摘要： In a controller, V axis and W axis for driving a driven body (3) are tilting, not orthogonal to each other. An acceleration detector (7) capable of detecting accelerations in a plurality of directions orthogonal to the driven body (3) is arranged so that W-axis direction may meet Y-axis direction of an acceleration detected by the acceleration detector. An acceleration (Av) in the V-axis direction is determined by making calculations from accelerations (Ax,Ay) in X-axis and Y-axis directions detected by acceleration detectors (7). Based on the determined accelerations (Av,Aw) in the V-axis and W-axis directions, a position command, a speed command or a current command to servo motors (2v,2w) driving the V axis and W axis is corrected. Such correction suppresses the driven body (3) from generation of vibrations.

摘要： A device (110) for judging the collision of a slide (24) with a die cushion in a die cushion mechanism (20) which produces a force against the slide in a press machine using a servo motor (18) as a drive source, comprising force detection means (21) for detecting a force produced between the die cushion and the slide; and comparator means (95) for comparing a force detection value (Fd) detected by the force detection means with a predetermined threshold value (L1); wherein, when the force detection value becomes greater than the threshold value, it is so judged that the slide has come into collision with the die cushion. Thus, the collision is judged within a short period of time and reliably. The collision may be judged by comparing differentiated values (Fd', Fd") of the force detection value, slide position detection value (Y1d) or slide position instruction value (Y1c) or other related threshold values. There can be further used a system for judging a collision which executes a plurality of methods for judging the collision.

摘要： A controller for a servomotor capable of improving accuracy of positioning and quality of a machined surface by switching modes of correction of a position command or the like, and reducing a shock at the time of switching. A correction amount generating section obtains a correction amount based on a value of a correction factor such as machine temperature. When the external signal is in ON state, a position command or the like is corrected by the correction amount obtained by the correction amount generating section and sent via switches. A correction amount holding section holds the correction amount obtained by the correction amount generating section. When the external signal turns to OFF state, the connection of the switches is changed so that correction is performed by the correction amount held in the correction amount holding section. When the connection of the switches is changed, the correction amount does not change rapidly, so that the machine does not suffer a shock. In positioning, the external signal is turns to ON state, so that the positioning is carried out accurately by performing correction by the correction amount sent from the correction amount generating section. When a high-quality machined surface is required, the external signal is turned to OFF state so that the correction amount does not change to achieve improvement in the quality of a machined surface.
