It is divided into four areas.Areas of the LCD DisplayGeneral Information on Menu NavigationBy applying the specified supply voltage to the connectionterminals L2/N and L3 (MMX11), L1 and L2/N (MMX12) orL1, L2/N and L3 (MMX32, MMX34), the frequency inverterautomatically runs the following functions:● The lighting of the LCD display is switched on and allsegments are actuated briefly● After the self-test, the top status line of the LCD displayindicates that the device is ready to start and properoperation by an arrow under READY. The arrow underSTOP indicates that there is no start command (FWD orREV)● The arrow in the bottom status line shows the actuationvia control signal terminals with the factory setting on I/OControl (Control Input/Output). The arrow over FWD(Forward) indicates the basic rotational direction (phasesequence for a clockwise rotating field) on the outputterminals U/T1, V/T2 and W/T3)● Display for the operating data M1.1 and 0.00 Hz (outputfrequency) in automatic alternating sequence. The arrowin the left-hand status line indicates menu level MON(Monitor = Operating data display)Operational Data Indicator (Operational)The frequency inverter is ready for operation and can bestarted via the control signal terminal with the specifiedvalues from the factory settings when connecting theallocated motor output (see “Commissioning with ControlSignal Terminals (Factory Setting)” on Page 52).Area Description1 StatusindicatorThe arrowheads ( ) on the top border showinformation regarding the drive:READY = Ready to startRUN = Operating notificationSTOP = Stop, stop command activatedALARM = Alarm message activatedFAULT = The drive has been stopped due to an errormessage2 Plain textdisplayTwo 14- and three 7-segment blocks for displaying:AL = Alarm messageF = Error messagesM = Measurement value (operating data)P = Parameter numbersS = System parameter- = Anticlockwise field of rotation (REV)The respective units of measurement are displayed inthe bottom line3 Menu level The arrow shows the selected main menu:REF = Reference value input (reference)MON = Operational data indicator (monitor)PAR = Parameter levelsFLT = Fault log (Fault)4 ControlcommandsThe arrowhead points to the selected rotating fielddirection and the active control level:FWD = Clockwise rotating field (forward run)REV = Counterclockwise rotating field (reverse run)I/O = Via control terminals (input/output)KEYPAD = Via control unitBUS = Via fieldbus (interface)RUN STOP ALARM FAULTREADYREFFWD REV I/O KEYPAD BUSMONPARFLT1423By actuating the OK button, you can set thealternating display mode to stay on the outputfrequency (0.00 Hz).RUN STOP ALARM FAULTREADYREFFWD REV I/O KEYPAD BUSMONPARFLTDisplay in Automatic AlternationRUN STOP ALARM FAULTREADYREFFWD REV I/O KEYPAD BUSMONPARFLTOK
