<p>A maximum value -A of a position deviation, which is generated by deflection when a working point is moved in a +X direction, and a movement command D required till a deflection A in a opposite direction is again built up when the working point is reversed in a -X direction under the state where the maximum deflection -A is accumulated, are determined by measurement. Assuming that the deflection proportionally changes from -A to +A while the movement command is outputted by D, that is, while the actual position of the working point moves by D - 2A, a correction value is determined on the basis of the ratio of twice the deflection A with respect to (D - 2A) and the movement command value after the reversing of the moving direction, and this correction value is added to the movement command value and outputted as a movement command value. <IMAGE></p> |
