System Configuration of the Sensor Tracking

Configuration of the sensor tracking is illustrated below.

The sensor tracking system is applied to pick up workpieces which are placed in the same arc with arbitrary interval on the moving conveyor.
The system executes two different programs simultaneously; one is a program to recognize the position of a workpiece and the other is a program to pick it up.

In a program which recognizes workpieces, the sensor activates trigger on once a workpiece passes through the sensor, and then the controller receives the encoder data and stores it at that moment.
In a picking up program, based on the stored data, the robot picks up a workpiece by adjusting the robot arm in response to the workpiece's motion.

Wiring diagram

Wiring diagram is illustrated below.

Encoder Hub

For encoder hub, there are old model and new model.

If you use a new model, connect the encoder line of the motor & encoder cable to the encoder hub's connector port indicated as "ROBOT-0" (on the left side viewed from the front).

For details about the external diagram and the precaution on installation, refer to "Encoder HUB".
