This manual describes the KEB COMBIVERT B6. Particular attention is paid to the in-
stallation, the connection as well as the basic operation. Due to the various application
and programming possibilities, the application-specic connection and/or wiring diagram,
the parameter adjustment as well as instructions to the start-up are to be taken from the
documentation of the machine manufacturer.
A list of instruction manuals and documents giving assistance for the construction, docu-
mentation and service is provided at the end of this manual. The safety and warning notes
listed in this instruction manual as well as in other documentation must be observed at
any rate to ensure a safe operation. The safety and warning instructions specied in this
manual do not lay claim on completeness. The KEB Automation KG reserves the right to
change/adapt specications and technical data without prior notice. The used pictograms
have following signicance:

Tip
The information contained in the technical documentation, as well as any user-specic advice
in spoken and written and through tests, are made to best of our knowledge and information
about the application. However, they are considered for information only without responsibi-
lity. This also applies to any violation of industrial property rights of a third-party.
Inspection of our units in view of their suitability for the intended use must be done generally
by the user. Inspections are particulary necessary, if changes are executed, which serve
for the further development or adaption of our products to the applications (hardware,
software or download lists). Inspections must be repeated completely, even if only parts
of hardware, software or download lists are modied. Original spare parts and authorized
accessories by the manufacturer serve as security. The use of other parts excludes liability
for the damages which can result from it.
Application and use of our units in the target products is outside of our control and
therefore lies exclusively in the area of responsibility of the user.
Unauthorised opening and tampering may lead to bodily injury and property damage and
may entail the loss of warranty rights.

1. General
In operation, drive converters, depending on their degree of
protection, may have live, uninsulated, and possibly also moving
or rotating parts, as well as hot surfaces.
In case of inadmissible removal of the required covers, of improper
use, wrong installation or maloperation, there is the danger of
serious personal injury and damage to property.
For further information, see documentation.
All operations serving transport, installation and commissioning
as well as maintenance are to be carried out by skilled technical
personnel (Observe IEC 364 or CENELEC HD 384 or DIN VDE
0100 and IEC 664 or DIN/VDE 0110 and national accident
prevention rules!).
For the purposes of these basic safety instructions, „skilled
technical personnel“ means persons who are familiar with the
installation, mounting, commissioning and operation of the
product and have the qualications needed for the performance
of their functions.
2. Intended use
Drive converters are components designed for inclusion in elec-
trical installations or machinery.
In case of installation in machinery, commissioning of the drive
converter (i.e. the starting of normal operation) is prohibited until
the machinery has been proved to conform to the provisions of
the directive 2006/42/EC (Machinery Safety Directive - MSD).
Account is to be taken of EN 60204.
Commissioning (i.e. the starting of normal operation) is admissible
only where conformity with the EMC directive (2004/108/EC) has
been established.
The drive converters meet the requirements of the Low-Voltage
directive 2006/95/EC. They are subject to the harmonized stan-
dards of the series DIN EN 50178/VDE 0160 in conjunction with EN
60439-1/ VDE 0660, part 500, and EN 60146/ VDE 0558.
The technical data as well as information concerning the supply
conditions shall be taken from the rating plate and from the docu-
mentation and shall be strictly observed.
3. Transport, storage
The instructions for transport, storage and proper use shall be
complied with.
The climatic conditions shall be in conformity with EN 50178.
4 Installation
The installation and cooling of the appliances shall be in accor-
dance with the specications in the pertinent documentation.
The drive converters shall be protected against excessive strains.
In particular, no components must be bent or isolating distances
altered in the course of transportation or handling. No contact shall
be made with electronic components and contacts.
Drive converters contain electrostatic sensitive components
which are liable to damage through improper use. Electric
components must not be mechanically damaged or destroyed
(potential health risks).
5. Electrical connection
When working on live drive converters, the applicable national
accident prevention rules (e.g. VBG 4) must be complied with.
The electrical installation shall be carried out in accordance
with the relevant requirements (e.g. cross-sectional areas of
conductors, fusing, PE connection). For further information, see
documentation.
Instructions for the installation in accordance with EMC require-
ments, like screening, earthing, location of lters and wiring, are
contained in the drive converter documentation. They must always
be complied with, also for drive converters bearing a CE marking.
Observance of the limit values required by EMC law is the respon-
sibility of the manufacturer of the installation or machine.
6. Operation
Installations which include drive converters shall be equipped
with additional control and protective devices in accordance with
the relevant applicable safety requirements, e.g. act respecting
technical equipment, accident prevention rules etc.. Changes
to the drive converters by means of the operating software are
admissible.
After disconnection of the drive converter from the voltage supply,
live appliance parts and power terminals must not be touched
immediately because of possibly energized capacitors. In this
respect, the corresponding signs and markings on the drive
converter must be respected.
During operation, all covers and doors shall be kept closed.
7. Maintenance and servicing
The manufacturer’s documentation shall be followed.

The at-rear design (projected) requires cooling measures by the
machine builder. This can be in the best case no further measure at
all (e.g. at cyclic operation with down times) up to the dissipation of
the entire, indicated heat loss at rated operation.
The COMBIVERT must be protected against aggressive
gases, aerosols and conductive dust !
3.2 EMC conform Installation
• Always apply the shielding of motor
and control cables over a large contact
surface on both sides.
• Distance between control and power
cables at least 10…20 cm (4…8 inch).
• Lay motor and power cable separately.
• If it cannot be avoided, cross control
and power cables in a right angle.
• Install all cables as close as possible
to the mounting plate - ideal in a metal
cable duct.
• Mount COMBIVERT well conducting
with the mounting plate. Remove the
paint beforehand.
You can nd further instructions regarding
the EMC- conform wiring in the Internet

3.3.6 Note to the function
In the example above the locking of the line contactor K1 is interrupted in case of overhe-
ating of the braking resistor. The line contactor drops and switches off the mains voltage.
The auxiliary contacts 13/14 open the error linkage circuit at terminals I1/COM (T1/T2) and
release an error. The modulation is switched off. Thus the drive in generatoric operation
does not regenerate further energy into the DC link circuit.
Depending on the case of application (e.g. no generatoric operation) simple
circuits can be used. See chapter 7 for instructions of the download. Input I1
must be programmed and inverted in the application mode to "external error".

4.2.1 Parameter numbers and values
When switching on KEB COMBIVERT B6 the value of parameter CP.1 appears.
The function key changes between the parameter
value and parameter number.
With UP (▲) and DOWN (▼) the parameter number
or at changeable parameters the value is increased/
decreased.
Principally during a change, parameter values are immediately accepted and stored non-
volatile. However, with some parameters it is not useful that the adjusted value is accepted
immediately. In these cases the adjusted value is accepted and stored non-volatile by
pressing ENTER. When this type of parameter is changed a point appears behind the
last digit.
By pressing „ENTER“ the adjusted value is
accepted and non-volatile stored.
4.2.2 Resetting error messages
If a malfunction occurs during operation, the actual display is overwritten by the error
message. The error message in the display is reset by ENTER.
