摘要： A protecting method and apparatus for a regenerative resistor in which a regenerative resistor is satisfactorily protected from a thermal breakage caused by an over-regeneration by combining a projection of the regenerative resistor by a thermostat and a protection of the regenerative resistor by an analog simulation circuit and by coordinating protective regions of these two protections. The heat-responsive switch (2) stops power supply to a DC link (10) when the temperature of the regenerative resistor is increased to a predetermined value or greater value. The analog simulation circuit (1) is provided with a charge-discharge circuit to be charged and discharged in response to a regenerative pulse signal from a level detector (7), estimates the quantity of heat accumulated in the regenerative resistor (5) by means of the charge-discharge circuit, and stops power supply to the DC link (10) when a predetermined threshold value is exceeded by the estimated value. A fusing region of the regenerative resistor (5) is covered by at least one of the protective regions based on the heat-responsive switch (2) and the analog simulation circuit (1).

摘要： In a control apparatus, a “characteristic value calculation” block calculates a characteristic value (such as amplitude value, offset value, or waveform distortion for each phase of two-phase sinusoidal signals optically input from an encoder, or phase difference between the two phase signals) for each of the two-phase sinusoidal signals, and an “alarm detection” block checks the presence or absence of an excursion outside a predetermined allowable range and, if such an excursion is detected, produces an alarm indication or the like. Each time the “present characteristic value” is input, a “characteristic value comparison” block compares it with “previous characteristic values”, and analyzes the result of the comparison. That is, the difference between the present value and each previous data is calculated, and the largest amount of variation (with plus or minus sign) is obtained; if this amount is larger than a predetermined value, a signal indicating an “imminent failure” is output. In an alternative method, the present value is compared with a characteristic value calculated from an encoder reference signal. Further, the characteristic value monitoring and comparison may be performed within the encoder. In this way, data useful for the prediction of encoder failure, etc. is provided.

摘要： In the motor driving system, a unit to predict the separation of the wire is built into the power semiconductor module thereby to predict that the time of separation of the wire is approaching before the actual separation of the wire. Thus, the time to replace the power semiconductor module used for power devices such as the motor driving system is clarified to prevent an operation failure of the motor driving system from occurring. The power semiconductor module (1) has a power semiconductor chip (2) mounted thereon, and the power semiconductor chip (2) includes a main circuit wire (4) and a dummy wire (5) connected to the electrode (3) of the power semiconductor. The dummy wire is set to a lower connection strength than the main circuit wire.

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.
