Display unit
The following shows the display unit (LCD display with all display
elements).
The display unit consists of a backlit liquid crystal display (LCD). It
is divided into four areas.

General information on menu navigation
By applying the specified supply voltage to the connection
terminal L2/N and L3 (MMX11), L1 and L2/N (MMX12) or L1,
L2/N and L3 (MMX32, MMX34), the frequency inverter
automatically runs the following functions:
• The lighting of the LCD display is switched on and all segments
are actuated briefly.
• After the self-test, the top status line of the LCD display
indicates that the device is ready to start and proper operation
by an arrow
D under READY.
The arrow under STOP indicates that there is no start command
(FWD or REV).
•The arrow
C in the bottom status line shows the actuation via
control signal terminals with the factory setting on I/O Control
(Control Input/Output). The arrow over FWD (Forward)
indicates the basic rotational direction (phase sequence for a
clockwise rotating field) on the output terminals U/T1, V/T2 and
W/T3).
• Display for the operating data M1.1 and 0.00 Hz (output
frequency) in automatic alternating sequence. The arrow
Y in
the left-hand status line indicates menu level MON (Monitor =
Operating data display).
The frequency inverter is ready for operation and can be started via
the control signal terminal with the specified values from the
factory settings when connecting the allocated motor output (see
Section “Commissioning with control signal terminals (factory
setting)”, page 57).

Area Description
a Status
indicator
The arrowheads (D) on the top border show
information regarding the drive.
• READY = Ready to start
• RUN = Operating notification
• STOP = Stop, stop command activated
• ALARM = Alarm message activated
• FAULT = The drive has been stopped due to
an error message.
b Plain text
display
Two 14- and three 7-segment blocks for
displaying:
• AL = Alarm message
• F = Error messages
• M = Measurement value (operating data)
• P = Parameter numbers
• S = System parameter
•
- = Anticlockwise field of rotation (REV).
The respective units of measurement are
displayed in the bottom line.
c Menu level The arrow Y shows the selected main menu:
• REF = Reference value input (Reference)
• MON = Operational data indicator (Monitor)
• PAR = Parameter levels
• FLT = Fault log (Fault).
d Control
commands
The arrowhead C points to the selected
rotating field direction 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 unit
• BUS = Via fieldbus (interface).
