n A1-03: Initialize Parameters
Resets parameters to default values or performs an Application Preset for fan or pump applications. After initialization, the
setting for A1-03 automatically returns to 0.
No. Parameter Name Setting Range Default
A1-03 Initialize Parameters
0, 1110, 2220, 3330, 5550,
6008, 6009, 7770, 7771
0
Setting 1110: User Initialize
Resets parameters to the values selected by the user as User Settings. User Settings are stored when parameter o2-03 is set to
“1: Set defaults”.
Note: User Initialization resets all parameters to a user-defined set of default values previously saved to the drive. Set parameter o2-03 to 2 to
clear the user-defined default values.
Setting 2220: 2-Wire Initialization
Resets parameters to default settings with digital inputs S1 and S2 configured as Forward run and Reverse run, respectively.
Setting 3330: 3-Wire Initialization
Resets parameters to default settings with digital inputs S1, S2, and S5 configured as Run, Stop, and Forward/Reverse
respectively.

Notes on Parameter Initialization
The parameters shown in Table i.20 will not be reset when the drive is initialized by setting A1-03 = 2220 or 3330.

Setting 5550: Terminal/Control Initialize
An oPE04 error appears on the digital operator when a terminal block with settings saved to its built-in memory is installed
in a drive that has edited parameters. Set A1-03 to 5550 to use the parameter settings saved to the terminal block memory.
Application Presets are available to facilitate drive setup for commonly used applications. Selecting one of these Application
Presets automatically assigns functions to the input and output terminals and sets a predefined group of parameters to values
appropriate for the selected application.
In addition, the parameters most likely to be changed are assigned to the group of User Parameters, A2-01 through A2-16.
User Parameters are part of the Setup Group, which provides quicker access by eliminating the need to scroll through multiple
menus.
