[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multifunctional encoder, and more particularly to a new improvement for multifunctioning by selectively reading various data stored by inputting encoder position data.

[0002]

[Prior art]

 As an encoder of this type which has been conventionally used, for example, the configuration disclosed in Japanese Patent Application Laid-Open No. 62-278408 can be cited. That is, the signal output using the slit pattern of the rotating disk is encoder position data, and no multifunctional data other than this encoder position data is output.

[0003]

[Problems to be solved by the device]

 Since the conventional encoder is configured as described above, there are the following problems. In other words, since only encoder position data is output as a signal, for example, when controlling the rotation of a motor, speed data and the like must be calculated on the controller side of data using only position data. The information processing on the controller side was complicated.

The present invention has been made to solve the above problems, and in particular, it is made multifunctional by selectively reading various data stored by inputting encoder position data. It is an object of the present invention to provide a multi-functional encoder that has been designed as described above.

[0005]

[Means for Solving the Problems]

 The multifunctional encoder according to the present invention comprises a communication gate array for inputting encoder position data output from the encoder body, and at least one rotation data, multi-rotation data and speed / acceleration provided in the communication gate array. Data, a selector unit to which each data described above is input, a data type recognition unit and a parallel / serial conversion unit connected to the selector unit, and by inputting a request signal to the data type recognition unit The parallel / serial converter is configured to output a serial signal.

[0006]

[Action]

 In the multifunction encoder according to the present invention, when an arbitrary request signal is input to the data type recognition unit, this recognition data is input to the selector unit, and at this selector unit, at least one rotation data, multiple rotation data, speed / acceleration is received. Any one of the data is selected and read out, and is output as a serial signal via the parallel / serial conversion unit. Therefore, by increasing the types of each data stored in the communication gate array, it is possible to obtain an extremely large number of data output functions.

【Example】

 Hereinafter, preferred embodiments of a multifunctional encoder according to the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 indicates an encoder body, and encoder position data 1 a, which is angle data from the encoder body 1, is input to the communication gate array 2.

The communication gate array 2 stores at least one-rotation data 3, multi-rotation data 4, speed / acceleration data 5 as data, and outputs 6 a of a free-run cyclic counter 6 and an alarm status 7. , 7a and each of the data 3 to 5 are input to a selector unit 8, and a data type recognition unit 9 and a parallel / serial conversion unit 10 are connected to the selector unit 8.

A request signal 11 is input to the data type recognition unit 9, and a serial signal 12 is output from the parallel / serial conversion unit 10.

Therefore, in the above-mentioned configuration, in the communication gate array 2, the data and the data 3 to 5 and the outputs 6a and 7a are stored and converted so as to be output based on the encoder position data 1a, and the selector unit It is entered in 8.

In the above-mentioned state, when the request signal 11 is input to the data type recognition unit 9 and the recognition data 9a is input to the selector unit 8, the selector unit 8 uses any of the above-mentioned recognition data 9a based on the recognition data 9a. The data 3 to 5 and the outputs 6a and 7a are selected and output as a serial signal 12 via the parallel / serial converter 10.

Therefore, not only the encoder position data 1a but also various data 3 to 5 and outputs 6a and 7a can be obtained by the request signal 11, and a multifunctional signal can be taken out from one encoder body 1. .

[0013]

[Effect of device]

 Since the multifunctional encoder according to the present invention is configured as described above, the following effects can be obtained. That is, since various types of data can be selectively taken out, control of the side using the encoder signal (for example, a motor) becomes easy, and simplification of the control system can be achieved.
