Preface
1. Preface
The described hard and software are developments of the KEB Automation KG. The en-
closed documents correspond to conditions valid at printing. Misprint, mistakes and technical
changes reserved.
1.1 Information on special measures
Theusedpictogramshavefollowingsignicance:
Danger Is used, when death or serious bodily injury may be the consequence
of non-observance of the measure.
Warning Is used, when bodily injury and/or substantial property damage may
be the consequence of non-observance of the measure.
Caution Is used, when property damage may be the consequence of non-ob-
servance of the measure.
Attention Is used, when noise sensitive or unrequested operation may be the
consequence of non-observance of the measure.
Info Is used, when a better or simpler result can be the consequence of the
measure.
For a special case the instructions can be supplemented by additional pictograms and text.

Preface
Step 3
The entire documentation associated with the device will be displayed, in-
cluding the instruction manuals in German and English. If available, other
translations are also indicated. Make sure that the user understands the pro-
vided language.
Should you be unable to read or understand the documentation, do not
take any further steps. Please inform our support network for further
assistance.
Non-observance of the safety and operating instructions leads to the loss of any liability
claims. The warnings and safety instructions in this manual work only supplementary. This
list is not exhaustive.
1.3 Validity and liability
The use of our units in the target products is beyond of our control and therefore exclu-
sively the responsibility of the machine manufacturer, system integrator or customer.
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 mod-
ied.
Danger by tamper from unauthorized personnel
Unauthorised opening and tampering may lead to death, bodily injury, prop-
ertydamageandmalfunctions.Modicationorrepairispermittedonlyby
KEB authorized personnel. Infringement will annul the liability for resulting
consequences.
Thesuspensionofliabilityisespeciallyvalidalsoforoperationinterruptionloss,lossofprot,
data loss or other damages. The disclaimer will void the warranty. This is also valid, if we
referredrsttothepossibilityofsuchdamages.
If single regulations should be or become void, invalid or impracticable, the effectivity of all
other regulations or agreements is not affected.
Through multitude applications not each possible case of installation, operation or mainte-
nance can be considered. If you require further information or if special problems arise which
are not treated in detail in the documentation, you can request the required information from
the local agency of the company KEB Automation KG.
1.4 Copyright
The customer may use the instruction manual as well as further documents or parts from it
for internal purposes. Copyrights are with KEB Automation KG and remain valid in its entirety.

1.5 Speciedapplication
The COMBIVERT R6-N serves exclusively for the supply of frequency inverters with DC input
and/or regeneration of excess energy into the supply system. The operation of other electrical
consumers is prohibited and can lead to malfunctions or to the destruction of the units.
The used semiconductors and components of the KEB Automation KG are developed and di-
mensioned for the use in industrial products. If the KEB COMBIVERT F5 is used in machines,
which work under exceptional conditions or if essential functions, life-supporting measures or
anextraordinarysafetystepmustbefullled,thenecessaryreliabilityandsecuritymustbe
ensured by the machine builder.
The operation of our products outside the indicated limit values of the technical data leads to
the loss of any liability claims.
All output functions of the R6 are "one-channel according to ISO 13849, no diagnostic cov-
erage and therefore not safe". If required, additional protective measures must be met by the
user.
1.5.1 Standard operation
If the DC link voltage increases to a value above the peak value of the mains voltage (nega-
tive power), regeneration of the current into the mains occurs automatically. The regenerative
levelisdenedwithparameterCP.34orcS.02.Themainsvoltageisanalogmeasured.The
regenerativecurrentisequaltothefeed-in,wherebythecurrentowperiodscorrespondto
the times of a B6 bridge circuit. Regeneration is completed if the regenerative and puls off
level (CP.32 or cS.06) is fallen below.

Preface
1.5.2 Abnormal operation
When exceeding the permissible limit values for voltage, current or temperature the current
owbetweenDClinkandmainsisblockedduringregeneration.Anappropriateerrormes-
sage is also displayed during supply. The unit must be disconnected from the supply system
or the load must be switched off in case of overcurrent or overload. This can be done by
opening the control release of the frequency inverter.
At factory setting the modulation is switched off in case of a net phase failure and error mes-
sage E.nEt is displayed.
Special adjustments from KEB are necessary if the modulation and/or the standard operation
shouldstartagainwithinadenedtimeincaseofreturnofpowersupply.
1.6 Product description
This instruction manual describes the power supply and regenerative unit KEB COMBIVERT
R6-N. The COMBIVERT R6-N has the following features.
The supply unit
• converts a three-phase input voltage into DC voltage.
• supplies single KEB frequency inverter or via DC interconnection.
• can be parallel connected while maintaining a base load if higher power supply is required.
• increases the stability of the DC link voltage in the DC interconnection.
The regenerative unit
• feeds back the excess energy from generatoric operation into the supply system.
• reduces the energy demand.
• reduces the heat emission.
• is environmentally friendly and space-saving.
• replaces braking resistor and braking transistor.
• is cost-saving.
• hasthesamecurrentow(harmoniccomponents)suchasfeed-inandrarelynoise
level
The COMBIVERT R6-N is generally protected against overcurrent, ground fault and tempera-
ture. Appropriate dimensioned DC fuses protects the DC link circuit against short-circuit. The
following accessories are necessary for operation with the COMBIVERT R6-N:
• Mains choke
• EMClterE6(forobservanceofEMCstandard)respectivelyvoltagelimitation
