    • A method for emulating programs in a system includes a plurality of first and second data processors having different instruction word sets. An instruction which interrupts the operating system on the first data processor is defined. When the instruction is detected in a program running on the first data processor, it is determined whether or not the instruction is an instruction associated with an input/output macro instruction. If it is found, as a result of the determination, that this is the case, an interrupt is caused in a program running on the second data processor which controls the emulation, and the input/output macro instruction output from an emulated program is translated into an input/output macro instuction for the operating system, thereby implementing an emulation with a minimized overhead.

    • A system employed in a machine tool of the type in which a gear mechanism disposed between the spindle and spindle motor transmits the rotational motion of the motor to the spindle. The system allows the spindle to be brought to a stop at a predetermined rotational position in a shorter period of time when the gear mechanism is set in low gear, that is, while the rotational speed of the motor is being reduced by the gear mechanism as it is being transferred to the spindle. This permits the spindle to be stopped at the predetermined position in the same amount of time which is required when no reduction in speed takes place between the motor and spindle. When the spindle arrives at a region where it is to be controlled in order to stop at the predetermined rotational position, a position deviation signal for guiding the spindle to the position is applied as an input signal to a speed control loop for controlling spindle rotation. The position deviation signal varies in dependence upon the gear ratio of the spindle gear mechanism. Positioning gain, which is obtained by dividing the speed of the spindle motor by an amount of spindle motor rotation that depends upon the position deviation of the spindle; is controlled so that it remains constant regardless of the speed change ratio between the spindle and spindle motor as determined by the gear mechanism.
    • 一种用于机床的系统,其中设置在主轴和主轴电机之间的齿轮机构将电动机的旋转运动传递到主轴。 该系统允许主轴在齿轮机构设定为低档时,即在通过齿轮机构减小电动机的转速的同时,在更短的时间内使预定旋转位置停止, 它正在转移到主轴。 这允许主轴在电机和主轴之间不发生速度降低所需的相同的时间量内停止在预定位置。 当主轴到达要控制的区域以便在预定旋转位置停止时,将用于将主轴引导到位置的位置偏差信号作为输入信号施加到用于控制主轴旋转的速度控制回路。 位置偏差信号根据主轴齿轮机构的齿轮比而变化。 定位增益,通过将主轴电动机的转速除以主轴电动机的旋转量取决于主轴的位置偏差而获得; 被控制,使得其保持恒定,而与齿轮机构确定的主轴和主轴电机之间的速度变化率无关。

    • A spindle motor control method capable of high-accuracy contour machining uses a vector control processor executing a speed loop process to obtain a torque command (Tc). Vector control is performed (S4, S7) in accordance with a magnetic flux command (.PHI.c) set at a predetermined fixed value (CF.PHI.) when a spindle motor is being driven in a contour control mode. This prevents irregularity in motor speed and motor vibration attributable to a delay of the actual magnetic flux of the spindle motor behind the magnetic flux command, thus enabling high-accuracy contour machining. In a normal speed control mode or an orientation mode for tool replacement, the vector control is effected (S4 to S6, S8) in accordance with the magnetic flux command (.PHI.c), which is obtained on the basis of the torque command (Tc), its maximum value (Tcmax), maximum magnetic flux command (.PHI.cmax) set in dependence on the rotating speed of the motor, and minimum magnetic flux (NR.PHI.cmin, OR.PHI.min).
