| Cooling concepts
electronics - The Modular Cooling Concept |
| The frequency
inverter and servo drive KEB COMBIVERT offer a modular heat sink concept to
adapt to mechanical and thermal conditions in different applications. |
|
|
|
 |
|
 |
| Convection Heat Sink |
| This is the compact standard design including
additional ventilation. The drive is designed in IP 20 and is mounted inside
the panel. | |
|
| Push Through Heat Sink |
| This heat sink concept reduces heat in the panel by up
to 80%. This means smaller cabinets can be used. With the thermal separation
of the heatsink and the installation of the drives in the enclosure the heat
remains outside. That results in better ambient conditions for the
electronic components and thus improves reliability. | |
|
|
 |
|
 |
| Flat Rear Heat Sink |
| This cooling concept utilizes the thermal capacity of
the machine itself or master heat sink to dissipate the heat. | |
|
| 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 - KEB COMBIVERT Power Supply and Regenerative Systems |
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. |
|
|
|
 |
|
 |
| KEB COMBIVERT R6 Power Supply and Regenerative System |
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.
Saves energy through regeneration...friendly for the environment! | |
|
| KEB COMBIVERT R5 Power Supply Unit |
The connection of electrical drives makes it possible
to internally balance kinetic energy.
KEB COMBIVERT R5 is a centralized supply module for DC-bus coupled frequency
inverters and servo drives. The integrated braking transistor and the
central DC fuse reduce the complexity of the system installation.
The centrally supplied machine has a smaller power consumption and a higher
resistance in case of line-voltage drops. | |
|
|
| Communication - KEB
COMBICOM Serial Networking |
We connect drives

Modularity is achieved with pluggable field bus operators. The whole family of
KEB COMBIVERT drives can be connected to all commonly used serial fieldbus
systems.

| Profibus, CAN, Sercos, InterBus, DeviceNet, Modbus |
Established Fieldbus Connections...
are 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 fieldbus standards for the
entire range of inverters and servo systems. | |
|
| Ethernet, Ethercat, Powerlink, Profinet |
Ethernet-based solutions…
use the worldwide expansion of the IT network technology for industrial
applications.
Ethernet TCP/IP connects the actuator level cost effectively to the IT
level. This results in an easy start-up and diagnostics.
Ethernet and Powerlink provide real-time features to the drives so they can
be used for high dynamic applications and motion control.
Profinet RT and Profinet IRT are further solutions which KEB will integrate
in 2007. Sercos III and Ethernet IP will also be realized in 2007. | |
|
|
| EMC Technique |
EMC is an
important factor for the operational reliability in machinery and plants and
ensured the compliance with valid norms and standards. European norms and
standards require manufacturers and users to comply with a set of EMC
limitations.
KEB designs, manufactures and supplies a comprehensive range of input/output
filters and chokes to comply with all international standards as well as to
improve operating conditions. KEB experts in the field of EMC offer advice and
support during the selection process of suitable products. For on-site testing a
mobile EMC service is available. Competent consultation and mobile EMC-measuring
means provide the options and optimisation on location - in short - they save in
different uses the dependable compliance of the monetary requirements. |

 |
| KEB COMBILINE HF Filter |
Variable speed drives with uncontrolled rectifier
input can cause low or high frequency interferences on the line that are
limited by the EMC regulations.
Adherance to the standards are ensured with the use of a universal EMC
filter. The EMC filters can be used to work with a single drive or as
central filters used for several components in one system.
KEB COMBILINE EMC filters are designed for industrial or residential areas
and can be supplied up to 1,000 A rated current.
Product offering: 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. | |
|
| |
KEB COMBILINE Harmonic Filter
Achieving sinusoidal harmonic current from standard 6 pulse rectifier load
has always been a challenge. Historically this could only be accomplished
through the use of costly components and more complicated rectification
schemes.
The KEB COMBILINE harmonic filter is an innovative solution for equipping
machines or retrofitting production systems. The compact design of the
filter (patent pending) is available in two types:
- 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. | |

- analysis of communication between drive and control
KEB COMBIVIS can be run on all PC's with serial interface and the
operating system Windows 95, 98, NT and 2000, XP. | |
|
| KEB COMBILINE 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 mains choke (50/60 Hz) flatten the charging current and reduce
harmonics. Both are important factors for the reliability and lifetime of
the machine.
The modulated output voltage of the inverter stresses the isolation. This
can result in problems in applications with long motor leads.
KEB COMBILINE motor chokes flatten the output currents, reduce the strain on
the isolation and are available for the output frequencies...50 Hz, ...100
Hz and ...200 Hz. | |

| KEB COMBIPERM Permanent Magnet Brakes and Clutches |
KEB COMBIPERM are clutches and brakes that operate
according to the following principles: in currentless state a frictionally
engaged connection of shafts is created through permanent magnet brakes.

neutralized by the counteracting magnetic field of the coil.
Rare earth magnet materials guarantee a high temperature resistance (ISO
class F) and a wide operating temperature range (20 - 100° C) for safe
operation.
