たとえば複数のモータを制御する多軸用モータ制御装置においては、例えば図６のように、個別に単独用の制御基板３４〜３７を搭載した４台のインバータユニット３０〜３３を、電線２６を用いて通信回路で接続し、上位制御回路２４で運転する場合がある。
また、図７のように、頻繁に使用する４台のインバータユニット３０〜３３を、それぞれ制御基板３４〜３７に接続して、１台に集約したユニットとして多軸モータ制御装置３８を製作し、内部配線として通信回路を電線２６で接続し、上位制御回路２４で運転する場合がある。また図７の内部配線を省略する為、図８のように、４台分の制御基板を１つにまとめた４台用専用制御基板３９を製作するとともに、各インバータユニット３０〜３３間の通信回路をパターンで接続して多軸用モータ制御装置４０を製作し、電線２６を介して上位制御回路２４に接続して運転する場合がある（例えば、特許文献１参照）。 For example, in a multi-axis motor control apparatus that controls a plurality of motors, for example, as shown in FIG. 6, four inverter units 30 to 33 each equipped with a single control board 34 to 37 are used as electric wires 26. May be connected by a communication circuit and operated by the host control circuit 24.
In addition, as shown in FIG. 7, four inverter units 30 to 33 that are frequently used are connected to control boards 34 to 37, respectively, and a multi-axis motor control device 38 is manufactured as a single unit. As an internal wiring, a communication circuit may be connected by an electric wire 26 and operated by the host control circuit 24. Further, in order to omit the internal wiring in FIG. 7, as shown in FIG. 8, a dedicated control board 39 for four units, in which four control boards are combined into one, is manufactured, and communication between the inverter units 30 to 33 is performed. The multi-axis motor control device 40 may be manufactured by connecting the circuits in a pattern, and may be operated by being connected to the host control circuit 24 via the electric wire 26 (see, for example, Patent Document 1).

以下、本発明の実施の形態について、図を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の第１の実施例における多軸用モータ制御装置の下半部を示す側断面図である。図２は、図１における多軸用モータ制御装置の集合用制御基板の正面図である。
本第１の実施例では、制御基板を集合用制御基板のまま使用する例を示している。
図１および図２において、１は多軸用、たとえば４軸用のモータ制御装置、２は前記多軸用モータ制御装置１の筐体、３は前記筐体２に取り付けられた基板支持体、４は前記基板支持体３に取り付けられた集合用制御基板、５は前記前記筐体２に取り付けられたヒートシンクでベース部５ａにフィン５ｂを備えている。６〜９は前記ヒートシンク５のベース部５ａ上に配置されたたとえば４個のインバータユニットである。
前記集合用制御基板４は、図２に示すように、インバータユニット６〜９の個数と同じ個数である４個の制御基板１０〜１３を、同一基板上に配置し、スリット１４で容易に分割できる構造となっている。さらに制御基板１０〜１３間の通信回路がパターン１５で接続され、そのパターン１５には、それぞれの制御基板１０〜１３内において、それぞれ２つのパッドからなるゼロオーム抵抗用パッド１６〜１９の一方のパッドが接続されるとともに、ゼロオーム抵抗が実装されている。２０〜２３は前記ゼロオーム抵抗用パッド１６〜１９と接続されるパターン１５が通る連結部である。また、制御基板１０のみ上位制御回路２４と接続するためのコネクタ２５が実装されている。２６は前記集合用制御基板４と前記上位制御回路２４とを接続する電線である。
多軸用モータ制御装置の製造においては、４個の制御基板１０〜１３を一箇所に配置することが可能な場合は、前記集合用制御基板４をそのままの状態で、前記基板支持体３上に配置することが、組立が簡単で望ましい。 FIG. 1 is a side sectional view showing a lower half of a multi-axis motor control device according to a first embodiment of the present invention. FIG. 2 is a front view of the collective control board of the multi-axis motor control device in FIG.
In the first embodiment, an example is shown in which the control board is used as it is as a collective control board.
In FIG. 1 and FIG. 2, 1 is a multi-axis motor control device, for example, a 4-axis motor control device, 2 is a housing of the multi-axis motor control device 1, 3 is a substrate support attached to the housing 2, Reference numeral 4 denotes a collective control board attached to the substrate support 3, and 5 denotes a heat sink attached to the housing 2, and includes fins 5 b in the base portion 5 a. Reference numerals 6 to 9 denote, for example, four inverter units arranged on the base portion 5 a of the heat sink 5.
As shown in FIG. 2, the collective control board 4 has four control boards 10 to 13 which are the same as the number of inverter units 6 to 9 arranged on the same board and easily divided by the slits 14. It has a structure that can be done. Further, a communication circuit between the control boards 10 to 13 is connected by a pattern 15, and in the control board 10 to 13, one pad of zero ohm resistance pads 16 to 19 each made up of two pads. Are connected and a zero ohm resistor is mounted. Reference numerals 20 to 23 denote connecting portions through which the patterns 15 connected to the zero ohm resistance pads 16 to 19 pass. In addition, a connector 25 for connecting only the control board 10 to the upper control circuit 24 is mounted. An electric wire 26 connects the collective control board 4 and the host control circuit 24.
In the manufacture of the multi-axis motor control device, when the four control boards 10 to 13 can be arranged at one place, the assembly control board 4 is left as it is on the board support 3. It is desirable that it is easy to assemble.

４個の制御基板１０〜１３を一箇所にまとめて配置することができない場合は、前記集合用制御基板４から制御基板１０〜１３を切り離して単独用制御基板として用い、それぞれの制御基板１０〜１３を適切な個所に配置することができる。
図３は、本発明の第２の実施例を示すもので、図２における集合用制御基板から切り離して用いる単独用制御基板の正面図である。
前記集合用制御基板４内の制御基板１０〜１３を、単独用制御基板として使用する際は、図３に示すように、前記ゼロオーム抵抗用パッド１６〜１９へのゼロオーム抵抗を未実装にするとともに、集合用制御基板４にて未実装であったコネクタ２７，２８を全て実装し、かつ、前記集合用制御基板４のスリット１４の連結部（つなぎ目）をカットして切り離すようにする。
前記集合用制御基板４のスリット１４の連結部をカットすると、切り離された制御基板１０〜１３は、パターン１５が切断されて、その切断面の銅箔が剥き出しになる。銅箔が剥き出しになったパターンは、時間とともに腐食が進行するが、前記ゼロオーム抵抗用パッド１６〜１９へのゼロオーム抵抗を未実装にしているので、腐食は、ゼロオーム抵抗用パッド１６〜１９の一方のパッドまででとどめることができる。
また、前記コネクタ２７，２８で、電線接続が可能となるので、切断されたパターン１５の代わりを、コネクタ２７，２８にて電線接続が可能となる。 When the four control boards 10 to 13 cannot be arranged in one place, the control boards 10 to 13 are separated from the collective control board 4 and used as single control boards. 13 can be placed at an appropriate location.
FIG. 3 shows a second embodiment of the present invention and is a front view of a single control board used separately from the collective control board in FIG.
When the control boards 10 to 13 in the collective control board 4 are used as single control boards, as shown in FIG. 3, the zero ohm resistors to the zero ohm resistor pads 16 to 19 are not mounted. The connectors 27 and 28 not mounted on the assembly control board 4 are all mounted, and the connecting portion (joint) of the slits 14 of the assembly control board 4 is cut and separated.
When the connecting portion of the slits 14 of the collective control board 4 is cut, the pattern 15 is cut in the separated control boards 10 to 13, and the copper foil on the cut surface is exposed. The pattern in which the copper foil is exposed is subject to corrosion over time. However, since the zero ohm resistance to the zero ohm resistance pads 16 to 19 is not mounted, the corrosion is one of the zero ohm resistance pads 16 to 19. It can be stopped with up to the pad.
Further, since the connectors 27 and 28 enable electric wire connection, the electric wires can be connected by the connectors 27 and 28 instead of the cut pattern 15.

図４は、本発明の第３の実施例における集合用制御基板を示す正面図である。図５は、図４における集合用制御基板から切り離して用いる単独用制御基板の正面図である。
第１の実施例においては、前記それぞれの単独用の制御基板１０Ａ〜１３Ａ内に前記パターン１５が引き込まれて、前記ゼロオーム抵抗用パッド１６〜１９と接続されるようにしていたが、この第３の実施例では、集合用制御基板４Ａは、前記それぞれの単独用制御基板１０Ａ〜１３Ａの連結部２０〜２３を跨いだ個所に、ゼロオーム抵抗用パッド１６〜１９のそれぞれのパッドを配置し、前記それぞれの単独用制御基板１０Ａ〜１３Ａ外で、前記ゼロオーム抵抗用パッド１６〜１９と前記パターン１５を接続するようにしている。
この場合、集合制御用基板４Ａの複数の連結部を切り離して単独用制御基板として使用する際に、パターン１５を切断することがない。したがって、集合制御用基板４Ａから切り離された単独用制御基板１０Ａ〜１３Ａには、パターン腐食の問題が生じることがない。 FIG. 4 is a front view showing a collective control board in the third embodiment of the present invention. FIG. 5 is a front view of a single control board used separately from the collective control board in FIG.
In the first embodiment, the pattern 15 is drawn into the individual control boards 10A to 13A and connected to the zero ohm resistor pads 16 to 19. In the embodiment, the assembly control board 4A has the pads of the zero ohm resistance pads 16-19 disposed at the positions straddling the connecting portions 20-23 of the individual control boards 10A-13A. The zero ohm resistor pads 16-19 and the pattern 15 are connected outside the individual control boards 10A-13A.
In this case, the pattern 15 is not cut when the plurality of connecting portions of the collective control board 4A are separated and used as the single control board. Therefore, the problem of pattern corrosion does not occur in the single control boards 10A to 13A separated from the collective control board 4A.
