4 Calibration
If the parts of the robot (motor, reducer, timing belt, etc.) are replaced,
there will be a deviation between the origin stored by each motor encoder and
the origin stored by the controller, and the correct positioning cannot be
performed. The origin is the reference of the robot coordinate system. Without
the origin, the robot cannot judge its position. Therefore, in order to obtain the
highest possible absolute positioning accuracy, the robot must be calibrated (the
operation where the two origin positions are the same is called calibration) .
Robots are specially calibrated before they leave the factory. Generally,
recalibration is required in the following cases:
After replacing the parts of the robot (motor, reducer, timing belt, etc.).
Collision with the work-piece or environment.
Move the robot joints without being under the control of the controller.
Replace the encoder data backup battery.
Other conditions that may cause zero point loss.
