Introduction

1.5 Specified application

The COMBIVERT R6-S 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 KEB are developed and dimensioned for the use in industrial products. If the product 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 build er. 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 (nega tive power), regeneration of the current into the mains occurs automatically. The regenera tive level is defined with parameter CP.34 or cS.02. The mains voltage is analog measured.

Regeneration is carried out in square-wave, whereby the current flow period is corresponding 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.

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 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 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

Electric shock

COMBIVERT R6 power supply und 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 be 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.

Only qualified electropersonnel

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.

Standards discharge time

The COMBIVERT R6 must not be started until it is determined that the installation complies with 2006/42/EC (machine directive) (note EN60204).

The COMBIVERT R6 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 may need to take corresponding measures.

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.

GB - 9

Safety Instructions

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.

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

Note 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.

Secure 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).

Voltage with respect to ground

The connection of COMBIVERT R6 is allowed to: symmetrical mains with a voltage phase (L1, L2, L3) with respect to neutral conductor/ ground (N/PE) of maximum 305 V.

Stationary connection

The COMBIVERT R6 is designed for fixed connection, since discharge cur rents of > 3.5 mA occur especially when using together with EMC filters. There fore, the requirements or instructions from EN 60204-1 (VDE 0113) and EN

61800-5-1 (IEC 0160-5-1) must be observed.

GB - 10

Safety Instructions

Insulation measurement

When doing an insulation or voltage measurement in accordance with 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.

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.

GB - 11

Safety Instructions

Prevent disturbances

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-S 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 COMVIBERT R6-S the max. permissible DC link capacities of all connected frequency inverters must be considered during supply operation (see technical data).

Automatic restart

The COMBIVERT R6 can be adjusted by such way that the inverter restarts automatically after an error case (e.g. phase failure). System design must take this into account, if appropriate, and additional monitoring or protective features added where necessary.

Not shortcircuit proof

(supply)

The COMBIVERT R6 is not short-circuit proof at the power supply input ! A con ditional protection at the supply input is possible if the I 2 t-protection is adapted with a gR fuse. Short-circuit protection at the DC output is ensured by internal or external aR or gR fuses.

GB - 12

Safety Instructions

Conditionally shortcircuit 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.

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.

RCD (residual current operated circuitbreaker)

When using systems with RCD, the instructions or the requirements of VDE

0100 -T 530 (IEC 60364-5) must be observed. The recommended tripping cur rent of RCD type "B" is 300 mA.

GB - 13

EMC instructions

2.4 EMC instructions

COMBIVERT R6-S represent electrical equipment designed for use in industrial and commercial units.

In accordance with the EMC directive 2014/30/EU, these devices are with the meaning of the directive components to be further processed by the respective machine and unit manufacturer and are not operable independently.

The person installing / operating the machine / unit is obliged to proove 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 noises, separate supply lines, DC lines, motor lines, control and data lines (low-voltage level < 48V) 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 metalto-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 mouting 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.

• The cable for phase synchronization between mains choke and COMBIVERT R6-S may not exceed a cable length of 1 m.

• Further information can be found in the internet, see „www.keb.de“.

The overload current is specified for 1 minute. The overload cycle is 300 seconds. This corresponds to load class 2 according to EN 60146-01-1.

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.

Please contact KEB for higher values.

Technical Data

Voltage stabilization must be activated at the 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.

3.4.1 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

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 ten seconds.

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. In consideration of the DC link capacity the

DC voltage terminals can be used as output. When used as input ensure that the starting current is externally limited.

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.

Operation of the Unit

5. Operation of the Unit

5.1 Operation with PC und 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-S is initialized after connection of the power supply. The power circuit identification is checked first. If an invalid power unit 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-S changes into synchronisation phase if a valid power circuit is recognized. The following procedures happens one after another during this synchronisation phase:

• Inspection of correct synchronisation connection (error "E.nEt" is released, if the synchro nous signal is missing)

• Inspection of the phase allocation of synchronous signals to the mains phases. Error

"E.SYn" is released if a phase is missing or in case of phase allocation failure.

The actual line frequency and the mains voltage is determined after successful synchronisation. The correct connection of the COMBIVERT R6-S is now ensured. If the control release

(terminal ST) is set, the COMBIVERT R6-S starts independently with the normal operation.

Depending whether regenerative requirement is available, the COMBIVERT R6-S is in status

„rEGEn” or „Stb”.

Status „Stb“

COMBIVERT R6-S 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 ac tivated and the unit changes into regenerative operation. Furthermore the regenerative unit is switched active, if regenerative operation is requested by an additional installed COMBI-

VERT R6-S in the system (master /slave operation).
