A1-06: Application Preset
Several 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.

1
Setting 0: Disregarded
A new Run command must be issued after power up. Cycle the Run command to start the drive.
Note:
For safety reasons, the drive is initially programmed not to accept a Run command at power up (b1-17 = 0). If a Run command is issued at
power up, the RUN indicator LED will flash quickly.
Setting 1: Allowed
The motor will start immediately after a power up if a Run command is already enabled.
WARNING! Sudden Movement Hazard. If b1-17 is set to 1 and an external Run command is active during power up, the motor will begin
rotating as soon as the power is switched on. Proper precautions must be taken to ensure that the area around the motor is safe prior to
powering up the drive. Failure to comply may cause serious injury.
