1.4.2 The Start-up Wizard
The built-in wizard menu guides the installer through the
set-up of the adjustable frequency drive in a clear and
structured manner to set up an open-loop application. An
open-loop application is here an application with a start
signal, analog reference (voltage or current) and optionally
also relay signals (but no feedback signal from the process
applied).
