Technology used

Safety, motion control, hmi

Distinctive elements

The axes work following a cam profile calculated based on the format to be machined. The synchronism master is an external encoder mounted on the flywheel, this allows the mechanics of the axes to be minimized because their dynamics will depend on the current speed of the flywheel and will not be controlled at maximum speed as was the case with the previous electronics.

Customers benefits

Maintaining the mechanics of the machines of the 90s, but changing all the electronic parts from an embedded to a commercial one, it is possible to obtain a 25% increase in speed (passing from 90CPM to 125CPM) and an increase in productivity from 85 to 95%.
