Setting 0: No Initialize
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.
Refer to Setting 40, 41: Forward Run, Reverse Run Command for 2-Wire Sequence on page 211 for more information on
digital input functions.
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. Refer to Setting 0: 3-Wire Sequence on page 205 for more information on digital input functions.

A1-05 Password Setting
How to Use the Password
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,A1-03,
A1-06, and A2-01 through A2-33.
The instructions below demonstrate how to set password “1234”. An explanation follows on how to enter that password to
unlock the parameters.
