Frequency inverters

M-Max™Description
Application
The frequency inverters of the
M-Max™ series allow a continuously
variable speed control of three-phase
asynchronous motors. They are
specially suited for applications in
which ease of handling and cost-
effectiveness have a high priority.
The characteristics-controlled volt-
age/frequency (U/f) control already
allows a wide range of applications
even with the default settings: from
simple pump and fan drives, standard
packaging applications to the
operation of multiple motors in
horizontal transportation and
conveying.
With sensorless vector control, an
individual drive can also be used in
demanding applications, in which a
high torque and concentricity in the
lower speed range are vital, such as in
the plastics and metal industries, the
textile, paper and printing industries or
in crane and elevator systems.
Rated operational currents from 1.4 to
21 A allow the operation of standard
four-pole asynchronous motors in an
assigned rating range of:
• 0.25 to 2.2 kW at 230 V
(single-phase mains connection),
• 0.25 to 2.2 kW at 230 V
(three-phase mains connection),
• 0.37 to 7.5 kW at 400 V
(three-phase mains connection).
Features
• Compact design through state-of-
the-art IGBT modules

• 6 digital inputs (24 V DC) for sink-
and source-type control
• 2 relays (1 changeover contact,
1 normally open contact, 230 V)
• 1 transistor output (N/O or N/C,
48 V DC)
• 2 analog inputs (0 to +10 V, 4 to
20 mA), selectable and scaleable
• 1 analog output (0 to +10 V),
scaleable

RTU)
• Built-in braking transistor with size
MMX34…
• Optional fieldbus connection
(CANopen, PROFIBUS-DP,
DeviceNet)

CE, UL, c-UL and c-Tick
Functions
A comprehensive range of protection
functions allow safe operation and the
protection of frequency inverter, motor
and application. They offer protection
against:
• Overcurrent, ground fault
• Overload (electronic motor
protection)
• Overtemperature
• Overvoltage, undervoltage
Further functions are:
• Restart inhibit
• U/f control or sensorless vector
control
• Double starting current and
1.5 times overcurrent
• PID controller
• Sequence control
• Braking control (DC braking)
• 8 fixed frequencies
• Electronic motor potentiometer
• Logic function (AND, OR, XOR)
• Upper and lower frequency and
current limits
• Frequency hopping (frequency
masking)
• DC braking before start and up to
motor standstill
• 2 parameter sets
Documentation
An instructional leaflet and a CD are
included with each frequency inverter
of the M-Max™ series.
The instructional leaflet is a quick
guide with illustrations and notes in
23 languages about the correct
handling, mounting and electrical
connection of the device. The CD
contains the instructional leaflet as
well as the Hardware and Engineering
manual in several languages.
The current documentation is also
available for download from
