1.5 Specified 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 Karl E. Brinkmann GmbH are developed and dimensioned 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 fulfilled, 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 coverage 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 (negative power), regeneration of the current into the mains occurs automatically. The regenerative level is defined 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 flow 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 flow between DC link and mains is blocked during regeneration. An appropriate error message 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 message E.nEt is displayed.
Special adjustments from KEB are necessary if the modulation and/or the standard operation should start again within a defined time in case of return of power supply.

Safety Instructions
2. Safety Instructions
2.1 General instructions
Danger Electric Shock
COMBIVERT R6 power supply and regenerative units contain dangerous voltages which can cause death or serious injury.
COMBIVERT R6 can be adjusted by way that energy is regenerated into the supply system in case of power failure at regenerative operation. Therefore a dangerous high tension can exist in the unit after switching off the supply system.
Before working with the unit check the isolation from supply by measurements in the unit.
Care should be taken to ensure correct and safe operation to minimise risk to personnel and equipment.
Warning Only Qualified Electro-Personnel
All work from the transport, to installation and start-up as well as maintenance may only be done by qualified personnel (IEC 364 and/or CENELEC
HD 384 and IEC-Report 664 and note national safety regulations). According to this manual qualified staff 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 field of power transmission.
Attention Observe standards
The COMBIVERT must not be started until it is determined that the installation complies with the Machine directive (2006/42/EC) as well as the EMC-directive (2004/108/EC)(note EN 60204).
The COMBIVERT meets the requirements of the Low-Voltage Directive
2006/95/EC. The harmonized standard of the series EN 61800-5-1 (VDE
0160) is used.
This is a product of limited availability in accordance with IEC 61800-3. This product may cause radio interference in residential areas. In this case, the operator must take appropriate measures.
11
Safety Instructions
2.2 Transport, storage and installation
The storage of the COMBIVERT must be done in the original packing. It is to be protected against humidity and excessive cooling and thermal effect. A long-distance transport must be carried out in the original packing. It is to be secured against impact influence. Observe the marking on the final packing! After removing the final packing the COMBIVERT must be shut down on a stable base.
Warning Protect Against Accidental Contact
The COMBIVERT R6 must be protected against invalid loading. Components and covers must not be bent or moved as this may affect insulation distances. The units contain electrostatic sensitive devices which can be destroyed by inappropriate handling. For that reason the contact of electronic devices and contacts is to be avoided. The equipment must not be switched on if it is damaged as it may no longer comply with mandatory standards.
Make sure that during installation there is enough minimum clearance and enough cooling.
Climatic conditions must be observed in accordance with the instruction manual.
Warning Hot surface
Heat sinks can reach temperatures, which can cause burns when touching. If in case of structural measures a direct contact cannot be avoided, a warning notice "hot surface" must be mounted at the machine.
2.3 Electrical connection
Danger Observe capacitor discharge time
Before any installation and connection work, the system must be switched off and secured.
After clearing the DC link capacitors are still charged with high voltage for a short period of time. The unit can be worked on again, after it has been switched off for 5 minutes.
Caution Safe isolation
The terminals of the control terminal strip are securely isolated in accordance with EN 61800-
5-1. With existing or newly wired circuits the person installing the units or machines must ensure that the EN requirements are met. With frequency inverters that are not isolated from the supply circuit all control lines must be included in other protective measures (e.g. double insulation or shielded, earthed and insulated).
12
Safety Instructions
Danger Voltage with respect to ground
The connection of COMBIVERT R6 is allowed to: a) symmetrical mains with a voltage phase (L1, L2, L3) with respect to neutral conductor/ ground (N/PE) of maximum 305 V.
b) phase conductor grounded supply networks:
• the control system is no longer regarded as “safe isolated circuit”, further protection measures are required therefore (see "Safe isolation").
• with this type of power system, the max. voltage phase / earth must not exceed 528 V absolute
• appropriate, external DC fuses at the DC connections are necessary for the 400 V class.
Use the COMBIVERT R6-N without internal DC fuses.
• Contact KEB regarding EMC filter.
Attention Fixed connection
The COMBIVERT R6 is designed for fixed connection, since discharge currents of > 3.5 mA occur especially when using together with EMI filters. Therefore, the requirements or instructions from EN 60204-1 (VDE 0113) and EN 61800-5-1 (IEC 0160-5-1) must be observed.
Caution Insulation measurement
When doing an insulation or voltage measurement in accordance with in EN 60204-1 /
VDE 0113-1, the power semiconductor of the unit and existing radio interference filters must be disconnected because of the danger of destruction. This is permissible in compliance with the standard, since all inverters are given a high voltage test in the end control at KEB.
In the case of special requirements please contact KEB.
Caution Different earth potentials
When using components without isolated inputs/outputs, it is necessary that equipotential bonding exists between the components to be connected (e.g. through the equalizer). Disregard can cause destruction of the components by the equalizing currents.
13
Safety Instructions
14
Caution Prevent malfunctions
A trouble-free and safe operation of the COMBIVERT R6 is only guaranteed when the connection instructions below are strictly followed. Incorrect operation or damage may result from incorrect installation:
• Pay attention to mains voltage.
• Install power cables and control cables separately (>15 cm separation).
• Use shielded / twisted control lines. Lay shield at one side to COMBIVERT R6-N to PE !
• Only use suitable circuit elements to control the logic and analog inputs, whose contacts are rated for extra-low voltages.
• Housing of the COMBIVERT R6 must be well earthed. Screens of larger power cable must be directly and securely attached to both the inverter PE terminal and the motor ground terminal (remove paint).
• Ground the cabinet or the system earth star point with the shortest connection to mains earth. (avoid earth loops)
• Use exclusively the line commutation throttle specified by KEB.
• The average value of the supplied DC current may not exceed the maximum DC current.
• If several frequency inverters are connected to the COMBIVERT R6-N the max. permissible DC link capacities of all connected frequency inverters must be considered during supply operation (see technical data).
Warning Automatic restart
The COMBIVERT R6 can be adjusted by such way that the inverter restarts automatically after an error case (e.g. broken phase line). System design must take this into account, if appropriate, and additional monitoring or protective features added where necessary.
Caution Not short-circuit proof (supply)
The COMBIVERT R6 is not short-circuit proof at the mains input ! Conditional protection at the mains input is possible if the I
2 t-protection was adapted with a gR fuse. The short-circuit protection at DC output is ensured by internal or external aR respectively gR fuses.
Caution Conditionally short-circuit proof (regeneration)
The COMBIVERT R6 is conditionally short-circuit proof (EN 61800-5-1 / VDE 0160). The intended function is guaranteed after resetting the internal protection devices.
Exception:
• If earth- or short circuits often occurs at the output, this can lead to a defect in the unit.
Safety Instructions
Attention Cyclic activation and deactivation
With applications requiring the COMBIVERT R6 to be switched on and off cyclically, maintain an off-time of at least 5 min. If you require shorter cycle times please contact KEB.
Switching off during the initialization phase can cause undefined conditions.
Attention RCD (residual current operated circuit-breaker)
When using systems with RCD, the instructions or the requirements of VDE 0100 -T 530
(IEC 60364-5) must be observed. The recommended tripping current of the RCD type „B“ is
300 mA.
15
EMC instructions
2.4 EMC instructions
COMBIVERT R6-N represent electrical equipment designed for use in industrial and commercial units. In accordance with the EMC directive 2006/108/EC, it is not obligatory to mark these devices as they represent components to be further processed by the respective machine and unit manufacturer and are not operable independently according to the EMC directive. The person installing / operating the machine / unit is obliged to prove the protective measures demanded by the EMC directive are complied with. The prescribed ratings can usually be complied with when using the radio interference voltage filters specified by KEB, and when observing the following measures and installation guidelines.
2.5 EMC conform installation
The COMBIVERT R6 is designed to be used in the second environment as defined in EN
61800-3 (unit with its own supply transformer). Take additional filter measures when using it in the first environment (residential and commercial area connected to public low-voltage mains)!
• Install the control cabinet or system in an appropriate and correctly way (see chapter „EMC conform control cabinet installation“)
• To avoid coupled-in noise, separate supply lines, motor lines, control and data lines (low-voltage level < 48 V) and leave a space of at least 15 cm between them when installing.
• In order to maintain low-resistance high frequency connections, earthing and shielding, as well as other metallic connections (e.g. mounting plate, installed units) must be in metal-to-metal contact with the mounting plate, over as large an area as possible. Make ground connections with a surface as large as possible (earthing strips).
• Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for high frequency ranges. The screen must always be installed on the compensating rail and fastened with clips or guided through the wall of the housing. Do not elongate the screen end (pigtails) with individual conductors!
• If external interference suppression filters are used, then these must be installed as close as possible to (<30 cm from) the interference source and in metal-to-metal contact with the mounting plate, over as large an area as possible.
• Always equip inductive control elements (contactors, relays etc.) with suppressors such as varistors, RC-elements or damping diodes.
• All connections must be kept as short as possible and as close as possible to the earth, as free floating lines work as active and passive aerials.
• Keep connection cables straight (do not bundle). Install a non-assigned wire at one sides to the protective earth conductor.
• The flow and return circuit must be twisted when the lines are not shielded, in order to dampen common-mode noise.
• Further information can be found in the internet, see „www.keb.de“.

Bracket values obtain for operation at 230 V power supply. The unit is automatically adjusted by the software when switching on.
The overload current is specified for 1 minute. The overload cycle is 300 seconds. This corresponds to duty class 2
EN 60146-1-1.
The current data are based on a fundamental frequency component of g=0.95. The fundamental frequency component or the effective value of the input current is dependent on load and line supply conditions. At uncontrolled
B6 converters the phase angle cosφ1 can be set to one, so the value of the fundamental frequency components is equal to the value of the power factor.
If the DC infeed current > 85 A DC use two by two of the DC terminals (++ and --) to meet the requirements of the
UL standard. The connection cables are parallel connected.
Please contact KEB for higher values.

Technical Data
Warning General instructions
•
•
•
Voltage stabilization must be activated at the frequency inverter if a harmonic filter is used.
•
The units are not short-circuit proof without corresponding dimensioned fuses.
•
Exceeding of the max. rechargeable DC link capacity can lead to a defect.
•
A load removal in the DC link circle may be done only after the message „ready“.
If the control release is set when switching off the mains, this can lead to an overcurrent error and the lifetime of the module can be reduced.
The unit must be disconnected from the supply system or the load must be switched off in case of overcurrent or overload.

3.7.6 Ferrite rings
Ferrite rings are used to reduce the cable-fed and radiated disturbances. For a high damping they are placed as close as possible to the interference source, that means at the DC and motor output terminals of the inverter. The conductor are passed through the ferrite core for the use as current-compensated reactor. PE is passed outside the core. Further information is specified in the provided documentation. The ferrite ring to be used arises from the used cable cross-section.

4.3.1 General description of inverter input terminals
Caution Starting current limiting
When connecting inverters to a DC bus pay attention to the internal wiring of the DC voltage inputs !
Inverters that directly output the DC link bus to the DC terminals must be integrated into the DC bus by way that the supply unit(s) limit the starting current. The precharging must be completed within two seconds.
Caution Maximum DC link capacity
The maximum DC link capacity can be calculated by adding the DC link capacities of all inverters in the DC bus. A table for this can be found in the appendix. The supply source
(supply unit or inverter with AC input) must be suitable for this value.

This type can be supplied by mains and by DC circuit.
The starting current limitation is designed after the input terminals. When used as output parallel connected inverters must have an own starting current limiting at the DC voltage input. The maximum charging current is taken into account.
This type can be supplied by mains. The DC terminals can be used as output with regard to the maximum DC link capacity. When used as input ensure that the starting current is externally limited.
Figure 12: General description of input terminals at KEB inverter
This type is only a DC inverter with starting current limiting. The DC inverter can be combined with all other types in consideration of the maximum DC link capacity.

4.3.2 Connection terminals of the R6-N power circuit
Info Input voltage
The COMBIVERT R6-N in E-housing is suitable for rated voltages of 230 V and 400 V. The regenerative unit checks the mains at the first switching on and adjusts the parameters accordingly (see parameter CP.31 if mains supply is changed).
Attention View of power supply and regenerative units
The terminals of a power supply and regenerative unit can be input or output dependent on the actual operating status (power supply or regeneration). For the standardization of the view the line side is always regarded as input and the DC voltage side is always regarded as output.

Operation of the Unit
5. Operation of the Unit
5.1 Operation with PC and system software COMBIVIS
Instructions for the installation and operation of the system software COMBIVIS can be taken from the appropriate software instruction.
5.2 Switch-on procedure
The COMBIVERT R6-N is initialized after connection of the power supply. The power circuit identification is checked first. If an invalid power circuit is recognized, error „E.Puci” (Power unit code invalid) is released and displayed in the operator. This error cannot be reset, the power circuit must be checked.
The COMBIVERT R6-N changes into synchronisation phase if a valid power circuit is recognized.The following procedures take place one after another during this synchronisation phase:
• Testing the input phases -> error „E.nEt” is triggered if a net phase is missing.
• Testing the phase allocation -> error „E.SYn” is triggered if a phase allocation error occurs
(reverse rotation).
The actual mains frequency is determined and the correct connection of the COMBIVERT
R6-N is secured after successful synchronisation. If the control release (terminal ST) is set, the COMBIVERT R6-N starts independently with the specified operation. Depending whether regenerative requirement is available, the COMBIVERT R6-N is in status „rEGEn” or „Stb”.
Status „Stb“
COMBIVERT R6-N detects a typical voltage level in the DC link circuit of the connected frequency inverter (motor operation) and keeps the modulation signals of the regenerative unit deactivated.
Status „rEGEn”
If the DC voltage in the DC link (CP.09 or ru.19) exceeds the value of the regeneration level
(CP.34 or cs.02) referring to the reference value ru.18, the modulation signals are activated and the unit changes into regenerative operation. Further the regenerative unit is switched active, if regenerative operation is requested by an additional installed COMBIVERT R6-N in the system (master /slave operation).

Frequently asked questions
The COMBIVERT R6-N is a power supply and regenerative unit that serves exclusively for the supply of frequency inverters with DC input and/or regeneration of excess energy into the supply system. It is not intended for other electrical consumers.
The COMBIVERT R6-N converts AC to DC, supplies KEB frequency inverters, regenerates excess energy, reduces energy demand and heat emission, and is protected against overcurrent, ground fault and temperature. It also has DC fuses for short-circuit protection.
The regenerative unit feeds back the excess energy from generatoric operation into the supply system. This reduces the energy demand and heat emission, makes it environmentally friendly and space-saving, replaces braking resistor and braking transistor, and is cost-saving.
Before working with the unit, always ensure the system is switched off and secured. The DC link capacitors may still be charged with high voltage after switching off the supply system. It is recommended to wait at least 5 minutes before working with the unit after it has been switched off. Always check the isolation from the supply by measurements in the unit.
