9.3 Status MessagesWhen the drive is in status mode, status messagesautomatically appear in the lowest line of the LCP display.Refer to Illustration 9.2. Status messages are defined inTable 9.1 – Table 9.3.Status799RPM 7.83A 36.4kW0.00053.2%1(1)AutoHandOffRemoteLocal RampingStopRunningJogging...Stand-by130BB037.111231 Where the stop/start command originates. Refer to Table 9.1.2 Where the speed control originates. Refer to Table 9.2.3 Provides the drive status. Refer to Table 9.3.Illustration 9.2 Status DisplayNOTICEIn auto/remote mode, the drive requires externalcommands to execute functions.Table 9.1 to Table 9.3 define the meaning of the shownstatus messages.Off The drive does not react to any control signaluntil [Auto On] or [Hand On] is pressed.Auto The start/stop commands are sent via thecontrol terminals and/or the serial communi-cation.Hand The navigation keys on the LCP can be usedto control the drive. Stop commands, reset,reversing, DC brake, and other signals appliedto the control terminals override local control.Table 9.1 Operating ModeRemote The speed reference is given from:• External signals.• Serial communication.• Internal preset references.Local The drive uses reference values from the LCP.Table 9.2 Reference SiteAC brake AC brake was selected in parameter 2-10 BrakeFunction. The AC brake overmagnetizes themotor to achieve a controlled slow-down.AMA finish OK Automatic motor adaptation (AMA) wascarried out successfully.AMA ready AMA is ready to start. To start, press [HandOn].AMA running AMA process is in progress.Braking The brake chopper is in operation. The brakeresistor absorbs the generative energy.Braking max. The brake chopper is in operation. The powerlimit for the brake resistor defined inparameter 2-12 Brake Power Limit (kW) hasbeen reached.Coast • [2] Coast inverse was selected as a functionfor a digital input (parameter group 5-1*Digital Inputs). The corresponding terminalis not connected.• Coast activated by serial communication.Ctrl. ramp-down [1] Ctrl. ramp-down was selected inparameter 14-10 Mains Failure.• The mains voltage is below the value setin parameter 14-11 Mains Fault Voltage Levelat mains fault.• The drive ramps down the motor using acontrolled ramp-down.Current high The drive output current is above the limit setin parameter 4-51 Warning Current High.Current low The drive output current is below the limit setin parameter 4-52 Warning Speed Low.DC hold DC hold is selected in parameter 1-80 Functionat Stop and a stop command is active. Themotor is held by a DC current set inparameter 2-00 DC Hold/Preheat Current.DC stop The motor is held with a DC current(parameter 2-01 DC Brake Current) for aspecified time (parameter 2-02 DC BrakingTime).• DC brake is activated in parameter 2-03 DCBrake Cut In Speed [RPM] and a stopcommand is active.• DC brake (inverse) is selected as a functionfor a digital input (parameter group 5-1*Digital Inputs). The corresponding terminalis not active.• The DC brake is activated via serialcommunication.Feedback high The sum of all active feedbacks is above thefeedback limit set in parameter 4-57 WarningFeedback High.Feedback low The sum of all active feedbacks is below thefeedback limit set in parameter 4-56 WarningFeedback Low.Maintenance, Diagnostics, a...
