Numerical controller of full-closed-loop control system

Abstract

Abstract PURPOSE:To obtain a work track as commanded by moving a servomotor instantaneously by a back crush extent when the direction of axial movement is inverted. CONSTITUTION:A pulse generator 9 outputs a minus or plus pulse every time when movement commands are changed. Therefore, when the generator 9 outputs a minus pulse, a speed control part 4 moves the servomotor 5 in the minus direction instantaneously during the input of the minus pulse to correct the backlash extent of a machine 6. Similarly, when the plus pulse is inputted to the speed control part 4 from the generator 9, the servomotor 5 moves in the plus direction instantaneously to correct the backlash of the machine 6.
