摘要： PURPOSE:To improve the stopping accuracy at the stop of a fixed position by delaying the braking period of a braking mechanism properly on the basis of the rotational frequency of a machine when a machine needle reaches a stop position. CONSTITUTION:A rotational frequency detecting signal TGS is delayed little by little by buffer circuits 1-3, resistors R1-R3 and capacitors C1-C3. The delayed variable is changed in accordance with the rotational frequency of the machine. When the machine needle reaches a prescribed position, a transistor (TR) 3 is driven by a signal delayed for a period corresponding to the rotational frequency of the machine at a moment just before reaching to the prescribed position and current is made flow into a brake coil BR to work the braking mechanism. Thus, the working period of the braking mechanism is properly delayed in accordance with the rotational frequency at the reach of the machine needle to the prescribed position, so that the stopping accuracy at the stop of the fixed position can be improved.

摘要： PURPOSE:To decide a positioning mode in response to control needs and to ensure a positioning job with high accuracy, by setting variably with a command the width of a position signal which shows that a control shaft driven by a servo motor enters an area approximate to a target stop position. CONSTITUTION:A CPU118 of a positioning system controls each part, and a position control circuit 113 delivers a speed command to control a position according to a command pulse given from a command pulse generating circuit 116. This command is supplied to a speed control circuit 111, and a servo motor 101 is driven by the output of the circuit 111. Then the fixed position of a control shaft 105 of the motor 101 is detected by a position detector 106. The shaft 105 is set at its fixed position by a fixed position stop control circuit 107 and based on the output signal of the detector 106. Then the width of a position signal is set variably. This position signal shows that the shaft 105 enters an area approximate to a target stop position. Thus a positioning job is possible with high accuracy.

摘要： PURPOSE:To prevent malfunction by suppressing the operation of a means to generate a preset signal obtained by decoding an output from a counter during the presetting of the counter. CONSTITUTION:A ripple carrier type programmable counter consisting of FF f1-f8 executes its counting operation by an input signal fIN, and when the counted value reaches a prescribed value, sends a signal X2 to a shift register F9. The shift register F9 delays the signal X2 by a prescribed time, sends a signal Y2 to a Prn among the Pr terminals of the FF f1-f8 and sets up the data of terminals D1-D8. Since the signal X2 is obtained by connecting OR circuits G6, G7, G8 and an NOR circuit G9 as shown in the figure in this invention, the signal X2 is not outputted during the output of the signal Y2, preventing the malfunction.
摘要翻译：目的：通过抑制在计数器预置期间通过解码来自计数器的输出而产生预置信号的装置的操作来防止故障。构成：由FF f1-f8组成的波纹载波型可编程计数器通过输入信号fIN执行其计数操作，当计数值达到规定值时，向移位寄存器F9发送信号X2。移位寄存器F9将信号X2延迟预定时间，向FF f1-f8的Pr端子中的Prn发送信号Y2，并设置端子D1-D8的数据。由于信号X2是通过连接OR电路G6，G7，G8和NOR电路G9得到的，如本发明的图所示，信号X2在信号Y2的输出期间不输出，从而防止故障。

摘要： PURPOSE:To make a safe and smooth motion possible by setting two limit points, where a stop command and a decelerating command are given respectively, in a maximum operating range. CONSTITUTION:Current positions of moving arms 1a and 1b are operated in a controller at intervals of a minute time by a current positioln operating part 5, and results are transferred to a comparing part 9 and a moving command operating part 7. The operating part 7 calculates extents of the next movement on a basis of data of the operating part and data from a movement objective position storage part 8 and outputs them to gates (c) and (d). Simultaneously, data from a limit position storage part 6 of an operating range 4 is compared with data of the operating part 5 to discriminate whether current positions of arms 1a and 1b are within the range 4 or at limit points. In accordance with this discrimination result, one gate is opened and the other is closed, and deceleration is operated in a deceleration operating part 11 to start deceleration, and arms are stopped quickly without getting out of the operating range when they reach stop points 2a.
