The controllers that are integrated in our automated screwdriving systems, are basically divided into screwdriving and process control systems. The screwdriving process controller monitors and controls the actual screwdriving process – it ensures that the preset speed, torque and depth are being maintained. In particular, the controller is important in evaluating the process and documentation of all screwdriving data. Process controllers are responsible for the control of the entire system. For example, they control the stroke movement of the screwdriving spindle, the feeding of fasteners or the communication with peripheral devices.
