Setting 5550: oPE04 Reset
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.
Notes on Parameter Initialization
The parameters shown in
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.

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, A1-07, and A2-01 through A2-32.
The instructions below demonstrate how to set password “1234”. An explanation follows on how to enter that password to
unlock the parameters.
