Table 4-5 Items to check during automatic calibration
Whether the corresponding point is set
correctly.
For example, Whether the order of the
argument of the instruction that sets the
corresponding
point is wrong. The calibration
number is incorrect.
Please correctly set corresponding points.
Whether OVRD speed is too high.
Please set the OVRD speed to 10% or less.
Whether there is interference light.
Please block it if there is interference light.
Whether lens distortion does not occur in
recognition image.
Perform lens distortion correction.
Please use lens that lens distortion is unlikely to
occur.
During calibration execution, Whether the
heights of the vision sensor and the robot
calibration marks changed.
Do not change the height between the vision
sensor and the mark for robot calibration.
Whether the mark for robot calibration is
specularly reflected and does not shine.
Please change the position to a non-specular
reflection.
Whether the vision sensor (optical axis of the
lens) is perpendicular to the operation range
(calibration range).
Set the vision sensor (optical axis of the lens) is
perpendicular to the operating range (calibration
range).
Whether the origin setting of the robot is
correctly set.
Please reset the origin of the robot.
Is the rotational component of the position data
in the unit setting parameter "PRGMDEG" set
to the factory setting "0" (unit: RAD)?
Set parameter PRGMDEG to "0".
