7.3 Status Messages

When the frequency converter is in Status mode, status
messages are generated automatically and appear in the
bottom line of the display (see Illustration 7.2).

Illustration 7.2 Status Display
Table 7.1 to Table 7.3 describe the displayed status
messages.
Off The frequency converter does not react to any
control signal until [Auto On] or [Hand On] is
pressed.
Auto On The frequency converter is controlled from the
control terminals and/or the serial communi-
cation.
Hand On The frequency converter is controlled by the
navigation keys on the LCP. Stop commands,
reset, reversing, DC brake, and other signals
applied to the control terminals override local
control.
Table 7.1 Operation Mode
Remote The speed reference is given from external
signals, serial communication, or internal
preset references.
Local The frequency converter uses [Hand On]
control or reference values from the LCP.

AC Brake Parameter 2-16 AC brake Max. Current was
selected in parameter 2-10 Brake Function. The
AC brake overmagnetises the motor to achieve
a controlled slow-down.

AMA finish OK Automatic motor adaptation (AMA) was
carried out successfully.
AMA ready AMA is ready to start. Press [Hand On] to start.
AMA running AMA process is in progress.
Braking The brake chopper is in operation. Generative
energy is absorbed by the brake resistor.
Braking max. The brake chopper is in operation. The power
limit for the brake resistor defined in
parameter 2-12 Brake Power Limit (kW) has
been reached.
•
Coast Coast inverse was selected as a function for
a digital input (parameter group 5-1*
Digital Inputs). The corresponding terminal
is not connected.
•
Coast activated by serial communication.
Ctrl. ramp-down [1] Control Ramp-down was selected in
parameter 14-10 Mains Failure.
•
The mains voltage is below the value set
in parameter 14-11 Mains Voltage at Mains
Fault at mains fault .
•
The frequency converter ramps down the
motor using a controlled ramp down.
Current High The frequency converter output current is
above the limit set in parameter 4-51 Warning
Current High.
Current Low The frequency converter output current is
below the limit set in parameter 4-52 Warning
Speed Low.
DC Hold [1] DC hold is selected in
parameter 1-80 Function at Stop and a stop
command is active. The motor is held by a DC
current set in parameter 2-00 DC Hold/Preheat
Current.
DC Stop The motor is held with a DC current
(parameter 2-01 DC Brake Current) for a
specified time (parameter 2-02 DC Braking
Time).
•
The DC Brake cut in speed is reached in
parameter 2-03 DC Brake Cut In Speed [RPM]
and a stop command is active.
•
DC Brake (inverse) is selected as a function
for a digital input (parameter group 5-1*
Digital Inputs). The corresponding terminal
is not active.
•
The DC Brake is activated via serial
communication.
Feedback high The sum of all active feedbacks is above the
feedback limit set in parameter 4-57 Warning
Feedback High.
Feedback low The sum of all active feedbacks is below the
feedback limit set in parameter 4-56 Warning
Feedback Low.
