摘要： A motor driving apparatus capable of detecting during operation a ground fault and a phase-to-phase short circuit by distinguishing one from the other is provided while minimizing an increase in cost. The sum of three-phase AC currents supplied from a three-phase AC power supply to an AC/DC converter is detected by a current sensor. When overcurrent is detected by an overcurrent detector, if the sum of the currents detected by the current sensor is zero, it is determined that the fault is a phase-to-phase short circuit, but if the sum is not zero, it is determined that the fault is a ground fault.

摘要： When the output of motor reaches or exceeds a predetermined value during acceleration of the motor, the control target value of the DC link voltage which is the voltage of a power storage device is gradually lowered in corresponding relationship to the motor output. When the motor enters a constant speed control mode, the DC link control target value is maintained at a constant level. When the motor enters a deceleration control mode, the DC link control target value is gradually raised in corresponding relationship to the motor output, and regenerative power is recovered by the power storage device and reused in the next control cycle.

摘要： During motor acceleration control period that starts at time T1, if power supply output or supply current exceeds a predetermined level at time T2, PWM control in a PWM converter is turned off until a deceleration control period of T3 to T4 ends. As a result, DC link voltage (voltage of a power storage device) at the start of the deceleration control at time T3 drops to provide space for storing regenerative power; since the PWM control in the PWM converter is off during the deceleration control period, the regenerative power can be stored into the power storage device and reused in the next control cycle.
摘要翻译： 在时刻T1开始的电动机加速控制期间，如果电力供应输出或电源电流在时间T2超过预定电平，则PWM转换器中的PWM控制被截止，直到T3至T4的减速控制周期结束。 结果，在时刻T3的减速控制开始时的直流链路电压（蓄电装置的电压）下降，提供存储再生电力的空间; 由于PWM转换器中的PWM控制在减速控制期间关闭，所以再生功率可以存储到蓄电装置中并在下一个控制周期中重新使用。

摘要： In a controller where a contour machining is performed through a synchronous control between a mechanically movable portion (servo axis) driven by a servo motor and a main shaft (spindle axis) driven by a spindle motor, the position of the servo axis and the position of the spindle axis are collected at the same timing for each predetermined cycle and are stored. The position data of the servo axis and the spindle axis stored are converted to obtain a machining contour shape data, and the shape obtained is displayed on a display device of a personal computer or the like.

摘要： A method for estimating a load acting on a machine tool and controlling a life of the machine tool based on the estimated load. When predetermined machining is effected on a predetermined workpiece, a disturbance load torque acting on a motor for a spindle or a motor for a feed shaft is estimated by a disturbance estimating observer. When the estimated disturbance load becomes not lower than a set reference value, a timer is reset and started. If the estimated disturbance load torque is kept not smaller than the set reference value until the timer reaches a predetermined set time, a tool change command is issued to stop the machining. Since the tool life is determined in accordance with the magnitude of the load acting on the tool, the tool life is controlled objectively and accurately.
