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
Theinformationcontainedinthetechnicaldocumentation,aswellasanyuser-specicadviceinspokenand
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-
peatedcompletely,evenifonlypartsofhardware,softwareordownloadlistsaremodied.
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-
portingmeasuresoranextraordinarysafetystepmustbefullled,thenecessary
reliability and security must be ensured by the machine builder.
1.2 Qualication
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
accidentpreventionrules!).Accordingtothismanualqualiedstaffmeansthosewhoareabletorecognise
and judge the possible dangers based on their technical training and experience and those with knowledge of
therelevantstandardsandwhoarefamiliarwiththeeldofpowertransmission(VDE0100,VDE0160(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
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.

3.1.3 Input signals channel 1
3.1.3.1 Signal tracks
A sine-wave voltage is output at terminals REF_HI and REF_LO at the resolver interface.
Thisvoltagesuppliestheeldwindingintheresolver.Thissignalistransmittedviaarotary

eldsignal.Howevertheiramplitudesaredependingonthepositionoftherotorwinding.
The induced voltage has maximum value if rotor and measuring winding are parallel. No
voltage is induced in signal winding in right angle to each other. Both signal voltages are
directly transferred to the encoder interface.

3.1.3.2 Encoder breakage recognition channel 1
Input signals SIN_HI and COS_HI are monitored for the monitoring of the resolver at chan-
nel 1. The monitoring for channel 1 will be switched on/off with parameter Ec.42 (in the past
Ec.20).
The recognition of encoder breakage triggers an „error! encoder 1"(value 32), if the voltage
atsignalinputsSIN_HIandCOS_HIisoutsideofthespecication.

3.1.7 Tested encoders
The following resolvers have been tested by KEB on it application:
• Tamagawa TS2620N21E11(default)
• Tamagawa TS2641N11E64
• LTN RE-15-1-A14
• LTN RE-21-1-A05
• Harowe 10BRCX401k1C
However,thisdoesnotrestricttheuseofrotaryencoderwithsamespecicationsofother
manufacturers.
3.2 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 „19: resolver interface“ is entered.
Thedisplayedvaluehastobeconrmedby„ENTER“inanycase.
•Select Ec.42 and adjust the encoder breakage recognition dependent on the case of
operation.
The resolver evaluation block generates incremental signals, which can be
output via encoder simulation (channel 2 = TTL output). The number of the
generated pulses is indicated in Ec.01. Parameter Ec.07 is without function.
Exception: control card application

GB-10
4.1 Special resolver
The use of 2-pole resolvers (pole-pair number 1) is provided as standard. If a resolver with
another pole-pair number shall be used, the pole-pair number is to be used as gear factor.
Gear factor denominator
= pole-pair number–––––––––––––––––––––
Gear factor numerator
If synchronous motors shall be operated in this constellation, it must be guaranteed that the
value pole-pair number x gear factor is integer (see example).
Example:
6-pole resolver (3 pole-pairs) at channel 1,
pole-pair number of the synchronous motor = 3
Ec.05 Gear factor channel 1 denomi-
nator
3000
= pole-pair number––––––––––––––––––––––––––––––
–––
= ––––
––
Ec.04 Gear factor channel 1 numerator 1000
The operation of encoders which are not directly mounted at the motor or for operation of
resolvers with a pole-pair number > 1, parameter Ec.39 must be set to „1: motor encoder“.
The gear factor is 1/3, the pole-pair number of the motor = 3
Gear factor x pole-pair number of the motor = 1
=> Synchronous motor can be operated in this constellation.
5. Error Messages
Error messages and their meaning are described in the inverter documentation.
For safety reasons a power-on-reset must always be executed after error
„E.EnC“.
