Also refer to digital input functions, Setting 0: 3-Wire Sequence on page 236.Setting 5550: oPE04 ResetIf parameters on a certain drive have been edited and then a different terminal block is installed with different settingssaved in its built-in memory, an oPE04 error will appear on the display. To use the parameter settings saved to theterminal block memory, set A1-03 to 5550.Notes on Parameter InitializationThe 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 applicationpreset is selected.Table 5.1 Parameters not Changed by Drive Initialization A1-04, A1-05: Password and Password SettingA1-04 is for entering the password when the drive is locked. A1-05 is a hidden parameter used to set the password.How to use the PasswordThe user can set a password for the drive to restrict access. The password is set to A1-05 and must be entered to A1-04 tounlock parameter access. Until the correct password is entered, the following parameters cannot be viewed or edited:A1-01, A1-02, A1-03, A1-06, A1-07, and A2-01 through A2-32.The instructions below demonstrate how to set a new password. Here, the password set is “1234”.
