4.9 Verifying Parameter Settings and Backing Up Changes
4.9 Verifying Parameter Settings and Backing Up Changes
Check changes to parameter settings as a result of Auto-Tuning using the Verify function. Refer to Verifying Parameter
Changes: Verify Menu on page 82 .
Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidental
modification of parameter settings.
◆ Backing Up Parameter Values: o2-03
Performing the following procedure stores all parameters settings to drive memory where they can later be recalled if
necessary. 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” the saved parameters by performing a “user-initialization” (A1-03 = 1110).
◆
Parameter Access Level: A1-01
Setting 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 parameters that have been
previously saved as User Parameters. This is helpful when displaying only the relevant parameters for a specific
application.

Default Value
Allows storing of parameter settings as a User Initialization Selection.
0: Saved/Not set
1: Set Defaults - Saves current parameter settings as user default settings.
2: Clear All - Clears the currently saved user settings. After saving the user parameter
set value, the items of 1110 (User Parameter Initialize) are displayed in A1-03 (User
Parameter Default Value).

Parameters
Selects a method to initialize the parameters.

1110: User Initialize (The user must first program and store desired settings using
parameter o2-03)
2220: 2-Wire Initialization (parameter initialized prior to shipment)

Parameters selected by the user are stored to the User Parameter menu. This includes recently
viewed parameters or parameters specifically selected for quick access.
If parameter A2-33 is set to 1, recently viewed parameters will be listed between A2-17 and
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 User Parameter
group. The entire A2 parameter group is now available for manual programming.

0: Parameters A2-01 through A2-32 are reserved for the user to create a list of User
Parameters.
1: Save history of recently viewed parameters. Recently edited parameters will be saved to
A2-17 through A2-32 for quick access. The most recently changed parameter is registered in
A2-17. The second most recently changed parameter is registered in A2-18.
