Method for analyzing the status of an electromechanical joining system and electromechanical joining system for carrying out the method

A method for analyzing the status of an electromechanical joining system wherein an output force or output torque for a joining method carried out by the electromechanical joining system is generated by an electrical drive by means of a screw drive, the method comprising the steps of:

• supplying actual values of the electrical drive as input variables to a monitoring device that uses an algorithm;
• using a sensor to determine additional measurement values from the course of forces or torques over time during the joining method;
• supplying the monitoring device is supplied with the additional measurement values as input variable;
• wherein the monitoring device uses the algorithm to generate a linkage between the actual values with and the additional measurement values;
• and
• wherein the monitoring device uses this linkage to detect upcoming wear of a wear-prone component of the electromechanical joining system.
