摘要： A method and a device are provided for detecting the occurrence of a malfunction upon movement of an element by a driving system. While the element is being moved, a difference between a predetermined value and an actual value is determined at regular intervals by means of a processor. A derivative of the difference is determined by the processor at regular intervals. The difference and the derivative both fluctuate around an equilibrium value. Subsequently, only the values on one side of the equilibrium value of both the difference and the derivative are sampled. The sampled values are multiplied and the result is compared with a reference value by means of the processor. The occurrence of a malfunction is established if the result of the multiplication is higher than the reference value.

摘要： A method for protecting an electronic apparatus driven by a DC motor and a detection circuit for detecting positioning signals thereof. The electronic device includes an optical encoder, a code strip, and a DC motor. While moves along the code strip, the optical encoder outputs a first positioning signal and a second positioning signal for the control of the DC motor. The method includes the steps described below. First, states of the first and second positioning signals are detected. If the states of the first and second positioning signals are normal, the DC motor is controlled according to the first and second positioning signals. If the first positioning signal or the second positioning signal is abnormal, a preventive method is performed.

摘要： A fail-safe electronic position monitoring system for a motor is specifically described in a flame safeguard system. The same fail-safe system could be used more generally in any type of positional monitoring system using a potentiometer. The potentiometer and its wiper are monitored by a microcomputer which has stored in its memory a profile of at least three critical parameters. The parameters are a low voltage parameter, a high voltage parameter, and a parameter that deals with the rate of the voltage level change. The rate voltage level change includes monotonocity function.

摘要： A pre-process simulation may calculate operating conditions of a machine tool by simulating a NC program and calculate predicted values indicative of the operating conditions. A real time monitoring system may compare actual values from the actual operation of a machine tool actually executing the NC program to the predicted values and determine whether to initiate a response. The operating conditions may be machine tool operating conditions. The comparison of actual values to predicted values may be based on a dynamic limit within which the predicted values fall which may vary based on the tool position, and the dynamic limit may include upper and lower limit boundaries.

摘要： The operation state of a servo motor is monitored and output to a user before automatic termination of power to the motor. A servo system includes a servo motor and a safety unit. The safety unit cuts off electric power to the servo motor when at least one of a speed, a position, acceleration, an amount of movement, a movement direction, and torque of the servo motor is outside a first operation range. Furthermore, the safety unit outputs a warning when at least one of the speed, the position, the acceleration, the amount of movement, the movement direction, the torque is within the first operation range, but is outside a second operation range that is narrower than the first operation range. User controls allow reduced operation when outside the second operation range.

摘要： A manipulator includes: a drive section which electrically drives a joint; an instruction input section which executes instruction input; a control section which generates a driving signal in response to the instruction input; a sensor which detects an operation status of the joint or the drive section in time series; a setting section which sets an allowable operation range of the drive section; a determination section which determines whether an operation status signal including a detection signal is within the allowable operation range; and a replacement section which, in a case when the operation status signal is determined as deviating from the allowable operation range, replaces the detection signal with a previous detection signal acquired just before the determination of deviance in order to generate a driving signal.

摘要： Controlling a direct current motor driving an object by determining, if the object does not reach a target position, a reference velocity corresponding to a point of time from a predetermined velocity trajectory, obtaining a position of the object, calculating a current velocity of the object, and calculating a difference between the reference velocity and the current velocity. If the calculated difference is greater than a velocity error limit value, informing a user that an error has occurred.
