8 Calibration of Conveyer and Robot Coordinate Systems (“A1” program)

 

8-50  Preliminary Preparaions 

 

Tool length is calculated automatically by instructing in the location of 3-8 points as follows in the screen 

mentioned above. 

 

 

 

 

 

 

8.1.2.

 

Confirm the encoder value 

An important one is a change in the encoder value in this work. Confirm whether a robot controller grasps the 

turn of the encoder. 

 

From the project tree, click the target project [Online] -> [Monitor] -> [Movement Monitor] -

> [Program Monitor], 

then double click the "Task slot" to monitor.
