Safety Instructions
1. Safety Instructions
Prior to performing any work on the unit the user must familiarize himself with the unit. This includes especially
the knowledge and observance of the safety and warning directions. The pictographs used in this instruction
manual have following meaning:
Danger Refers to danger of life by electric current.
Warning Refers to possible danger of injury or life.
Note Refers to tips and additional information.
1.1 Validity
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 responsibility. 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 particularly 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 re-
peated completely, even if only parts of hardware, software or download lists are modied.
Controlling by
the user
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.
Use under spe-
cial conditions
The used semiconductors and components of KEB are developed and dimensi-
oned for the use in industrial products. If the KEB COMBIVERT is used in ma-
chines, which work under exceptional conditions or if essential functions, life-sup-
porting measures or an extraordinary safety step must be fullled, the necessary
reliability and security must be ensured by the machine builder.
1.2 Qualication
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 national
accident prevention rules!). According to this manual qualied staff means those who are able to recognise
and judge the possible dangers based on their technical training and experience and those with knowledge
of the relevant standards and who are familiar with the eld of power transmission (VDE 0100, VDE 0160
(EN 50178), VDE 0113 (EN 60204) as well as the appropriate regulations for your area.
Danger by high
voltage
KEB electronics components contain dangerous voltages which can cause death
or serious injury. In operation, drive converters, depending on their degree of
protection, may have live, uninsulated, and possibly also moving and 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.

2.1 General
Each of the interface cards delivered by KEB include two interfaces. As there are numerous
different combinations available each interface will be described by means of separate
instructions. The instruction covers the installation of the interface card, the connection as
well as the start-up of a suitable encoder. Further information and the parameter adjust-
ments are described in the application manual for the inverter/servo.

3.2.4.2 Evaluation of the Zero Signal
The zero impulse is required to determine valid position points. In case of pure speed con-
trols the signal does not need to be connected. In the following signal sequence the maxi-
mum permissible length of the zero impulse of the encoder is visible. The zero signal will
be acquired if A+ ,B+ and N+ are at high level. By that there is only one valid position point
which is independent from the travel direction.

3.2.5 Encoder breakage recognition
For a monitoring of the encoder and the encoder cable the signal tracks and the zero track
are monitored. Input N+ must be connected with input 15/24 V if the connected encoder
shouldnothaveazerotrack.Themonitoringforchannel1willbeswitchedon/o󰘯withpa-
rameter Ec.42 (in the past Ec.20). The recognition of encoder breakage triggers an „error"!
encoder 1“ (value 32), if the voltage at the signal input is smaller than 6 V.
Parameter r/w Enter prog.
Ec.42 Encoder alarm mode yes no no
Dependent on Ec.42 „Error! Encoder 1“ (value 32) or a warning is triggered, if the permis-
sible signal levels are fallen below.

supply line. The value is calculated as follows:
Encoder cable length = U - Umin

3.2.9 Tested encoders
The following encoder can be used dependent on the interface and the control:
Manufacturer Type Encoder type
Heidenhain • ROD 436 HTL-Incremental Encoder
However, this does not restrict the use of rotary encoder with same specications of other
manufacturers.
3.3 Channel 2
The description of input X3B is depending on the used encoder interface. It is described in
a separate manual.
4. Start-up
After the installation or exchange of an encoder interface some adjustments of the inverter/
servo software have to be done before operation:
•Switch on inverter
•Select application mode
•Select parameter Ec.00 and control whether value „27: Inc. encoder input HTL termi-
nal block with alarm“ is entered. The displayed value has to be conrmed by „ENTER“
in any case.
•Select Ec.01 and adjust increments per revolution.
•Select Ec.42 (Ec.20 upto V2.8) and adjust the encoder breakage recognition depen-
dent on the case of operation.
5. Error Messages
Error messages and their meaning are described in the application manual.
Error „E.hYb“ can be reset by a Power-On-Reset. Error „E.EncC“ can by writing
on parameter ec.00 and additional also be reset by a Hardware-Reset or Bus-
Reset (control word) since software version 4.1.
