    Abstract: Systems and methods for processing sensor information obtained from a coding wheel of a motor may detect defects in the sensor information caused by contamination or damage of any of the angular step markers, index marker, and/or blank space on the tracks of the coding wheel. A step counter counts toward an overflow value representing the number of angular step markers on the coding wheel. The step counter and the index are correlated: when the overflow value is reached, if the index marker is not detected an error is raised; coincidently, when the index marker is detected, if the step counter has not reached the overflow value an error is raised. The systems and methods may be applied to bidirectionally rotating motors and other devices by detecting a change in rotational direction and switching from incrementing the angular step counter to decrementing it, and vice versa.

  • Patent number: 9862094
    Abstract: A numerical controller and a robot controller share interpolation level move data obtained by recording position information for each interpolation period of a robot in association with an index. Based on the interpolation level move data, a preceding position of the robot after the passage of a time (lead time) for calculating a next preceding position since a reference time for interference check is calculated. And, based on the robot preceding position and a preceding position (machine preceding-position) of an axis of the machine after the passage of the lead time, interference between a machine and the robot is checked.

  • Patent number: 9645217
    Abstract: A method of determining a positioning error of a CNC machine is provided and an system thereof. A calibration element is placed within the CNC machine. A first sensor reading is taken of the calibration element. A second sensor reading is taken and the sensor is moved in a manner that the difference between the first and second sensor data decreases until the difference becomes less or equal to a pre-determined threshold value. A positioning error of the tool head is determined based on the movement of the sensor.

    Abstract: A robot apparatus includes a manipulator including a hand and an arm, a teaching apparatus that teaches operation of the manipulator, and a control apparatus that controls the manipulator that operates in a regular operation status or an erroneous manipulation avoiding status based on a control signal from the teaching apparatus. After determining whether a status of the manipulator is the regular operation status or the erroneous manipulation avoiding status, the control apparatus transmits a control signal for performing operation at a set regular speed to the manipulator in a case of the regular operation status, and the control apparatus transmits a control signal for performing operation at a speed lower than or equal to a safety speed that is set based on the regular speed to the manipulator in a case of the erroneous manipulation avoiding status.

  • Patent number: 9520734
    Abstract: A control apparatus is used for a power-supply apparatus with power-supply systems connected in parallel between a pair of power wires connected to a load. Each power-supply system has a series circuit of a battery and a contact of a relay. When the control apparatus determines that at least one relay suffers from a contact welding, the control apparatus performs a battery charge/discharge process to charge/discharge the batteries through the pair of power wires by turning ON one of possible relays while turning OFF the others of the possible relays. The possible relay is defined as having a possibility of suffering from the contact welding. After the battery charge/discharge process, the control apparatus identifies which possible relay actually suffers from the contact welding based on a change in a state of the battery connected in series with the contact of each possible relay.

  • Patent number: 9515585
    Abstract: A method for diagnosing an electric water pump of an internal combustion engine includes determining whether a present condition is a coil-open diagnosis condition that enables diagnosis of whether any coil of a sensorless 3-phase motor used in the electric water pump is open. When the coil-open diagnosis condition is satisfied, whether a coil of one phase is open is determined by using a change in phase currents. When the coil-open diagnosis condition is satisfied, whether coils of two phases are open is determined by using a magnitude of a motor torque or a magnitude of an average phase current. When the coil-open diagnosis condition is satisfied, whether any coil of the motor is open during driving of the motor is determined by using a variation in the motor torque.
