password to “0000”. Reenter the password to parameter A1-05 after drive initialization.
Enter a setting other than the password (e.g., 0000) in A1-04 to use
the set password to release the lock and restore the lock with
the same password after changing parameter settings.
 A1-06: Application Preset
Several Application Presets are available to facilitate drive setup for commonly used applications. Selecting one of these
Application Presets automatically programs certain parameters to a new set default values and selects the functions for
the I/O terminals that best suit the application. All parameters changed when selecting an Application Preset are also
assigned to the list of User Parameters, A2-01 through A2-16. These can be edited more easily in the Setup Mode and
provide quicker access by eliminating the need to scroll through multiple menus.
Refer to Application Selection on page 114 for details on parameter A1-06.
