5.1 A: Initialization 5.1 A: Initialization The initialization group contains parameters associated with initial setup of the drive. Parameters involving the display language, access levels, initialization, and password are located in this group. u A1: Initialization n A1-01: Parameter Access Level Allows or restricts access to drive parameters. Setting 0: Operation Only Access is restricted to parameters A1-01, A1-04, and all U monitor parameters. Setting 2: Advanced Access Level (A) and Setup Access Level (S) All parameters can be viewed and edited. Notes on Parameter Access • If the drive parameters are password protected by A1-04 and A1-05, parameters A1-01 and A1-03 cannot be modified.
• If parameters are changed via serial communication the parameters can not be changed from the digital operator until an Enter command is received from the serial communication. n A1-03: Initialization Resets parameter settings back to their original default values. After the initialization the parameter automatically returns to 0. Setting 0: No Initialize No initialization. Setting 2220: 2-Wire Initialization Resets all parameters back to their original default settings with digital inputs S1 and S2 configured as forward run and reverse run, respectively. Setting 3330:
3-Wire Initialization The drive parameters are returned to factory default values with digital inputs S1, S2, and S5 configured as run, stop, and forward/reverse respectively. 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. Table 5.1 Parameters not Changed by Drive Initialization n A1-04, A1-05: Password and Password Setting A1-04 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 Password The 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 to unlock parameter access. Until the correct password is entered, the following parameters cannot be viewed or edited: A1-01 and A1-03. The instructions below demonstrate how to set a new password. Here, the password set is “1234”. An explanation follows on how to enter the password to unlock the parameters. 70 SIEP C710606 33A OYMC AC Drive – J1000 User Manual No. Parameter Name Setting Range Default A1-01 Access Level Selection 0, 2 2 No. Parameter Name Setting Range Default A1-03 Initialize Parameters 0, 2220, 3330 0 No.
