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 dimensio-
ned for the use in industrial products. If the KEB COMBIVERT is used in machi-
nes, 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 64 or CENELEC HD 84 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 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 011 (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.

.. Input signals channel 2
...1 Serial data transmission
Singleturn absolute encoder divide one revolution of the shaft into a de󰘰ned number of
measuring steps. This are 4096 positions at a SSI protocol, corresponding to a resolution
of 12 Bit. Multiturn absolute encoder do not only detect angle positions within one revolution
but also the number of revolutions. With a resolution of the multiturn part of 12 Bit this cor-

responds to 4096 revolutions. The position measuring area of 0…224-1 should not be left,
since an over󰘱ow and/or under󰘱ow is not evaluated as error. A system o󰘯set can be de󰘰ned
by writing on Ec.4 or approaching to reference point.

...2 Encoder breakage recognition
An error bit is evaluated for monitoring of the encoder at channel 2. The monitoring is swit-
ched on/o󰘯 with parameter Ec.42 (Ec.20 up to V2.8). The recognition of encoder breakage
triggers an „error! encoder 1“ (value 2).

..4 Connection of the encoder
• Encoder cable double-shielded and twisted in pairs
• Connect exterior shielding at both ends to PE/GND
• Connect interior shieldings at one side to COM
• Do not connect exterior and interior shielding
Two connection examples of SSI encoders are following. The assignment of the motor en-
coder interface is di󰘯erent according to the manufacturer. The examples must be adopted
accordingly.

00F4609-0xxx xxx m z.B. 00F4609-0040 corresponds to 40 m
For Kübler encoder:
00F4909-xPxx x,xx m z.B. 00F4909-0P60 corresponds to 0,60 m
00F4909-0xxx xxx m z.B. 00F4909-0040 corresponds to 40 m
KEB encoder cables are corresponding to the following speci󰘰cation:
Signal lines  x (2 x 0,14 mm²)
Supply lines 2 x 0,5 mm²
Particularities trailing capable, oil-resistant
Temperature range constant upto 80 °C

..6 Encoder line length
The maximum line length for the connection line is limited by the signal frequency, cable
capacity and the line resistance.

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.10 and control whether value „6: SSI“ is entered. The
displayed value has to be con󰘰rmed by „ENTER“ in any case.
• Select parameter Ec.11 and adjust the increments per revolution to 1024.
• Select parameter Ec.17 and adjust 4-fold evaluation (1024 inc x 4 = 4096 inc)
• Select Ec.42 (Ec.20 upto V2.8) and adjust the encoder breakage recognition
dependent on the case of operation.
• Select parameter Ec.21 and adjust multiturn resolution (standard 12 Bit); ad-
just „0“ for singleturn encoders.
• Select parameter Ec.22 and adjust clock frequency for SSI encoder.
• Select parameter Ec.2 and adjust data format (standard Gray-Code).
• Ec.0 displays the read out position of the SSI encoder.
• A system o󰘯set can be de󰘰ned by writing on parameter Ec.4 or approaching
to reference point.
