4.10 Verifying Parameter Settings and Backing Up Changes
Use the Verify Menu to check all changes to parameter settings.
page 94.
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

The 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" 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-
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 been
previously saved as User Parameters. This is helpful when displaying only the relevant parameters for a specific
application.

2: Advanced Access Level. All parameters can be set and monitored.
Parameters selected by the user are saved as User Parameters. This includes recently viewed parameters or parameters
specifically selected for quick access.
A2-01
User Parameters
If parameter A2-33 is set to 1, recently viewed parameters will be listed between A2-17 and A2-32. Parameters A2-01
to
1 to 32 through A2-16 must be manually selected by the user.
A2-32
If A2-33 is set to 0, then recently viewed parameters will not be saved to the group of User Parameters. A2-
parameters are now available for manual programming.
0: Parameters A2-01 through A2-32 are reserved for the user to create a list of User Parameters.
User Parameter
1: Save history of recently viewed parameters. Recently edited parameters will be saved to A2-17 through A2-32 for
A2-33 Automatic
quick access. The most recently changed parameter is saved to A2-17. The second most recently changed parameter is
Selection
saved to A2-18.

◆ Password Settings: A1-04, A1-05

The user can set a password to the drive to restrict access. The password is selected via parameter A1-05. The password
must be entered to A1-04 to unlock parameter access (i.e., parameter setting A1-04 must match the value programmed
into A1-05). The following parameters 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, 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.

Lets the user create a set of default settings for a User Initialization.
0: Saved/Not set
1: Set Defaults - Saves current parameter settings as the default values for a User Initialization.
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).
Selects a method to initialize the parameters.
0: No Initialize
1110: User Initialization (The user must first program and store desired settings using parameter o2-03)
2220: 2-Wire Initialization (parameter initialized prior to shipment)
3330: 3-Wire Initialization
5550: oPE4 Fault reset
