Upgrade of the control system for the spring winding machine:
replacement of the main drive for the winding shaft with an Emerson converter, replacement of the old controller, programming of positioning functions for 4 axes, replacement of distance measurement systems – implementation of magnetic encoders, replacement of angle and rotational speed measurement systems – implementation of an incremental encoder, replacement of the control panel equipped with a distributed input/output station and a graphic terminal with recipe management for wound springs. implementation of 1 master axis and the electronic gearbox function, with dynamically changing parameters, for the remaining axes. implementation of the winding process with an accuracy of 1 mm across the entire height of the spring.
