4.10 Verifying Parameter Settings and Backing Up Changes

Check changes to parameter settings as a result of Auto-Tuning using the Verify function.
Changes: Verify Menu on page
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-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 parameters that have been previously
saved as User Parameters. This is helpful when displaying only the relevant parameters for a specific application.

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 selected
password must be entered in parameter 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 programmed into
A1-04 correctly matches the value as programmed in parameter 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 depress the
key.

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).
Selects a method to initialize the parameters.
0: No Initialize
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)
3330: 3-Wire Initialization
5550: oPE4 Fault reset
Selects which parameters are accessible via the digital operator.
0: Operation only (A1-01, -04, and -06 can be set and monitored. U parameters can be
monitored)
1: User Parameters (Only those recently changed among application parameters A2-01
to -16 and A2-17 to -32 can be set and monitored)
2: Advanced Access Level (All parameters can be set and monitored)
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.
