Status Indication

6.3 Status Message Definitions

Table 6.2 to Table 6.4 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.
Table 6.3 Reference Site
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 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.
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.
The sum of all active feedbacks is above the
feedback limit set in parameter 4-57 Warning
Feedback High.
The sum of all active feedbacks is below the
feedback limit set in parameter 4-56 Warning
Feedback Low.
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.
A freeze output command has been given, but
the motor remains stopped until a run
permissive signal is received.
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.
A jog command has been given, but the
motor remains stopped until a run permissive
signal is received via a digital input.
