Abstract
Official abstract text for this publication.
A servo controller ( 10 ) includes a reversal change calculating part ( 24 ) which uses the position of a moving member ( 19 ) as the basis to calculate the amount of change of the position of the moving member, a distance calculating part ( 25 ) which uses a position of the moving member as the basis to calculate a distance from the servo motor to the moving member, an approximation equation determining part ( 26 ) which uses the amount of change of the position of the moving member, distance, and the torque command as the basis to calculate a position correction amount which corrects delay of the servo motor due to reversal of the servo motor, and a position correction calculating part ( 27 ) which uses the approximation equation as the basis to calculate the position correction amount.
First claim
Opening claim text (preview).
The invention claimed is: 1. A servo controller which drives a threaded shaft of a ball screw which is connected to a servo motor so as to make a moving member which is engaged with said threaded shaft move, said servo controller comprising: a motor position acquiring part which acquires a position of said servo motor every predetermined control period, a moving member position acquiring part which acquires a position of said moving member said every predetermined control peri…
