters cannot be viewed or edited until the value programmed intoA1-04 correctly matches the value as programmed in parameter A1-05: A1-01, A1-02, A1-03, A1-06 and A2-01 throughA2-33.Note: Parameter A1-05 is hidden from view. To display A1-05, access parameter A1-04 and simultaneously depress the key and thekey.4.10 Verifying Parameter Settings and Backing Up Changes108 YASKAWA ELECTRIC SIEP C710606 16C YASKAWA AC Drive – V1000 Technical Manual
