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.
