Tip
Non-observanceofthesafetyinstructionsleadstothelossofanyliabilityclaims.Thislistis
not exhaustive.
1.2 Validity and liability
The use of our units in the target products is outside of our control and therefore lies
exclusively in the area of responsibility of the machine manufacturer.
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 responsibil-
ity.Thisalsoappliestoanyviolationofindustrialpropertyrightsofathird-party.
Selection of our units in view of their suitability for the intended use must be done generally
by the user.
Testscanonlybedonewithintheapplicationbythemachinemanufacturer.Theymustbe
repeated,evenifonlypartsofhardware,softwareortheunitadjustmentaremodied.
Unauthorised opening and tampering may lead to bodily injury and property damage and
may entail the loss of warranty rights. Original spare parts and authorized accessories by the
manufacturerserveassecurity.Theuseofotherpartsexcludesliabilityfortheconsequences
arising out of.

2.2.2 HSP5 interface X4A
TheHSP5interfaceX4Aservesforthecommunicationwithacontroloperator.Adigitalop-
erator,interfaceoperatoranddifferenteldbusoperatorsareavailableforthis.Toprevent
malfunctions, the inverter must be brought into nOP status before connecting / disconnecting
theoperator(opencontrolreleaseterminal).Whenstartingtheinverter,itisstartedalways
with the last stored values or factory setting.
AspecialHSP5cable(partnumber00.F5.0C0-0010)isrequiredfortheoperationoftheKEB
COMBIVERTwithoutoperator.ThiscableisconnectedbetweenHSP5interfaceX4Aand
serialRS232PCinterface(COM1orCOM2).OperationoccursviatheprogramCOMBIVIS.
TheHSP5servicecablehasanintegratedlevelconverter.Theconnectionofaserial
standard cable would destroy the PC interface.
2.2.3 Encoder interfaces X3A, X3B
TheCOMBIVERTF5canbeequippedoptionallywithencoderinterfaces.Differentcombina-
tionscanbeusedhereaccordingtotherequirements.Theinstructionismadeseparately

2.3 Connection of the control
Thefollowinginstructionsmustbeobservedatconnection:
Attention Prevent EMC malfunctions
•Use shielded / drilled cables
•Lay shield on one side of the inverter onto earth potential
• Installcontrolcablesandpowercablesseparately(approx.10…20cm
distance);KreuzungenimrechtenWinkelverlegen
• Toavoidinterferencesaseparateshieldingmustbeprovidedforanalog
and digital control lines. Depending on the use of the relay outputs, an ex-
tra shielding is to be used, too.
•In case of inductive load on the relay outputs a protective wiring must be
provided(e.g.free-wheelingdiode)!
Theterminalsofthecontrolterminalstripandthetransmitterinputsarese-
curelyisolatedinaccordancewithEN50178.

•Press pusher by hand. Insert connecting wires into the respective hole, that no single wires can
be seen from the outside or bend outward.
Arstresistancemustbeovercomewheninserting.Releasethepusher.
• Checkthattheconnectingwireisxedandcannotbepulled-out.Itisimportanttoensurethat
theconnectingwireandnottheinsulationisclamped.Theconnectingwirecanalsobeinserted
without pressing the pusher in case of cross-sections upto 1.00 mm².
Attention A safe clamping can not be guaranteed when using shorter wire-end

In order to ensure permanent security, the function must be
checked in regular intervals according to the results of the risk
analysis.
Installation work or troubleshooting can be necessary in hazard areas, whereby protective
devicessuchasline-ormotorcontactorsshallnotbeactivated.ThesafetyfunctionSTOcan
be used there. Depending on the application the use of line or motor contactors can be void
byusingSTO.
Incaseoferrororrequest,thepowersemiconductorofthedrivemoduleareswitchedoffand
thedriveisnotsupplied,whichcausesarotationortorque(incaseofalineardrivemove-
mentorforce).Theunitcanbesafeswitchedoffand/orremainifanerroroccurs.

functionenablesasimpleintegrationofdrivestofunctionalgroupsofasystem.Therebysafe
torqueoffcanbelimitedtocertainsystems.Afurtheradvantageisthattherechargeanddis-
chargetimeoftheinverterDClinkmustnotbeconsidered.Thustheunitisfasteragainready

Characteristicdatafor„Safetorqueoff“
• Powersupplyfortherotationdirectionofthemotorisinterrupted(free-wheelingmotor)
•Used when monitoring of standstill is not necessary
•Unintentional starting of the motor is prevented
•No galvanic isolation of the motor from the dc link circuit
WhatisrealizedbytheSTOfunctionrelatedtoEN60204-1?
• EmergencystopcanberealizedbytheSTOfunction,sincethemainsvoltagemayre-
main effective.
•Emergency stop can be realized only in connection with a line contactor, which discon-
nects the mains voltage !
3.1 Emergency stop according EN 60204
By using suitable safety switchgear units, stop category 0 and 1 according to EN 60204 -1
canbereachedbytheSTOfunctioninthesystem.Notechapter3.6forsafetyswitchgear
units.
Stop category 0 „uncontrolled stop“, i.e. stop by immediate removal of power to the
actuators.
Stop category 1
„controlled stop“, i.e. power to the actuators is retained to apply
brakinguntilthestopisachieved.Theenergyisswitchedoffat
standstill.
Emergency stop to EN 60204 must be functional in all operating modes of the drive module.
Theresetofemergencystopmaynotleadtoanuncontrolledstartofthedrive.
Restart only
afterconr-
mation
ThedriverestartsiffunctionSTOisnolongerreleased.Inorder
to comply with EN 60204, it must be ensured by external meas-
uresthatthedriverestartsonlyafterconrmation.
Withoutmechanicalbrakethedriveleadstocoast;motorisfree-wheeling.Additionalprotec-
tivedevicesmustbeinstalled(e.g.lockingsystems)ifdamagetopersonsorpropertycan
occur.
Ensure coast
of the motor
If danger to persons occur after switching off the motor control
bySTO,theentrancetohazardareasmustremaincloseduntil
the drive stops.
Jerks in error
case
In case of double malfunction it can lead to unwanted jerk, the
rotation angle is depending on the number of poles of the se-
lected drive and the gear ratio.

3.4 Additional instructions
• Theunitmustbeisolatedfrommainsbymainswitchwhenworkingonpartsundervolt-
age.
• Mechanical brakes must be installed additionally if external forces have effect to the drive
axis,e.g.verticalaxes(hangingloads)orrotaryaxeswithasymmetricalweightdistribu-
tion.
• Fortheprotectionagainstpollution(pollutiondegree2)theinstallationoftheunitsmust
beprovidedinenvironmentwithincreasedprotection(e.g.controlcabinetIP54).
• MakesurethatnosmallpartsfallintotheCOMBIVERTduringassemblyandwiring.This
also applies to mechanical components, which can lose small parts during operation.
• Check the safety functions and error responses and generate an acceptance report after
installation.
• The start-up can be prevented with interruption of the STO signals. STO may not be
released in case of danger according to EN 60204-1. Also note the instructions to the
external safety switch devices.
• Dimension the safety application by way that the corresponding input current of the safety
functionsisavailablefortheinputs(seechapter2.5.1).
Selection of
suitable volt-
age sources
Use for the connection only suitable voltage sources with safe

3.5 Functional Description
TheCOMBIVERTwithintegratedsafetyfunctionmeetsthefollowingfunctionaccordingto
IEC61800-5-2:
• „Safetorqueoff"(STO)
Thesafety-relateddisconnectionaccordingtoSTOisreachedbyatwo-cannelopto-coupler
blockage.Thesupplyoftheopto-couplers,whichareresponsibleforthecommutationofthe
connecteddriveoccursviatransformationcouplingoftheinputvoltage.Thisensuresatinput
voltage loss that no supply of the opto-couplers is possible. If the opto-couplers are not longer
supplied,noIGBTcanbecontrolledandthusnoenergycanbesuppliedtothedrive.
ThetwochannelsarereachedbywaythatinputSTO1preventsthevoltagesupply(VTRO)
oftheupperopto-couplersof theinverterbridgeandinputSTO2thelower opto-couplers
(VTRU).
