5.1 A: Initialization

Notes on Parameter Initialization
The parameters shown in Table 5.1 will not be reset when the drive is initialized by setting A1-03 = 2220 or 3330.
Although the control mode in A1-02 is not reset when A1-03 is set to 2220 or 3330, it may change when an application
preset is selected.
Table 5.1 Parameters not Changed by Drive Initialization
■ A1-04, A1-05: Password and Password Setting
Parameter A1-04 enters the password when the drive is locked; parameter A1-05 is a hidden parameter that sets the
password.
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,
A1-02, 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.
