Cooling concepts electronics
The KEB COMBIVERT F5 modular system provides
mechanical solutions for particularly thermal loads with respect to
inverters and servo controllers, with the aim of optimising heat removal
from the classic control box.
|
|
|
|
Convection Heat Sink
... are particularly compact and the basic version, often
with supporting ventilation, for conventional control box installations of
IP20 protection type devices.
|
|
Push Through Heat Sink
.... reduce heat in the panel by up to 80%, i.e. forms
the basis for compact and tightly sealed cabinets. With the thermal
separation of the heat sink and the installation of the devices in a
two-part panel, heat is shifted to the outside, which leads to better
ambient conditions for the electronic components.
|
|
Flat Rear Heat Sinks
... create an interface for using existing environments,
e.g. thermal connection to the machine or a master heat sink.
|
|
Liquid Cooled Heat Sink
This is a closed cooling system for the design of
hermetically sealed enclosures for challenging ambient conditions. Liquid
cooled heat sinks guarantee the cooling of large power stages also in
conjunction with liquid cooled motors.
|
|
|
|
Supply and regenerative units
All moving systems have kinetic energy when in
operation. When the motor slows down it acts as a generator and converts the
mechanical energy back into electrical energy, which then is shunted into a
braking resistor that results in heat. The power supply and line
regeneration control R6 provides a solution to balance energy or return
energy to the utility grid.
|
|
|
|
COMBIVERT R6
The kinetic energy of AC motor drives is often an
unutilized energy source.
The compact new product KEB COMBIVERT R6 is designed for power supply and
regenerative operation for inverters and servo systems.
KEB COMBIVERT R6 can be operated at line voltage from 200 - 500 VAC. The
design is modular with a compact commutation choke and EMI filter. In
conjunction with the KEB COMBILINE harmonic filter solutions a sinusoidal
regeneration to the utility grid is achieved.
KEB COMBIVERT R6 has a display to show the energy savings while regenerating
to the grid.
|
|

they are also used for test facilities or test stands.
At present, power ranges of 7.5 kW to 250 kW are available based on
industrial device hardware.
|
|

resistance in case of line-voltage drops.
|
|
|
|

|
|
|
|
Ethernet, EtherCAT, Powerlink, ProfiNET
Ethernet-based solutions use the worldwide expansion of
the IT network technology for industrial applications.
It begins with powerful EtherCAT master implementations in the embedded and
IPC-based controls, continues with the integrated EtherCAT slave versions in
the COMBIVERT H6 multi-axis system, or the current COMBIVERT G6 inverters,
and is rounded off with fieldbus solutions for decentralised I/Os with the
module KEB Remote I/O system for complete automation.
|
|
Profibus, CAN, Sercos, InterBus, DeviceNet, Modbus
Established Fieldbus Connections have long been the
"motor" for advanced concepts of systems and machines in conjunction with
sensors and actuators in the process chain.
With the modular operator system, KEB supports all recognised standards for
the entire bandwidth of inverters and servo systems.
Pluggable functional components make initial equipment and later
retrofitting in the field very easy and flexible.

|
EMC
As the amount of
electronics increases, EMC loading and EMC compatibility is becoming an
increasingly important factor for the operational reliability of machinery
and equipment.
European norms and standards require manufacturers and operators to comply
with a set of EMC limitations.
KEB designs, manufactures and supplies a comprehensive programme for
limiting noise levels created by the mains and motors, and for optimising
operating conditions.
Competent advice and mobile EMC measurement devices support onsite selection
and optimisation - i.e. they warrant reliable compliance with statutory
requirements in a variety of applications.
|
|
|
|
EMC Filter
Variable speed drives with uncontrolled rectifier input
can cause low or high frequency interference on the line that are limited by
the EMC regulations.
Adherence to the standards is ensured with the use of universal EMC filters
for individual interference suppression at the drive controller or as a
central filter, designed for complete installation in a panel.
KEB COMBILINE interference suppression filters are designed for industrial
or residential areas and can be supplied with currents rated up to 1000 A.
Segments:
single filter IT line filter, filter for small leakage currents, 3-phase
central filter, central filter with neutral (4-phase system), combined
input/output filters.
|
|
Harmonic Filter
The low-frequency harmonics resulting from B6 rectifier
switches pose an increasing burden on public grids and must be limited with
expensive and cumbersome compensation facilities.
The KEB COMBILINE harmonic filter is a patented passive component which
provides a connection-ready alternative for original equipment or the
retrofitting of production facilities.
Two models of these compact filters are available:
• standard series with THD (total harmonic distortion) smaller than or equal
to 8%, PWHD smaller or equal to 15% in power settings 4 - 460 A.
• economy series with THD smaller than or equal to 15%, PWHD smaller or
equal to 38%. According to standard EN 12015 (european elevator/escalator
norm) in power settings 2 - 63 A.
Larger power settings can be covered with connecting filters in parallel.
|
|
Sinusoidal Output Filter
The cyclical output voltages of frequency inverters
produce additional losses in motor leads and windings which can
significantly affect the reliability and longevity of motor insulation.
KEB COMBILINE sinusoidal output filters limit stresses to admissible limits
and provide the required protection of lacquer insulation and end
connections particularly for long motor leads and special motors.
The protection offered by sinus filters is particularly important for the
retrofitting of already installed older motors with frequency inverters to
optimise the efficiency of existing systems.
The sinus filter range includes the following versions:
• sinusoidal output filter fmax = 100 Hz
• sinusoidal output filter fmax = 200 Hz
• sinusoidal output filter fmax = 400 Hz
• customer-specific versions for output frequencies up to 1,600 Hz.

Electronic assembly
There are extensive accessories available for each
application requirement .You will receive the PC tool KEB COMBIVIS at no
charge. This software enables you to easily operate, diagnose and optimize
all KEB inverters.The input choke reduces the ripple current and the
harmonics on the mains. The output choke protects the motor windings against
the effects of the chopped output voltage from the inverter. Both products
improve the lifetime of components. The braking resistors are designed for
different duty cycles and turn kinetic energy peaks into heat.

|
|
|
PC-Software KEB COMBIVIS

KEB COMBIVIS 6 is factory-tested with operating systems Windows 2000, XP,
Vista and Windows 7, and has been designed as a free too for the complete
administration of all device adjustments, amongst others.
|
|
Mains Input and Motor Chokes
The B6 rectifier input circuit in the input of variable
speed drives causes current ripples that strain the DC-bus capacitors in the
inverter and generate harmonic distortions in the utility grid.
The power choke (50/60 Hz) flattens the charging current and reduces
harmonics - both are important factors for the reliability and lifetime of
the machine.
KEB COMBILINE power chokes flatten the output currents, reduce the strain on
the insulation and are available for output frequencies...50 Hz, ...100 Hz
and ...200 Hz.
|
|
Braking Resistors
The DC-bus capacitors of inverters can only partially
absorb regenerative energy and must be guided from the system to the
outside. KEB COMBIVERT are available with internal brake transistors (GTR7),
which transmit "excess" energy to external resistors.
The OHM-A and OHM-B resistors offer high pulse capacity at a small
installation space and
• feature thermal monitoring through break contacts (series feature)
• work without additional noise during braking
