6.3 Status Message Definitions
to
describe the shown 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
Control the unit via the navigation keys on
the LCP. Stop commands, reset, reversing, DC
brake, and other signals applied to the control
terminals can override local control.
Table 6.2 Operating 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
AC Brake was selected in
parameter 2-10 Brake
Function
. The AC brake over-magnetizes 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. The brake
resistor absorbs generative energy.
Braking max.
The brake chopper is in operation. The power
limit for the brake resistor 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 Ctrl. 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
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
).
•
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
.
Freeze output
The remote reference is active, which holds
the present speed.
•
Freeze output was selected as a function
for a digital input (
parameter group 5-1*
Digital Inputs
). The corresponding terminal
is active. Speed control is only possible via
the terminal functions speed up and speed
down.
•
Hold ramp is activated via serial communi-
cation.
Freeze output
request
A freeze output command has been given, but
the motor remains stopped until a run
permissive signal is received.
Freeze ref.
Freeze Reference
was selected as a function for
a digital input (
parameter group 5-1* Digital
Inputs
). The corresponding terminal is active.
The frequency converter saves the actual
reference. Changing the reference is now only
possible via terminal functions speed up and
speed down.
Jog request
A jog command has been given, but the
motor remains stopped until a run permissive
signal is received via a digital input.
