7.1 Status Display

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 Illustration 7.1.)

Illustration 7.1 Status Display
a. The first word on the status line indicates where
the stop/start command originates.
b. The second word on 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.

Operation mode
The frequency converter does not react to any
control signal until [Auto On] or [Hand On] is
pressed.
The frequency converter is controlled from the
control terminals and/or the serial communi-
cation.
The frequency converter can be controlled by
the navigation keys on the LCP. Stop
commands, reset, reversing, DC brake, and
other signals applied to the control terminals
can override local control.
Reference site
The speed reference is given from external
signals, serial communication, or internal preset
references.
The frequency converter uses [Hand On] control
or reference values from the LCP.
Operation status
AC Brake was selected in 2-10 Brake Function.
The AC brake over-magnetizes the motor to
achieve a controlled slow down.
Automatic motor adaptation (AMA) was carried
out successfully.
AMA is ready to start. Press [Hand On] to start.
AMA process is in progress.
The brake chopper is in operation. Generative
energy is absorbed by the brake resistor.
The brake chopper is in operation. The power
limit for the brake resistor defined in 2-12 Brake
Power Limit (kW) is reached.
