4.10 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 143.
It is convenient to check all changes to parameters then save the verified parameters as User parameters.
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.

Description Setting Range Default Setting
o2-03 User Defaults
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)

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 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 changed
parameters and parameters specifically selected for quick access.
If parameter A2-33 is set to 1, changed 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-oo parameters are now available for manual programming.

0: Parameters A2-01 through A2-32 are reserved for the user to create a group 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 saved
to A2-17. The second most recently changed parameter is saved to A2-18, etc.

<1> When User Parameters are set to parameters A2-17 and higher, all parameters after the last listed parameter will be listed.
Example: When User Parameters are listed from A2-01 to A2-20, the next parameter A2-21 and higher will be listed.
