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 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 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 sta󰘯 means:
- those who are able to recognise and judge the possible dangers based on their technical training and experience
-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 approporiate 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
di󰘯erent 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.

3.3.3.2 Evaluation of the Zero Signal
The zero impulse is required to determine valid position points. In case of pure speed
controls the signal does not need to be connected. In the following signal sequence the
maximum permissible length of the zero impulse of the encoder is visible. The zero signal is
acquired when A+ ,B+ and N+ are on high level. Thus there is only one valid position value
independent of the travel direction.

3.2.3.3 Encoder breakage recognition
For a monitoring of the encoder to channel 1 and the encoder cable the signal tracks and
the zero track are monitored. If the connected encoder has no zero track, then the the 5 V-
supply must be assigned to track N+ and COM to N- at the encoder plug. The monitoring
forchannel1willbeswitchedon/o󰘯withparameterEc.42(inthepastEc.20).
The recognition of encoder breakage triggers an „error! encoder 1“ (value 32), if the voltage
between two signal pairs is smaller than 625mV.

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parameterEc.0andcontrolwhethervalue„13incrementalencoderinput24VTTL
In“isentered.Thedisplayedvaluehastobecon󰘰rmedby„ENTER“inanycase.
•SelectEc.1andadjustincrementsperrevolution
•SelectEc.42(Ec.20uptoV2.8)andadjusttheencoderbreakagerecognitiondependent
