NOTICE
In auto/remote mode, the drive requires external
commands to execute functions.
Table 9.1 to Table 9.3 define the meaning of the shown
status messages.
Off The drive does not react to any control signal
until [Auto On] or [Hand On] is pressed.
Auto The start/stop commands are sent via the
control terminals and/or the serial communi-
cation.
Hand The navigation keys on the LCP can be used
to control the drive. Stop commands, reset,
reversing, DC brake, and other signals applied
to the control terminals override local control.
Table 9.1 Operating Mode
Remote The speed reference is given from:
•
External signals.
•
Serial communication.
•
Internal preset references.
Local The drive uses reference values from the LCP.

AC brake AC brake was selected in parameter 2-10 Brake
Function. The AC brake overmagnetizes 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. To start, press [Hand
On].
AMA running AMA process is in progress.
Braking The brake chopper is in operation. The brake
resistor absorbs the generative energy.
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 [2] 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] Ctrl. ramp-down was selected in
parameter 14-10 Mains Failure.
•
The mains voltage is below the value set
in parameter 14-11 Mains Fault Voltage Level
at mains fault.
•
The drive ramps down the motor using a
controlled ramp-down.
Current high The drive output current is above the limit set
in parameter 4-51 Warning Current High.
Current low The drive output current is below the limit set
in parameter 4-52 Warning Speed Low.
DC hold 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 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).
•
DC brake is activated 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.
