When the frequency converter is in status mode, status
messages are generated automatically from within the
frequency converter and appear in the bottom line of the
display (see Figure 7.1.)
Figure 7.1 Status Display
a. The first part of the status line indicates where
the stop/start command originates.
b. The second part of the status line indicates where
the speed control originates.
c. The last part of the status line gives the present
frequency converter status. These show the
operational mode the frequency converter is in.
NOTE!
In auto/remote mode, the frequency converter requires
external commands to execute functions.
