4.11 Verifying Parameter Settings and Backing Up Changes
Use the Verify Menu to check all changes to parameter settings. Refer to Verifying Parameter Changes: Verify Menu on
page 110 .
Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidental modification
of parameter settings.
u 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.

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

Parameters
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
3410: HVAC Initialization
3420: OEM Bypass Initialization

u 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.

Parameters selected by the user are saved as User Parameters, including recently viewed
parameters and 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, recently viewed parameters will not be saved to the group of User Parameters.
A2- parameters are now available for manual programming.

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 saved to A2-17. The
second most recently changed parameter is saved to A2-18, etc.

u 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, 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 press
OFF
and simultaneously.
