4.6 Verifying Parameter Settings and Backing Up Changes
Use the Verify Mode to check all changes to parameter settings. Refer to Verifying Parameter Changes: Verify Mode on
page 92 .
Save the verified parameter settings. Change the access level or set a password to the converter to prevent accidental
modification of parameter settings.
◆ Backing Up Parameter Values: o2-03
Setting o2-03 to 1 saves all parameter settings to the converter internal memory. The converter can now recall all 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 only the parameters that have been
previously saved as User Parameters. This is helpful when displaying only the relevant parameters for a specific
application.

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
Initialization) are displayed in A1-03 (User Parameter Default
Value).

1110: User Initialization (The user must first program and store
desired settings using parameter o2-03)

Selects which parameters are accessible via the digital operator.
0: Operation only. A1-01, A1-04, and A1-06 can be set and
monitored, and U- parameters can also be viewed.
