Applicator comprising an integrated control circuit

A coating robot, comprising:

• an applicator including several nozzles configured for application of coating agent in the form of a coating agent jet, a plurality of coating agent valves for controlling the release of the coating agent through the individual nozzles, and a plurality of electrically controllable actuators for controlling the coating agent valves;
• a control circuit for electrically driving the actuators, the control circuit integrated in the applicator;
• a robot controller for program control of the coating robot;
• a graphics module for specifying switching patterns for the actuators in accordance with a predefined graphic;
• and
• at least one cable between the robot controller and a printhead logic, the cable comprising the following connections:
• a) a power voltage supply for the actuators,
• b) a control voltage supply for the printhead logic and the power electronics,
• c) potential equalization;
• and
• d) a communication connection for connection to the robot controller.
