■ MICROMASTER 411/COMBIMASTER 411
The new
MICROMASTER 411/
COMBIMASTER 411 series is
included in Catalogue DA 51.3
which contains the complete
product range with ordering data,
technical details, and explanations.
Fields of application
The MICROMASTER 411 and
COMBIMASTER 411 are the
ideal solution for distributed
drive applications which require
a high degree of protection. The
devices have been designed for
a broad range of drives from
simple individual applications
for pumps and fans up to multiple
conveyor drives in networked
control systems.
The ECOFAST variants for the
frequency converter series
MICROMASTER 411/
COMBIMASTER 411 contain
connectors for the power supply,
communications interfaces,
and motor connections to permit
fast and problem-free replacement
for time-critical applications,
and are completely
compatible with ECOFAST
technology systems.
They are based on the universal
MICROMASTER 420 converter
series and distinguish themselves
through customer-oriented
performance and easy handling.
Design
The modular design makes it
possible to select individual
MICROMASTER 411/
COMBIMASTER 411 products
including accessories, e.g.
electromechanical brake controls
or a PROFIBUS module.
Main characteristics
• Power range:
0.37 - 3.0 kW, 400 V, 3AC
• IP66 degree of protection
(MICROMASTER 411), selfcooling
• Electrical isolation of electronics
and connection terminals
• Parameter sets for fast commissioning
and cost-saving
• Modular construction with
many accessories
• Operation without operator
panel possible (if jumpers
and/or control potentiometers
are used)
• Integrated control potentiometer
which can be accessed
from the outside.
Accessories (overview)
• Basic Operator Panel
(BOP) for parameterizing a
converter
• Clear text Advanced Operator
Panel (AOP) for
MICROMASTER 411 and
COMBIMASTER 411 with multilingual
display
• PROFIBUS module
• AS-Interface module
• DeviceNet module
• REM module (dynamic brake
and control module for electromechanical
brake)
• EM module (electromechanical
brake control module)
• PC connecting set
• Assembly sets for fitting the
operator panel
• PC commissioning programs.
■ ECOFAST
ECOFAST is a system which
permits extensive decentralization
and a modular structure for
installation elements on the
component level
Picture of the ECOFAST system
(MICROSTARTER,
COMBIMASTER 411,
MICROMASTER 411 and motor
connector (Order Code G55),
alternatively EMC resistant motor
connector (Order Code
G56)).
The main advantages of the
ECOFAST motor terminal 1 ) as
compared with a terminal box
are as follows:
• Fast assembly of I/O devices
(e.g. motor starter) belonging
to the ECOFAST system
• Reduction of assembly and repair
times at end user
• No wiring errors due to connector
technology
• Replacement of motor without
affecting the electrics.

found in the Catalogue IK PI and
in the converter catalogue
"Distributed drive solutions
CM411" – DA 51.3
The ECOFAST motor terminal
can be supplied for the following
motors:
• Frame sizes 56 M to 132 M
• Power range 0.06 kW to
5.5 kW (7.5 kW on request)
• Direct on-line-starting:
Voltage code 1 for 230 Vd/
400 V*, 50 Hz
