    The invention relates to a storage and retrieval unit for a rack storage system, which comprises a chassis, at least one drive motor which is coupled to one or more drive wheels of the storage and retrieval unit, power electronics which are connected to the at least one drive motor, and control electronics which are connected to the power electronics connected is. Furthermore, the invention relates to a shelf storage system which comprises a first shelf storage and a second shelf storage oriented parallel thereto with a shelf aisle therebetween, and a shelf operating device of the aforementioned type which can be moved in the shelf aisle and which can be moved into a transfer position in which a goods transfer or General cargo transfer between the storage and retrieval unit and the first and / or second shelf storage is made possible.
    Storage and retrieval machines and rack storage systems of the type mentioned are known in principle from the prior art, for example from AT 508 172 A1. Shelf storage systems are used to store piece goods or goods of all kinds, for example in a mail order company. The storage and retrieval unit as such is used for the storage and removal of the piece goods or goods into and from the rack storage.
    A disadvantage of known rack storage systems is the sometimes poor accessibility, which is due to the compactness of such a rack storage system. Often the shelf aisles are so narrow that it is not possible or only very difficult to pass through the shelf operating device to get to the other side in the shelf aisle. In addition, the compact design of a storage and retrieval machine and the weight of the piece goods or objects manipulated with it can lead to considerable losses
    2/34
    N2016 / 20200 AT-00
    Loads on the structure of the storage and retrieval machine, especially in the area of the chassis and the carrying wheels.
    It is therefore an object of the invention to provide an improved storage and retrieval unit and an improved shelf storage system. In particular, the accessibility to the installations and superstructures of a shelf operating device and also the access to a shelf aisle are to be improved. In addition, the storage and retrieval unit should be constructed in such a way that it can better cope with the loads that occur and, in particular, that it can also be more fragile and therefore more easily constructed. This is accompanied by higher possible accelerations and speeds with the same drive power.
    The object of the invention is achieved with a storage and retrieval unit of the type mentioned at the outset, in which the power electronics are installed in a first control cabinet and the control electronics in a second control cabinet, and both control cabinets are arranged spatially separated from one another on the storage and retrieval unit. This means that the first control cabinet is arranged in a first position and the second control cabinet in a second position.
    The object of the invention is also achieved with a shelf storage system of the type mentioned in the introduction, in which the first switch cabinet is arranged asymmetrically with respect to a center line running in the rack aisle and the first switch cabinet with a first minimum distance from the first rack and with a second Minimum distance to the second shelf is arranged, wherein the second minimum distance is greater than the first minimum distance and is at least 35 cm.
    In particular is
    a) the minimum distance between the first shelf and the first control cabinet is a maximum of 5 cm and the minimum distance between the second shelf and the first control cabinet is at least 35 cm if the width of the shelf aisle is in a range up to and including 105 cm, or
    b) the minimum distance between the first shelf and the first
    3/34
    N2016 / 20200 AT-00
    Control cabinet is a maximum of 15 cm and the minimum distance between the second shelf and the first control cabinet is at least 45 cm if the width of the shelf aisle is in a range of more than 105 cm up to and including 125 cm, or
    c) the minimum distance between the first shelf and the first control cabinet is a maximum of 23 cm and the minimum distance between the second shelf and the first control cabinet is at least 53 cm if the width of the shelf aisle is in a range of more than 125 cm up to and including 145 cm, or
    d) the minimum distance between the first shelf and the first control cabinet is a maximum of 30 cm and the minimum distance between the second shelf and the first control cabinet is at least 60 cm if the width of the shelf aisle is in a range above 145 cm.
    As an alternative to the relationship between the minimum distance between the first shelf and the first control cabinet, the minimum distance between the second shelf and the first control cabinet and the width of the shelf aisle, the following functional relationship is proposed:
    bimin ^ 5cm + (bs-IOOcm) · 0.50 b2min> 35cm + (bs-IOOcm) · 0.50 where bimin indicates the minimum distance between the first shelf and the first control cabinet, b2min the minimum distance between the second shelf and the first control cabinet and bs the Width of the shelf aisle.
    The proposed measures help to make the installations and superstructures of a storage and retrieval machine (e.g. a load handler) and the shelf aisle itself more accessible. This can be done on the one hand by dividing the power electronics and the control electronics into two smaller control cabinets, and on the other hand by the asymmetrical arrangement of at least the first control cabinet. By dividing the power electronics and the control electronics into two smaller control cabinets, the weight distribution of the
    4/34
    N2016 / 20200 AT-00
    Storage and retrieval machine improved. The storage and retrieval machine is therefore better able to cope with the stresses that occur during operation, or can be more fragile and therefore more easily constructed. This is accompanied by higher possible accelerations and speeds with the same drive power.
    In addition, the measures taken can reduce the EMC load (electromagnetic compatibility) of the control electronics, since the power electronics are arranged at a different location on the storage and retrieval unit. The provision of separate (metal) control cabinets also contributes to the mentioned reduction in EMC pollution.
    In the context of the invention, the power electronics connected to the traction motor in particular have a maximum, first power consumption of at least 50 kW. Furthermore, the control electronics connected to the power electronics in particular have a maximum, second power consumption of less than 2 kW. The specified values occur during operation of the storage and retrieval machine. In operation within the scope of the invention also means when the rack operating device is moving. In particular, the specified values for the maximum, first power consumption when accelerating the storage and retrieval machine are achieved. Of course, other load conditions also occur during operation. For example, less power is consumed during constant travel, or the power consumption can also turn negative if the storage and retrieval unit is braked recuperatively.
    The maximum, second power consumption can also include a power requirement for auxiliary units or (smaller) engines. The connection can be made directly to the second control cabinet or to the first control cabinet, provided that a corresponding cable is laid from the first to the second control cabinet. In particular, the power requirement which is assigned to the power electronics is a maximum of 200 W. This means that the electrical power required for controlling the power electronics is in particular a maximum of 200 W.

    Advantageous refinements and developments of the invention now emerge from the subclaims and from the description in conjunction with the figures.
    It is advantageous if the second control cabinet is arranged closer to the at least one traction motor than the first control cabinet. Since the control electronics are generally significantly lighter than the power electronics and the drive motor or the drive motors is / are comparatively heavy, the proposed arrangement leads to an advantageous weight distribution on the storage and retrieval unit. This is particularly true if the second control cabinet is located closer to all traction motors than the first control cabinet.
    It is also favorable if the storage and retrieval unit has a load suspension device that can be moved vertically on a mast. As a result, piece goods or goods can also be stored on a higher shelf and removed from it. Of course, the storage and retrieval unit can also have a plurality of masts, each with a load suspension device, a plurality of masts with a common load suspension device, or also masts with a plurality of load suspension devices.
    In this context, it is advantageous if the mast is arranged between the first control cabinet and the second control cabinet, based on the longitudinal direction of the storage and retrieval unit. The proposed arrangement also leads to an advantageous weight distribution on the storage and retrieval unit. This is particularly true when the mast is closer to the first cabinet than to the second cabinet. Another advantage of the arrangement mentioned is the comparatively low EMC load on the control electronics arranged in the second control cabinet. In this embodiment, the second control cabinet is relatively far away from a lifting motor for the load suspension device and also relatively far away from a control cabinet possibly mounted on the load suspension device.
    In a further embodiment variant of the storage and retrieval unit to achieve an advantageous weight distribution, the load suspension device is on a longitudinal
    6/34
    N2016 / 20200-AT-00 direction of the storage and retrieval machine, located between the first control cabinet and the second control cabinet.
    With regard to the weight distribution, it is also advantageous to arrange at least one first support wheel at one end of the undercarriage and at least one second support wheel at the other end of the undercarriage, and to arrange the first control cabinet above the at least first support wheel and the second control cabinet above the at least second support wheel to assemble.
    Finally, with regard to the weight distribution, it is also advantageous if the at least one traction motor, based on a longitudinal direction of the storage and retrieval unit, is arranged outside an intermediate space between the at least one first support wheel and the at least one second support wheel.
    In a rack storage system, it is also advantageous if a height of an upper edge of the first control cabinet and / or a height of an upper edge of the second control cabinet is less than 2.20 m above a floor of the rack aisle. This means that the built-in components in the control cabinets (e.g. electrical components and the like) are easily accessible without additional aids. This considerably simplifies the construction and maintenance of such a storage and retrieval unit. In particular, the built-in components in the control cabinet (e.g. switchgear and the like) are no higher than 2.00 m above the floor of the shelf aisle. In addition, the lower structure also simplifies the transport of a storage and retrieval machine, for example in a truck. The chassis of the storage and retrieval unit can generally be completely preassembled and transported upright by the proposed measures. The advantages mentioned are achieved in particular by dividing the power electronics and the control electronics into two different control cabinets.
    It is also advantageous if a switchgear cabinet door of the first switchgear cabinet is aligned transversely to the center line of the shelf aisle in the closed state, in particular normally. This improves access to the first control cabinet, which generally remains comparatively voluminous even after the power electronics and control electronics have been divided, in particular to a certain extent
    7/34
    N2016 / 20200-AT-00 len shelf aisles. With pivoting control cabinet doors, a pivot axis runs particularly vertically, i.e. normal to the center line of the shelf aisle and parallel to a mast. As an alternative or in addition, the control cabinet door can also be removable.
    It is also particularly advantageous if a ladder for ascending to the storage and retrieval unit is arranged on the control cabinet door. This also makes it easier to ascend to a storage and retrieval machine if, for example, maintenance work in the shelf storage system (e.g. in the storage warehouse or on the storage and retrieval machine) is required.
    It is also advantageous if a conveyor system is arranged at a first end of the rack aisle and is coupled to the rack storage system and the control cabinet door points to the first end of the rack aisle. This ensures good access to the first control cabinet. The shelf aisles often form dead ends that are only accessible from their first end.
    Another advantage of arranging the first control cabinet at that end of the rack operating device which faces the first end of the rack aisle is the advantageous use of the available space. The conveyor technology generally has buffer conveyors on which conveyed objects or piece goods can be temporarily stored before they are transferred to a collecting conveyor or to the storage and retrieval unit. Therefore, at the first end of the shelf aisle, space becomes free in its extension, which is taken up by the relatively voluminous first control cabinet as a result of the proposed measures.
    In a particularly advantageous embodiment, the rack storage system comprises a controller which is designed to automatically move a load-handling device of the rack operating device to a height of at least 2 m above a floor of the rack aisle if an entry of a person to the rack aisle in which the said storage and retrieval machine moves. For safety reasons, people must not be in the rack aisle in which the storage and retrieval machine moves while the storage and retrieval machine is in operation. Corresponding Si
    8/34
    N2016 / 20200-AT-00 security areas can be secured, for example, with light barriers, doors and the like. The storage and retrieval machine is stopped when an entry or access request by the person is detected. In addition, the measures proposed above can be taken. Raising the load handler to a height of at least 2 m above the floor makes it easier to pass through the rack operating device and to access the aisle section of the rack aisle located behind the rack operating device.
    At this point it should be noted that the division of the power electronics and the control electronics into two different control cabinets and the asymmetrical arrangement of at least the first control cabinet in the shelf aisle are two measures that can be taken independently of one another, particularly effectively but in combination are. In principle, the measures proposed in claims 11 to 15 can be used independently of the measures proposed in claims 1 to 10. However, the features disclosed in claims 1 to 10 can also be advantageous in a rack storage system according to claims 11 to 15.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    To begin with, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally, etc. related to the figure described and illustrated immediately and in the case of a change of position to be transferred accordingly to the new position.
    All information on value ranges in the present description should be understood to include any and all sub-areas, e.g. the information 1 to 10 is to be understood in such a way that all sub-areas starting from the lower limit 1 and the upper limit 10 are also included, i.e. all sub-areas start with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7 or 3.2 to 8.1 or 5.5 to 10.
    Figures 1 to 6 show a shelf storage system 1a, comprising a first shelf storage 2a and a parallel aligned second shelf storage 2b with an intermediate shelf aisle 3 and a shelf operating device 4a which can be moved in the shelf aisle 3 and which can be moved into a transfer position in which a goods - Or bulk goods transfer between the storage and retrieval unit 4a and the first and / or second shelf storage 2a, 2b is made possible. 1 and 5 show a side view of the rack storage system 1a mentioned, in FIGS. 2 and 6 a top view, in FIG. 3 a view A from the left and in FIG. 4 a view B from the right.
    10/34
    N2016 / 20200 AT-00
    The storage and retrieval machine 4a comprises a chassis 5 with a plurality of carrying wheels 6a, 6b and at least one travel motor 7, which is coupled to a drive wheel 8 or a plurality of driving wheels of the storage and retrieval machine 4a. The carrying wheels 6a, 6b run on a rail 9 which is mounted on a floor 10 (e.g. a warehouse). The rail 9 is arranged along a center line C between the two shelves 2a, 2b. But it could also be mounted elsewhere.
    In addition, the storage and retrieval unit 4a has a first control cabinet 11 and a second control cabinet 12. The two control cabinets 11 and 12 are arranged spatially separated from one another on the storage and retrieval unit 4a. That is, the first control cabinet 11 is arranged in a first position and the second control cabinet 12 in a second position. Specifically, the first control cabinet 11 and the second control cabinet 12 are mounted on the chassis 5 in this example.
    Power electronics are installed in the first control cabinet 11 and are electrically connected to the at least one traction motor 7. Control electronics, which are electrically connected to said power electronics, are installed in second control cabinet 12. A cable, not shown in the figures, is therefore laid between the first control cabinet 11 and the second control cabinet 12. In operation, the power electronics have in particular a maximum, first power consumption of at least 50 kW and the control electronics in particular a maximum, second power consumption of less than 2 kW (see also FIG. 10).
    In addition, the storage and retrieval unit 4a has a load-carrying means 14 which can be moved vertically on a mast 13 and with which piece goods can be stored in or removed from the rack 2a, 2b.
    The shelves 2a, 2b finally each have a plurality of shelf supports 15, on which shelves 16 are mounted. The storage and retrieval unit 4a can move horizontally in the rack aisle 3 with the help of the drive motors 7 in a manner known per se. The load suspension device 14 can also be moved vertically in a manner known per se. In this way, the storage and retrieval unit 4a can be moved into a transfer position in which a goods or general cargo transfer between
    11/34
    N2016 / 20200-AT-00 the storage and retrieval unit 4a and the first and / or second shelf storage 2a, 2b is made possible with the aid of the load suspension means 14.
    In the example shown, the second control cabinet 12 is arranged closer to the at least one traction motor 7 than the first control cabinet 11. The second control cabinet 12 is even arranged closer to all the traction motors 7 than the first control cabinet 11.
    In addition, the mast 13 is arranged between the first control cabinet 11 and the second control cabinet 12 with respect to the longitudinal direction of the storage and retrieval unit 4a. Specifically, the mast 13 is closer to the first switchgear cabinet 11 than to the second switchgear cabinet 12. The load suspension means 14 is arranged between the first switchgear cabinet 11 and the second switchgear cabinet 12, based on a longitudinal direction of the storage and retrieval unit 4a.
    A first carrying wheel 6a is arranged at one end of the undercarriage 5 and a second wheel 6a at the other end of the undercarriage 5. The first switchgear cabinet 11 is mounted above the first wheel 6a and the second switchgear cabinet 12 above the second wheel 6b. The two traction motors 7 are arranged outside of an intermediate space between the first carrying wheel 6a and the second carrying wheel 6b, based on a longitudinal direction of the storage and retrieval unit 4a.
    The positions of the structural units 5, 6a, 6b, 7, 11, 12, 13 and 14 of the storage and retrieval unit 4a proposed above lead individually and all the more to an advantageous weight distribution on the storage and retrieval unit 4a. Of course, the storage and retrieval unit 4a can also be constructed differently than suggested.
    For example, types are known which move on two rails mounted on the floor and types which are mounted on two rails arranged vertically one above the other. The carrying wheels can also be driven directly and separately provided drive wheels can be omitted. Depending on the load, more than two carrying wheels can also be provided. The rack storage can also be constructed differently than shown. For example, shelves can be omitted and
    12/34
    N2016 / 20200-AT-00 instead supports should be provided on which the piece goods are placed. The measures proposed above can of course be used independently of a special type of rack storage system.
    In a real shelf storage system 1a, the weight of the first control cabinet 11 is approximately 200 kg, the weight of the second control cabinet 12 is approximately 80 kg and the weight of the traction motors 7 is approximately 250 kg. This results in a relatively uniform load on the carrying wheels 6a, 6b. This is further supported by the fact that the traction motors 7 are arranged outside a space between the first support wheel 6a and the second support wheel 6b, and the mast 13 is also closer to the first control cabinet 11.
    The upper edge of the first control cabinet 11 and / or second control cabinet 12 is advantageously not higher than 2.20 m above the floor 10. In FIG. 5, for better understanding, the height hi of the upper edge of the first control cabinet 11 is above the floor 10 and the height h2 of the upper edge of the second control cabinet 12 is shown above the floor 10. In this way, the internals (e.g. electrical components) in the control cabinets 11 and 12 are easily accessible even without a climbing aid. Fall protection can also be omitted. In principle, the specified maximum height for the first control cabinet 11 and / or second control cabinet 12 is also expedient if the division of the power electronics and the control electronics defined above and in claim 1 is not present.
    The first control cabinet 11 is advantageously arranged asymmetrically with respect to the center line C running in the shelf aisle 3, as is shown in FIG. 6. 6 additionally shows the distance bi of the first control cabinet 11 to the first shelf 2a, the distance b2 of the first control cabinet 11 to the second shelf 2b, the distance b3 of the second control cabinet 12 to the first shelf 2a and the distance b4 of the second control cabinet 12 to the second shelf 2b and the width bs of shelf aisle 3 entered.
    The following conditions exist in an exemplary, real shelf storage system 1a: the width bs of shelf aisle 3 is 100 cm, the width of the
    13/34
    N2016 / 20200-AT-00 first control cabinet 11 is 60 cm, the distance bi is 5 cm, and the distance b2 is 35 cm. Despite the relatively narrow shelf aisle 3, one person can pass through the storage and retrieval device 4a and reach the section of the shelf aisle 3 behind it. This is achieved on the one hand by dividing the power electronics and the control electronics between the two control cabinets 11 and 12 and thus making the first control cabinet 11 narrower, and on the other hand by arranging the first control cabinet 11 asymmetrically in the shelf aisle 3. Depending on the width of the rack aisle 3 and the width of the first control cabinet 11, only one of the two measures may be sufficient. The measures taken for the first control cabinet 11 can of course also be provided for the second control cabinet 12. The distance b4 is therefore advantageously at least 35 cm.
    Generally it is an advantage if
    a) the minimum distance bi between the first shelf 2a and the first control cabinet 11 is a maximum of 5 cm and the minimum distance b2 between the second shelf 2b and the first control cabinet 11 is at least 35 cm if a width bs of the shelf aisle 3 is in a range up to and including 105 cm, or
    b) the minimum distance bi between the first shelf 2a and the first control cabinet 11 is a maximum of 15 cm and the minimum distance b2 between the second shelf 2b and the first control cabinet 11 is at least 45 cm if a width bs of the shelf aisle 3 is in a range of more than 105 cm to 125 cm inclusive, or
    c) the minimum distance bi between the first shelf 2a and the first control cabinet 11 is a maximum of 23 cm and the minimum distance b2 between the second shelf 2b and the first control cabinet 11 is at least 53 cm if a width bs of the shelf aisle 3 is in a range of more than 125 cm to 145 cm inclusive, or
    d) the minimum distance bi between the first shelf 2a and the first control cabinet 11 is a maximum of 30 cm and the minimum distance b2 between the second shelf 2b and the first control cabinet 11 is at least 60 cm if a width bs of the shelf aisle 3 is in a range above 145 cm lies
    14/34
    N2016 / 20200 AT-00
    Alternatively, the following functional relationship is suggested:
    bimin ^ 5cm + (b5-100cm) · 0.50 b2min> 35cm + (b5-100cm) · 0.50 where bimin indicates the minimum distance between the first shelf 2a and the first control cabinet 11, b2min the minimum distance between the second shelf 2b and the first control cabinet 11 and bs the width of the shelf aisle 3.
    In particular, it is also advantageous if a control of the rack storage system 1 a is designed to automatically move the load-carrying means 14 of the rack operating device 4 a to a height h 3 of at least 2 m above the floor 10 if an entry of a person into the rack aisle 3 is detected , in which said storage and retrieval machine 4a travels (see also FIG. 9).
    7 now shows a somewhat more detailed illustration of a storage and retrieval unit 4a. In particular, a lifting motor 17 together with flanged gear 18 are also shown. Furthermore, FIG. 7 shows lower side guide wheels 19a, which bear laterally on the rail 9, and upper side guide wheels 19b, which run in a guide rail 20 mounted on the shelf 2a, 2b. In this example, the load suspension means 14 is formed by a schematically illustrated telescopic fork. The load suspension device 14 can in particular be movable on both sides, so that both shelves 2a and 2b can be operated.
    In general, it is advantageous if a switchgear cabinet door 21 of the first switchgear cabinet 11 is aligned in the closed state transversely to the center line C running in the shelf aisle 3, in particular normally, as is the case in FIG. 8. Specifically, the control cabinet door 21 is pivotable about an axis D and can be opened with a handle 22. 8, the axis D is oriented perpendicular or normal to the center line C and parallel to the mast 13. In principle, however, the axis D could also be oriented horizontally, so that the control cabinet door 21 swings up or down. As an alternative or in addition, the control cabinet door 21 can also be removable.
    15/34
    N2016 / 20200 AT-00
    FIG. 8 also shows a ladder 23 mounted on the control cabinet door 21, with which an ascent to the storage and retrieval unit 4a is possible. The ascent can also be continued via a ladder 24 which is mounted on the mast 13.
    9 shows a shelf storage system 1c with three shelves 2a., 2c and two shelf operating devices 4a, 4b in conjunction with a conveyor technology which is arranged at a first end of the shelf aisles 3 and is coupled to the shelf storage system 1c. Specifically, the conveyor technology in this example comprises three buffer conveyors 25a..25c, which are coupled to a collecting conveyor 26. With the aid of this conveyor technology, piece goods can be transported in a manner known per se to the rack storage system 1c or away from it. The control cabinet doors 21a, 21b advantageously point to the first end of the rack aisles, to which the conveyor technology is coupled. This ensures good accessibility to the first control cabinet 11. The shelf aisles often form 3 dead ends, which are only accessible from their first end.
    Another feature of the arrangement of the first control cabinet 11 on that end of the storage and retrieval device 4a, 4b that faces the first end of the rack aisle 3 is an advantageous use of the available space. Piece goods can be temporarily stored on the buffer conveyors 25a..25c before they are transferred to the collecting conveyor 26 or to the storage and retrieval unit 4a, 4b. The space freed up by the buffer conveyors 25a..25c at the first end of the rack aisle 3 is taken up by the relatively voluminous first control cabinet 11 by the proposed measures.
    9 also shows security areas 27a and 27b in which people are not allowed to stay during the operation of the storage and retrieval machines 4a and 4b. The security areas 27a and 27b can be secured in a manner known per se with light barriers, doors and the like, the storage and retrieval devices 4a and 4b being stopped upon detection of an entry or access request by a person.

    For example, at the left end of a shelf aisle 3 there is an operating door through which the shelf aisle 3 can be entered for maintenance work and the like, and at the right end an escape door through which the shelf aisle 3 can be exited in an emergency.
    In addition, it can advantageously be provided that the load-carrying device 14 of a rack operating device 4a, 4b is automatically moved to a height h3 of at least 2m above the floor 10 if an entry of a person into the rack aisle 3 or to the security area 27a, 27b is detected (see see also Fig. 5). This makes it easier to pass through the storage and retrieval machine 4a, 4b.
    10 finally shows a simplified, electrical circuit diagram of the storage and retrieval unit 4a, 4b. Specifically, the circuit diagram shows the motor 7, power electronics 28 connected to it (which is installed in the first control cabinet 11) and control electronics 29 connected to the power electronics 28 (which is installed in the second control cabinet 12). The power electronics 28 and the control electronics 29 are connected to a voltage source U.
    The control electronics 29 receives control commands Zi from a central control (not shown) in a manner known per se, implements these control commands Zi and in turn sends control commands Z2 to the power electronics 28. The power electronics 28 then controls the motor 7. The control commands Zi and Z2 can each be transmitted wirelessly or by wire.
    A maximum, first power consumption Pi of the power electronics 28 is in particular at least 50 kW in the examples shown in the figures. A maximum, second power consumption P2 of the control electronics 29 is in particular less than 2 kW in the examples shown in the figures.
    10, the power electronics 28 and the control electronics 29 are connected to the same voltage. Of course, this is not a necessary condition for the invention. Of course, the power electronics 28 and the control electronics 29 can also be connected to different voltages. Bei17 / 34
    N2016 / 20200-AT-00 for example, the power electronics 28 can be connected to a voltage of 400 V and the control electronics 29 to a voltage of 24 V. Of course, a voltage converter can also be installed in the second control cabinet 12, which, for example, generates a voltage of 24 V from a voltage of 400 V.
    Finally, it is stated that the scope of protection is determined by the claims. However, the description and drawings are to be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The object on which the independent inventive solutions are based can be found in the description.
    In particular, it is also stated that the devices shown can in reality also comprise more or fewer components than shown. In some cases, the devices shown or their components can also be shown to scale and / or enlarged and / or reduced.
