VLT® Decentral Drive FCD 302
Operating Guide
AMA run- AMA process is in progress.
ning
Braking The brake chopper is in operation. Generative energy is absorbed by the brake resistor.
Braking
The brake chopper is in operation. The power limit for the brake resistor defined in parameter 2-12 Brake Power
max.
Limit (kW) has been reached.
Coast
• Coast inverse was selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corre-
sponding terminal is not connected.
• Coast activated by serial communication.
Ctrl. ramp-
[1] Control Ramp-down was selected in parameter 14-10 Mains Failure.
down
•
The mains voltage is below the value set in parameter 14-11 Mains Voltage at Mains Fault.
• The drive ramps down the motor using a controlled ramp down.
Current The drive output current is above the limit set in parameter 4-51 Warning Current High.
High
Current Low
The drive 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 Brak-
ing 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.
• [5] DC-brake inverse is selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corre-
sponding terminal is not active.
• The DC brake is activated via serial communication.
Feedback
The sum of all active feedbacks is above the feedback limit set in parameter 4-57 Warning Feedback High.

Feedback
The sum of all active feedbacks is below the feedback limit set in parameter 4-56 Warning Feedback Low.

Freeze out-
The remote reference is active, which holds the present speed.
put
•
[20] Freeze output is selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corre-
sponding terminal is active. Speed control is only possible via the terminal options [21] Speed up and [22]
Speed down.
• Hold ramp is activated via serial communication.
Freeze out- A freeze output command was given, but the motor remains stopped until a run permissive signal is received.
put request
Freeze ref.
[19] Freeze reference is selected as a function for a digital input (parameter group 5-1* Digital Inputs). The corre-
sponding terminal is active. The drive saves the actual reference. Changing the reference is now only possible via
terminal options [21] Speed up and [22] Speed down.
Jog request A jog command was given, but the motor remains stopped until a run permissive signal is received via a digital
input.
Jogging
The motor is running as programmed in parameter 3-19 Jog Speed [RPM].
