EINRICHTUNG ZUR STEUERUNG DER RAHMENBEWEGUNGEN AN STICK-ODER NAEHAUTOMATEN

摘要

A device for control of the frame movements of embroidery or sewing automatic machines, by which the movements of the frame in the x and y direction are carried out by servomotors. The path information for displacement of the frame in the x and y direction are emitted by a microprocessor control, the latter comprising a central processing unit and a working random access memory, from which memory the path information is recalled on time in dependency on the program of a programmable read only memory and via the central processing unit with the intermediate connection of an input-output port being retransmitted to digital analog converters. The converters are connected with direct current motors of the frame via power units, the latter operating as amplifiers.
