    • Selected switching devices (e.g., Tra and Trd) of an inverter are turned on to supply a current between selected phases. If the respective inclinations of current waveforms then detected by current detection circuits IR and IS are equal to a reference inclination, it can be concluded that the current detection circuit in a circuit through which the current then flows, switching devices, and motor windings are normal. If the inclinations of the detected current waveforms are "0" or smaller than the reference, it can be concluded that the current detection circuits, switching devices, or motor windings are abnormal. In such a case, an abnormal spot is identified by checking the inclinations of the waveforms of the current detection circuits in like manner after changing the switching device to be turned on. If the inclinations of the detected current waveforms are very much greater than the reference, cables or motor windings can be concluded to be shorted.

    • A feedback-type position control method by which position control can be effected properly and easily in various machines. A pulse number converter (5) obtains the sum of a remainder (Rn-1) for a preceding cycle and the product of the number (xn) of feedback pulses delivered from a pulse coder (4) within a predetermined period and a first conversion coefficient (A) (S1 to S3). If the sum is positive or zero, position feedback pulses corresponding in number to a quotient (yn') obtained by dividing the absolute value of the sum by a second conversion coefficient (B) are delivered, and a remainder (Rn') resulting from the division is stored as a remainder (Rn) used to obtain the sum for the next cycle (S4 to S8). If the sum is negative, the number of position feedback pulses is set at a value (-yn'-1) obtained by subtracting 1 from a value obtained by inverting the sign of the quotient, and a value (B-Rn') obtained by subtracting the remainder from the second conversion coefficient is used as the remainder (S9 and S 10). The significance of one position feedback pulse is brought to be equivalent to a movement of a machine movable section for one position command pulse, so that the position control of various machines can be effected by a pulse coder of one type.

    • A motor driving apparatus capable of drivingly controlling a plurality of inverter units with a single motor driving command from a motor control unit, and thereby control a large-capacity motor or the like. The motor control unit sends out a single motor driving command (torque command) S. An intermediary unit obtains motor driving commands S×A1 to S×A4 for the inverter units by multiplying the motor driving command S by each of coefficients A1 to A4 set in advance. The inverter units are fed with the motor driving commands S×A1 to S×A4 individually and drive a single motor. Since the motor is driven by the total current supplied by the inverter units, the motor can generate a large torque. The motor control unit only needs to generate a single motor driving command S, and hence only needs to operate a single processing part. Hence, the motor control unit can generate and send out motor driving commands for other motors to drive them.
    • 一种电动机驱动装置,其能够通过来自电动机控制单元的单个电动机驱动指令来驱动地控制多个逆变器单元,从而控制大容量电动机等。 电机控制单元发出单个电动机驱动指令(转矩指令)S.中间单元通过将电动机驱动指令S乘以系数A 1至A 4中的每一个来获得用于逆变器单元的电动机驱动指令SxA 1至SxA 4 提前。 逆变器单元分别供给电动机驱动指令SxA 1〜SxA 4,驱动单个电动机。 由于电动机由逆变器单元提供的总电流驱动,电动机可以产生大的转矩。 电机控制单元仅需要生成单个电机驱动指令S,因此仅需要操作单个处理部件。 因此,电动机控制单元可以生成并发送用于其他电动机的电机驱动命令来驱动它们。

    • 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.
