Operation Description
status
AC brake
AC brake was selected in parameter 2-10 Brake Function. The AC brake overmagnetizes the motor to achieve a con-
trolled slow down.
AMA finish Automatic motor adaptation (AMA) was carried out successfully.
OK
AMA ready AMA is ready to start. To start, press [Hand On].
AMA run- AMA process is in progress.
ning
Braking The brake chopper is in operation. The brake resistor absorbs the generative energy.
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
• [2] 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.
• No output from the drive to the motor.
Ctrl. ramp- [1] Ctrl. 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 in a controlled manner.
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 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 Brak-
ing 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 corre-
sponding terminal is not active.
• The DC brake is activated via serial communication.
Feedback
The sum of all active feedback is above the feedback limit set in parameter 4-57 Warning Feedback High.
high
Feedback
The sum of all active feedback is below the feedback limit set in parameter 4-56 Warning Feedback Low.
low
Freeze out- The remote reference is active, which holds the present speed.
put
• [20] Freeze Output was 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 functions speed up and speed
down.
• Hold ramp is activated via serial communication.
