4.11 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 116.It is convenient to check all changes to parameters then save the verified parameters as User parameters.Change the access level or set a password to the drive to prevent accidental modification of parameter settings.u Backing Up Parameter Values: o2-03Setting o2-03 to 1 saves all parameter settings before resetting o2-03 to 0. The drive can now recall all the saved parametersby performing a User Initialization (A1-03 = 1110).No. ParameterName Description SettingRange DefaultSettingo2-03 User ParameterDefault ValuesLets 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 UserInitialization.2: Clear All - Clears the currently saved user settings. After saving the user parameter setvalue, the items of 1110 (User Initialization) are displayed in A1-03 (User Parameter DefaultValue).0 to 2 0A1-03 InitializeParametersSelects a method to initialize the parameters.0: No Initialize1110: User Initialization (The user must first program and store desired settings usingparameter o2-03)2220: 2-Wire Initialization (parameter initialized prior to shipment)3330: 3-Wire Initialization3410: HVAC Initialization3420: OEM Bypass Initialization0 to 3420 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-oo 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 specific application.No. ParameterName Description Setting Range DefaultA1-01 AccessLevelSelectionSelects which parameters are accessible via the HOA keypad.0: Operation only.

Parameters A2-01 through A2-16 must be manually selected by the user.If A2-33 is set to 0, recently viewed parameters will not be saved to the group of UserParameters.

Recently edited parameters will be savedto A2-17 through A2-32 for quick access. The most recently changed parameter is savedto A2-17. The second most recently changed parameter is saved to A2-18, etc.0, 1 1u Password Settings: A1-04, A1-05The user can set a password in parameter A1-05 to restrict access to the drive. The password must be entered to A1-04 tounlock parameter access (i.e., parameter setting A1-04 must match the value programmed into A1-05). The followingparameters cannot be viewed or edited until the value entered to A1-04 correctly matches the value set to A1-05: A1-01, A1-02,A1-03, A1-06, A1-07, and A2-01 through A2-33.Note: Parameter A1-05 is hidden from view. To display A1-05, access parameter A1-04 and press OFF and simultaneously.4.11 Verifying Parameter Settings and Backing Up ChangesYASKAWA ELECTRIC TOEP C710616 45F YASKAWA AC Drive – Z1000 User Manual 1534 Start-Up Programming& Operation
