Operation Mode
Hand On The navigation keys on the LCP control the
frequency
converter. Stop commands,
reset,
reversing, DC brake, and other signals applied
to the control terminals can override local
control.
Reference Site
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.
Operation Status
AC Brake
AC Brake was selected in 2-10
Brake Function.
The AC
brake over-magnetizes the motor to
achieve a controlled slow down.
finish OK Automatic motor adaptation (AMA) was
carried out successfully.
ready AMA is
ready to start. Press [Hand On] to start.
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
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*).
The corresponding terminal is not
connected.
•
Coast activated by serial communication
Ctrl. Ramp-down Control Ramp-down was selected in
14-10 Mains Failure.
•
The mains
voltage is below the value set
in 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 4-51 Warning Current
High.
Current Low The frequency converter output current is
below the limit set
in 4-52 Warning Speed Low
DC Hold
DC hold is selected in 1-80 Function at Stop
and
a stop command is active. The motor is
held by a DC current set in 2-00 DC Hold/
Preheat Current.
Operation Status
DC Stop
The motor is held with a DC current (2-01
DC
Brake Current) for
a specified time (2-02 DC
Braking Time).
•
DC Brake is activated in 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*).
The corresponding terminal is not active.
•
The DC Brake is activated via serial
communication.
Feedback high The sum of all active feedback is above the
feedback limit set in 4-57
Warning Feedback
High.
Feedback low The sum of all active feedback is below the
feedback limit set in 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*).
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 until a run
permissive signal is received,
the motor remains stopped.
Freeze ref.
Freeze Reference was chosen as a
function for
a digital input (parameter group 5-1*). 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 until a
run permissive signal is
received via a digital
input, the motor is stopped
Jogging The motor is running as programmed in
3-19 Jog Speed [RPM].
•
Jog
was selected as function for a digital
input (parameter group 5-1*). The
corresponding terminal (for example,
Terminal 29) is active.
•
The Jog function is activated via the serial
communication.
•
The Jog function was selected as a
reaction for a monitoring function (for
example, No signal). The monitoring
function is active.
