摘要:
A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

To provide a display device displaying an error between an instructed command position of a specific portion of a control target and a response position of the specific portion in a manner easily understandable to a user. The display device acquires a response position of a specific portion based on a command value, and calculates a difference in position of the command position and the response position. The display device determines whether or not the difference is greater than or equal to a threshold value. The display device displays on a screen a spatial trajectory based on the command position or a spatial trajectory based on the response position, and a mark indicating a portion of the trajectory in which the difference is determined to be greater than or equal to the threshold value. The display device also displays each spatial trajectory on a screen (11) in a mode where a portion of the spatial trajectory of the command position corresponding to the selected mark (FB 9) and a portion of the spatial trajectory of the response position corresponding to the relevant portion of the spatial trajectory of the command position are enlarged at a same magnification, the mode being such that each enlarged portion of spatial trajectory overlaps each other.

Nach einem erfindungsgemäßen Verfahren zur modellbasierten Regelung eines Manipulators, insbesondere eines Roboters wird eine Soll-Kraft eines Aktuators des Manipulators auf Basis eines Modells des Manipulators bestimmt und der Manipulator mit dieser Soll-Kraft durch den Aktuator beaufschlagt. Dabei wird eine vom Manipulator ausgeübte virtuelle Kraft auf Basis des Modells des Manipulators und eine vom Manipulator ausgeübte reale Kraft sowie die Differenz zwischen ausgeübter virtueller und realer Kraft bestimmt und diese mit einem Maximalgrenzwert verglichen. Nur falls der Vergleich ergibt, dass die Differenz kleiner als der Maximalgrenzwert ist, wird der Manipulator mit der auf Basis des Modells des Manipulators bestimmten Soll-Kraft beaufschlagt.

An anomaly detecting method in a servo system that is capable of quickly detecting the occurrence of an anomaly even in a low revolution range is disclosed. A simulator (14) finds a position feedback (PAS) by integrating a speed instruction (Vcs) which is equal to the product of a position loop gain (PG) and an estimated position deflection (Ers) that is obtained by subtracting the position feedback (PAS) from a movement instruction (Mc) while the servo control for the servo motor is executed by the digital servo control units (11 to 13) according to a torque instruction (Tc) calculated based on the speed feedback (VA) and a speed instruction (Vc) that corresponds to a practical position deviation (Er). An extraordinary error detecting unit (15) compares a predetermined value (As) with the error (Er - Ers) between the practical position deviation and an estimated position deviation. In case any anomaly has occurred, the practical position deviation increases but there is no substantial change in the estimated position deviation generated by the simulator that approximately carries out normal servo control, whereby a difference between them reaches a predetermined value that indicates the occurrence of an anomaly and alarm is set off.

A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

摘要:
A method for the preventive detection of failure in at least one apparatus to be monitored in a group comprising at least two apparatuses, the apparatus to be monitored comprising at least one first parameter correlated with at least one second parameter of at least one second apparatus of the group, said parameters representing status variables of said apparatus. The method comprises the following steps: predicting a value of the first parameter from a measured value of the second parameter; comparing the predicted value of the first parameter with a measured value of the first parameter; and analysing the result of the comparison made in the comparison step to detect a possibility of failure. The invention also relates to a computer program, a system and a module for the preventive detection of failure in an apparatus.

The invention relates to a system for correctly placing glass containers formed by the sections of an I.S. machine onto a conveyor. A pusher mechanism (138) moves containers from a deadplate to the conveyor. A container placement measurement system (142) provides a measured placement signal (144) indicative of the actual locations of containers moved onto the conveyer by the pusher mechanism. A summer (148) compares the measured placement signal (144) with a desired container placement signal (146) and generates a container placement error signal (150). A control system (152, 159, 156) uses the error signal (150) to provide modified pusher parameters to vary the operation of the pusher mechanism in a manner that will cause the error signal to be diminished.
