Brief description of calibration methods
Axis Calibration method
Axis Calibration is a standard calibration method for calibration of IRB 6700Inv and
is the most accurate method for the standard calibration. It is the recommended
method in order to achieve proper performance.
The following routines are available for the Axis Calibration method:
The calibration equipment for Axis Calibration is delivered as a toolkit.
An introduction to the calibration method is given in this manual, see
with Axis Calibration method on page
The actual instructions of how to perform the calibration procedure and what to
do at each step is given on the FlexPendant. You will be guided through the
calibration procedure, step by step.
Wrist Optimization method
Wrist Optimization is a method for improving reorientation accuracy for continuous
processes like welding and gluing and is a complement to the standard calibration
method.
The following routines are available for the Wrist Optimization method:

Description
The calibrated robot is positioned at calibration
position.
Standard calibration data is found on the SMB
(serial measurement board) or EIB in the robot.
For robots with RobotWare 5.04 or older, the
calibration data is delivered in a file, calib.cfg,
supplied with the robot at delivery. The file
identifies the correct resolver/motor position
corresponding to the robot home position.
Optimization of TCP reorientation perform-
ance. The purpose is to improve reorientation
accuracy for continuous processes like weld-
ing and gluing.
Wrist optimization will update standard calib-
ration data for axes 4 and 5.
