摘要： A controller of an industrial machine provided with an electric motor, a peripheral apparatus and an amplifier includes a motor power-consumption calculation section, a power loss calculation section, a fixed power-consumption calculation section, and a total power-consumption calculation section. The motor power-consumption calculation section calculates motor power consumption by decomposing a motor current into a Q-phase current value and a D-phase current value, and multiplying the Q-phase current value with a motor rotation speed and a motor torque constant. The power loss calculation section calculates sum power loss of the motor and amplifier. The fixed power-consumption calculation section calculates fixed power consumption of the peripheral apparatus. The total power-consumption calculation section determines total power consumption of the industrial machine in a predetermined time period by integrating, for the time period, the calculated motor power consumption, sum power loss and fixed power consumption.

摘要： First and second screens are set for a tool path display apparatus for displaying a path of the tip of a tool attached to a machine tool. The first screen displays the three-dimensional path of the tip of the tool obtained by synthesizing the position information of the drive axes of a 5-axis machine tool. The second screen displays the waveforms of the position deviations and current instructions of the drive axes in chronological order. When a part (line segment) of the three-dimensional path of the tip of the tool is selected on the first screen, the display attribute of the corresponding time area is changed on the second screen so that the time area can be identified.

摘要： A control device, for a servo die cushion, by which the speed of a die cushion is prevented from largely deviating from the speed of a slide, whereby the press force between the slide and the die cushion is not significantly reduced. The control device includes a slide speed detector for detecting the speed of the slide, a die cushion speed detector for detecting the speed of the die cushion, and a die cushion speed commanding part for controlling the speed of the die cushion. When a tentative speed command of the die cushion is largely deviated from the detected slide speed, the command of the die cushion is corrected such that the absolute value thereof does not exceed the value calculated by adding the absolute value of the detected slide speed to a positive constant.

摘要： Abnormality of a position error is quickly detected in a control device in which feedforward control is introduced. A position error estimation processing unit calculates a position error estimation value Err, for example, from the equation V/PG×(1−α) (V: first order differential of position command, PG: position gain in position controller, α: feedforward coefficient in feedforward term calculating unit), and abnormality of the position error is detected using an excessive-error detection level calculating by adding a margin ΔE to the position error estimation value.
