4.8 Verifying and Backing Up Parameter SettingsCheck changes to parameter settings using the Verify function. Refer to Verifying Parameter Changes: Verify Menu onpage 66.Save the verified parameter settings. Change the access level or set a password to the drive to prevent accidental modificationof parameter settings.u Parameter Access Level: A1-01Setting the Access Level for “Operation only” (A1-01 = 0) allows the user to access parameters A1-oo and Uo-oo only.Other parameters are not displayed.No. Parameter Name Description SettingRange DefaultA1-01 Access LevelSelectionSelects which parameters are accessible via the digital operator.0: Operation only (A1-01 and A1-04 can be set and monitored. U parameters can bemonitored)2: Advanced Access Level (All parameters can be set and monitored)0, 2 2u Password Settings: A1-04, A1-05The user can set a password to the drive to restrict access. The password is selected via parameter A1-05. The selected passwordmust be entered in parameter A1-04 to unlock parameter access (i.e., parameter setting A1-04 must match the valueprogrammed into A1-05). The following parameters cannot be viewed or edited until the value programmed into A1-04correctly matches the value as programmed in parameter A1-05: A1-01 and A1-03.Note: Parameter A1-05 is hidden from view. To display A1-05, access parameter A1-04 and simultaneously depress the key and thekey.u Copy Function (Optional)Parameter settings can be copied to another drive to simplify parameter restoration or multiple drive setup. The RS-232CInterface Unit (Removable Type) (SI-232/JC) is required to use the following options with J1000 drives:n USB/Copy Unit (JVOP-181)The copy unit is an external option connected to the drive to copy parameter settings to another drive. It includes a USB adapterto connect the drive to a PC.n LED Operator (JVOP-182)The LED operator operates the drive and supports copying, importing, and verifying parameter settings.Note: Use of the LED operator requires that the drive is running drive software version PRG: 1010 or later.n Drive Wizard PlusDrive Wizard Plus is a PC software tool for parameter management, monitoring, and diagnosis. Drive Wizard Plus can load,store, and copy drive parameter settings.
