7.3 Status MessagesWhen the frequency converter is in Status mode, statusmessages are generated automatically and appear in thebottom line of the display (see Illustration 7.2).Status799RPM 7.83A 36.4kW0.00053.2%1(1)AutoHandOffRemoteLocal RampingStopRunningJogging...Stand by130BB037.111 2 31 Operation mode (see Table 7.1)2 Reference site (see Table 7.2)3 Operation status (see Table 7.3)Illustration 7.2 Status DisplayTable 7.1 to Table 7.3 describe the displayed statusmessages.Off The frequency converter does not react to anycontrol signal until [Auto On] or [Hand On] ispressed.Auto On The frequency converter is controlled from thecontrol terminals and/or the serial communi-cation.Hand On The frequency converter is controlled by thenavigation keys on the LCP. Stop commands,reset, reversing, DC brake, and other signalsapplied to the control terminals override localcontrol.Table 7.1 Operation ModeRemote The speed reference is given from externalsignals, serial communication, or internalpreset references.Local The frequency converter uses [Hand On]control or reference values from the LCP.Table 7.2 Reference SiteAC Brake Parameter 2-16 AC brake Max. Current wasselected in parameter 2-10 Brake Function. TheAC brake overmagnetises the motor to achievea controlled slow-down.AMA finish OK Automatic motor adaptation (AMA) wascarried out successfully.AMA ready AMA is ready to start. Press [Hand On] to start.AMA running AMA process is in progress.Braking The brake chopper is in operation. Generativeenergy is absorbed by the brake resistor.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 • Coast inverse was selected as a function fora digital input (parameter group 5-1*Digital Inputs). The corresponding terminalis not connected.• Coast activated by serial communication.Ctrl. ramp-down [1] Control Ramp-down was selected inparameter 14-10 Mains Failure.• The mains voltage is below the value setin parameter 14-11 Mains Voltage at MainsFault at mains fault .• The frequency converter ramps down themotor using a controlled ramp down.Current High The frequency converter output current isabove the limit set in parameter 4-51 WarningCurrent High.Current Low The frequency converter output current isbelow the limit set in parameter 4-52 WarningSpeed Low.DC Hold [1] DC hold is selected inparameter 1-80 Function at Stop and a stopcommand is active. The motor is held by a DCcurrent set in parameter 2-00 DC Hold/PreheatCurrent.DC Stop The motor is held with a DC current(parameter 2-01 DC Brake Current) for aspecified time (parameter 2-02 DC BrakingTime).• The DC Brake cut in speed is reached inparameter 2-03 DC Brake Cut In Speed [RPM]and a stop command 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 an...
