以下，依據較佳的實施形態並參閱圖式的同時對本發明進行說明。將各圖式中所示之相同或相等的構成要件、構件、處理設為賦予相同符號者，適當省略重複之說明。又，實施形態為例示，而非限定發明者，並且實施形態中所記述之所有特徵或其組合並非限定發明的本質者。
圖1是馬達控制系統(Motor Controlled System)100R的方塊圖。馬達控制系統100R具備複數個馬達102、複數個編碼器104、網絡106、控制器108及複數個逆變器裝置130。
編碼器104生成所對應之馬達102的旋轉狀態、具體而言顯示位置資訊之脈衝訊號S1 。脈衝訊號S1 包括位相偏移1/4週期之A相脈衝及B相脈衝。
逆變器裝置130的驅動部132依據脈衝訊號S1 獲取馬達102的位置資訊，且反映於馬達102的驅動控制。
馬達控制系統100R連接有應用程序固有的控制塊(以下，稱為應用塊)300。應用塊300中，獲取馬達102的旋轉狀態，有時欲用於控制或顯示。應用塊300具備一個或複數個周邊裝置302。有時因周邊裝置(例如微電腦)302的介面的動作速度的限制而無法直接接收由編碼器104生成之脈衝訊號S1 來進行解碼。
為了解決該問題，在逆變器裝置130中設置分頻器134。分頻器134以適當的分頻比N分頻來自編碼器104的具有第1頻率f1 之脈衝訊號S1 ，並生成具有第2頻率f2 (f2 =f1 /N)之脈衝訊號S2 。在逆變器裝置130中構裝分頻器134的功能，藉此能夠緩和可追加到馬達控制系統100R的周邊裝置302的限制。
複數個周邊裝置302需要馬達102的旋轉資訊之情況下，並不限制於能夠由複數個周邊裝置302接收的脈衝訊號的頻率相同。例如周邊裝置302A設為能夠接收第2頻率的脈衝訊號S2 ，周邊裝置302B設為能夠接收第3頻率f3 (f3 ＜f2 )的脈衝訊號。該種情況下，藉由訊號分配器150將脈衝訊號S2 分支成2個系統，將其中一個供給到周邊裝置302A，將另一個供給到分頻器152。分頻器152以分頻比M分頻脈衝訊號S2 ，並生成第3頻率f3 (=f2 /M)的脈衝訊號S3 而供給到周邊裝置302B。
另外，圖1的馬達控制系統100R中，若增加周邊裝置302的數量，則訊號分配器150及分頻器152的個數增加，馬達控制系統100R的成本變高。該問題藉由以下說明之技術來解決。
圖2是表示實施形態之馬達控制系統100的基本構成之方塊圖。馬達控制系統100具備複數個馬達102、複數個編碼器104、網絡106、控制器108及複數個逆變器裝置200。圖2中，為了容易理解，僅表示與2個馬達102A、102B對應之2個系統，但是本發明中馬達的個數(系統的規模)並不限定於此，能夠擴張到3以上的任一數量。本說明書中，添加的A、B……表示系統的編號，通用為#或者*。
網絡106連接第1逆變器裝置200A與第2逆變器裝置200B。網絡106連接整體控制馬達控制系統100之控制器108。逆變器裝置200A、200B依據來自控制器108的控制指令來驅動馬達102A、102B。
第1編碼器104A、第2編碼器104B生成表示所對應之第1馬達102A、102B的旋轉狀態之輸出脈衝POUT A、POUT B。各輸出脈衝POUT 包括位相偏移1/4週期之A相脈衝及B相脈衝。例如輸出脈衝的計數表示轉子的位置，A相脈衝與B相脈衝的位相的關係表示旋轉方向。
第1逆變器裝置200A與第2逆變器裝置200B經由網絡106來連接。
第1逆變器裝置200A構成為能夠依據來自第1編碼器104A的第1輸出脈衝POUT A來驅動第1馬達102A，並且輸出頻率低於第1輸出脈衝POUT A的第1分頻脈衝PDIV A。
另外，第1逆變器裝置200A經由網絡106，能夠向第2逆變器裝置200B發送基於第1輸出脈衝POUT A之第1旋轉資訊DA。
另一方面，第2逆變器裝置200B依據來自第2編碼器104B的第2輸出脈衝POUT B來驅動第2馬達102B。又，逆變器裝置200B係構成為經由網絡106，能夠從逆變器裝置200A接收第1旋轉資訊DA，另外能夠輸出頻率低於由第1旋轉資訊DA表示之第1輸出脈衝POUT A的第2分頻脈衝PDIV B。
該例子中，第1分頻脈衝PDIV A的頻率係第1輸出脈衝POUT A的頻率的1/2，第2分頻脈衝PDIV B的頻率係第1輸出脈衝POUT A的頻率的1/4，但是各分頻比能夠依據各自的供給處的周邊裝置302A、302B的介面來任意設定。
周邊裝置302A依據第1分頻脈衝PDIV A來獲取第1馬達102A的旋轉資訊。周邊裝置302B依據第2分頻脈衝PDIV B來獲取第1馬達102A的旋轉資訊。周邊裝置302A、302B依據第1馬達102A的旋轉資訊能夠執行各種處理。例如周邊裝置302A、302B亦可以將第1馬達102A的旋轉資訊顯示於顯示器裝置304。
以上為馬達控制系統100的基本構成。藉由該馬達控制系統100，如圖1，不追加訊號分配器150或分頻器152，亦能夠生成頻率不同之複數個分頻脈衝。藉此，能夠減少系統整體的成本。
接著，對逆變器裝置200A、200B的構成例進行說明。
圖3是表示圖2的逆變器裝置200A、200B的構成例之方塊圖。
首先，對第1逆變器裝置200A進行說明。第1逆變器裝置200A具備驅動部202A、分頻單元204A及介面206A。驅動部202A依據來自所對應之第1編碼器104A的第1輸出脈衝POUT A來驅動所對應之第1馬達102A。
分頻單元204A生成具有第1輸出脈衝POUT A的1/NA 倍的頻率的第1分頻脈衝PDIV A。分頻比NA 可以為可變的。
介面206A接收來自控制器108的控制指令，並且能夠對第2逆變器裝置200B發送基於第1輸出脈衝POUT A之第1旋轉資訊DA。不易以脈衝列的形態經由網絡106將第1輸出脈衝POUT #傳送到其它逆變器裝置200B。因此，亦可以將第1輸出脈衝POUT A轉換成具有能夠由介面206發送的資料形式之第1旋轉資訊DA來發送。第1旋轉資訊DA例如能夠包括第1輸出脈衝POUT A的頻率資訊及包含於此之A相、B相脈衝的位相資訊。
接著，對第2逆變器裝置200B進行說明。第2逆變器裝置200B具備驅動部202B、分頻單元204B及介面206B。驅動部202B的功能與驅動部202A相同，依據來自所對應之編碼器104B的第2輸出脈衝POUT B來驅動所對應之第2馬達102B。
介面206B接收來自控制器108的控制指令，並且能夠從第1逆變器裝置200A接收第1旋轉資訊DA。
分頻單元204B依據第1旋轉資訊DA來生成具有第1輸出脈衝POUT A的1/NB 倍的頻率之第2分頻脈衝PDIV B。分頻比NB 可以為可變的。

例如分頻單元420包括選擇器422及分頻器424。分頻器424構成為能夠以所設定之分頻比分頻輸入脈衝，生成輸出脈衝。在第1模式中，選擇器422選擇來自所對應之編碼器104#的輸出脈衝POUT #，並供給到分頻器424。又，在第2模式中，選擇器422選擇從轉換部440供給之內部脈衝PINT 。內部脈衝PINT 為由DRX 表示之輸出脈衝。
轉換部440包括脈衝/資料轉換部442及資料/脈衝轉換部444。脈衝/資料轉換部442在第1模式中成為有效，將脈衝形式的輸出脈衝POUT #轉換成具有能夠由介面430發送的資料形式之旋轉資訊。資料/脈衝轉換部444在第2模式中成為有效，將由介面430接收之旋轉資訊DRX 轉換成內部脈衝PINT 。以上為逆變器裝置400的第1構成例。

In addition, the embodiment is an example and does not limit the inventor, and all the features or combinations described in the embodiment are not the ones that limit the essence of the invention.
FIG. 1 is a block diagram of a Motor Controlled System 100R. The motor control system 100R includes a plurality of motors 102, a plurality of encoders 104, a network 106, a controller 108, and a plurality of inverter devices 130.
The encoder 104 generates a pulse signal S 1 corresponding to the rotation state of the motor 102, specifically, the display position information. The pulse signal S 1 includes an A-phase pulse and a B-phase pulse with a phase shift of 1/4 cycle.
The drive unit 132 of the inverter device 130 obtains the position information of the motor 102 according to the pulse signal S 1 , and the position information is reflected in the drive control of the motor 102.
A control block (hereinafter, referred to as an application block) 300 specific to an application program is connected to the motor control system 100R. In the application block 300, the rotation state of the motor 102 is obtained, and sometimes it is intended to be used for control or display. The application block 300 includes one or a plurality of peripheral devices 302. Sometimes due to a peripheral device (e.g. a microcomputer) limits the operation speed of the interface 302 can not be received directly by the encoder 104 generates the pulse signal S 1 for decoding.
To solve this problem, a frequency divider 134 is provided in the inverter device 130. The frequency divider 134 divides the pulse signal S 1 from the encoder 104 with a first frequency f 1 by an appropriate frequency division ratio N, and generates a pulse signal with a second frequency f 2 (f 2 = f 1 / N). S 2 . By constructing the function of the frequency divider 134 in the inverter device 130, the restriction of the peripheral device 302 that can be added to the motor control system 100R can be eased.
When the plurality of peripheral devices 302 require the rotation information of the motor 102, the frequency of the pulse signals that can be received by the plurality of peripheral devices 302 is not limited. For example, the peripheral device can receive the second set 302A frequency pulse signal S 2, the peripheral apparatus 302B is set to be able to receive the third frequency f 3 (f 3 <f 2 ) of the pulse signal. In this case, the pulse signal S 2 is branched into two systems by the signal distributor 150, and one of them is supplied to the peripheral device 302A and the other is supplied to the frequency divider 152. Frequency divider 152 division ratio M divided pulse signal S 2, and generates a third frequency f 3 (= f 2 / M ) of the pulse signal S 3 is supplied to the peripheral apparatus 302B.
In addition, in the motor control system 100R of FIG. 1, if the number of peripheral devices 302 is increased, the number of the signal distributor 150 and the frequency divider 152 is increased, and the cost of the motor control system 100R is increased. This problem is solved by the technique described below.
FIG. 2 is a block diagram showing a basic configuration of a motor control system 100 according to the embodiment. The motor control system 100 includes a plurality of motors 102, a plurality of encoders 104, a network 106, a controller 108, and a plurality of inverter devices 200. In FIG. 2, for easy understanding, only two systems corresponding to two motors 102A and 102B are shown. However, the number of motors (system size) in the present invention is not limited to this, and can be expanded to any of three or more. Quantity. In this manual, A, B, etc. are used to indicate the number of the system, and are generally # or *.
The network 106 connects the first inverter device 200A and the second inverter device 200B. The network 106 is connected to the controller 108 of the overall control motor control system 100. The inverter devices 200A and 200B drive the motors 102A and 102B in accordance with a control command from the controller 108.
The first encoder 104A and the second encoder 104B generate output pulses P OUT A and P OUT B indicating the rotation states of the corresponding first motors 102A and 102B. Each output pulse P OUT includes an A-phase pulse and a B-phase pulse with a phase shift of 1/4 cycle. For example, the count of the output pulse indicates the position of the rotor, and the relationship between the phase of the A-phase pulse and the B-phase pulse indicates the direction of rotation.
The first inverter device 200A and the second inverter device 200B are connected via a network 106.
The first inverter device 200A is configured to be able to drive the first motor 102A based on the first output pulse P OUT A from the first encoder 104A and to output a first frequency-divided pulse having a frequency lower than the first output pulse P OUT A P DIV A.
In addition, the first inverter device 200A can transmit the first rotation information DA based on the first output pulse P OUT A to the second inverter device 200B via the network 106.

The second frequency division pulse P DIV B.
In this example, the frequency of the first frequency dividing pulse P DIV A is 1/2 of the frequency of the first output pulse P OUT A, and the frequency of the second frequency dividing pulse P DIV B is the frequency of the first output pulse P OUT A 1/4, but each frequency division ratio can be arbitrarily set according to the interfaces of the peripheral devices 302A and 302B at the respective supply points.
The peripheral device 302A obtains the rotation information of the first motor 102A based on the first frequency-divided pulse P DIV A. The peripheral device 302B obtains the rotation information of the first motor 102A based on the second frequency-divided pulse P DIV B. The peripheral devices 302A and 302B can execute various processes based on the rotation information of the first motor 102A. For example, the peripheral devices 302A and 302B may display the rotation information of the first motor 102A on the display device 304.
The above is the basic configuration of the motor control system 100. With the motor control system 100, as shown in FIG. 1, a plurality of frequency division pulses with different frequencies can be generated without adding a signal distributor 150 or a frequency divider 152. This can reduce the cost of the entire system.

It is not easy to transmit the first output pulse P OUT # in the form of a pulse train to the other inverter device 200B via the network 106. Therefore, the first output pulse P OUT A may also be converted into the first rotation information DA having a data format that can be transmitted by the interface 206 for transmission. The first rotation information DA can include, for example, frequency information of the first output pulse P OUT A and phase information of the A-phase and B-phase pulses included therein.
Next, the second inverter device 200B will be described. The second inverter device 200B includes a driving unit 202B, a frequency dividing unit 204B, and an interface 206B.
