Screwdriving Controller

Besides the screwdriver, the screwdriving controller is an essential component of the electronic screwdriving system. According to the parameterized screw-tightening process, the controller controls the EC-drive of the screwdriver, evaluated the measuring signals and provides all necessary operator- and documentation functions.

The offered EC- and EC-Servo systems are both equipped with highly dynamic brushless servo-motors; they differ in the way the torque measurements are generated.
While the EC-technology used with the sequence controllers AST5 and AST11 are based on the exact motor-current measurement, the EC-Servo system with the controller AST30-31 and AST40 evaluates the signals of the transducer integrated in the tool.

Additional selection criteria’s for the application-specific and best-suitable screwdriving system – besides the torque values – are the different possibilities for the documentation of the screwdriving-result, as well as the diverse interface to integrate with the system environment.

Function Controllers – fc

Function controllers are used to the increase of the process reliability in the manual screw-assembly. They allow the supervision of each individual tightening-process and guarantee the completeness of the screw-connection on a given product.

Screwdriver Function Control fc11

Screwdriver function control fc11 and the handheld xcrewdrivers of the MICROMAT-F/MINIMAT-F series offer an intelligent, process reliable solution.

This screwdriving system counts the assembled screws, monitors their screwdriving time, shuts off only when the preset torque is reached and recognizes a part-change – it controls itself 100 % and eliminates an expensive inspection.

Screwdriver Function Control fc20

The fc20 can also monitor complex assembly processes using programmable sequences. The controller can also manage up to 3 different screwdriver model connections for complex multi layer assemblies, which may require different screws and torques.
