in a drive that has edited parameters. Set A1-03 to 5550 to use the parameter settings saved to the terminal block memory.
Application Presets are available to facilitate drive setup for commonly used applications. Selecting one of these Application
Presets automatically assigns functions to the input and output terminals and sets a predefined group of parameters to values
appropriate for the selected application.
In addition, the parameters most likely to be changed are assigned to the group of User Parameters, A2-01 through A2-16.
User Parameters are part of the Setup Group, which provides quicker access by eliminating the need to scroll through multiple
menus.
