Verifying Parameter Settings and Backing Up Changes
Use the Verify Menu to check all changes to parameter settings as a result o f Auto-Tuning.
Refer to Verifying Parameter
Changes: Verify Menu on page 85.
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
Setting o2-03 to 1 saves all parameter settings before resetting o2-03 to 0. The drive can now recall all the saved
parameters by performing a User Initialization (A1-03 = 1110).
No.

Lets the user create a set o f 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 A ll - Clears the currently saved user settings. After saving the user parameter set value, the items o f
1110 (User Initialization) are displayed in A 1-03 (User Parameter Default Value).

♦ Parameter Access Level: A1-01
Setting the Access Level for “Operation only” (A1-01 = 0) allows the user to access parameters A 1-D D and U D -D D
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.

♦ Password Settings: A1-04, A1-05
The user can set a password in parameter A1-05 to restrict access to the drive. 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 and A2-01 through A2-33.
N ote: Param eter A1-05 is hidden from view. To display A 1-05, access param eter A 1-04 and press
^ 3 and J simultaneously.
