9.2.4 Status Messages - Operation Status
Table 95: Operation Status
AC brake was selected in parameter 2-10 Brake Function. The AC brake overmagnetizes the motor to achieve a con-
trolled slow down.
Automatic motor adaptation (AMA) was carried out successfully.
AMA is ready to start. To start, press [Hand On].
AMA process is in progress.
The brake chopper is in operation. The brake resistor absorbs the generative energy.
The brake chopper is in operation. The power limit for the brake resistor dened in parameter 2-12 Brake Power
Limit (kW) has been reached.
[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.
[1] 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.
The drive ramps down the motor in a controlled manner.
The drive output current is above the limit set in parameter 4-51 Warning Current High.
The drive 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 Current.
The motor is held with a DC current (parameter 2-01 DC Brake Current) for a specied time (parameter 2-02 DC Brak-
ing Time).
