Brief description of calibration methods
Axis Calibration method
Axis Calibration is a standard calibration method for calibration of IRB 1100. 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.

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.
Based on standard calibration, and besides
positioning the robot at synchronization posi-
tion, the Absolute accuracy calibration also
compensates for:
• Mechanical tolerances in the robot
structure
• Deflection due to load
Absolute accuracy calibration focuses on pos-
itioning accuracy in the Cartesian coordinate
system for the robot.
Absolute accuracy calibration data is found
on the SMB (serial measurement board) in the
robot.
A robot calibrated with Absolute accuracy has
the option information printed on its name
plate.
To regain 100% Absolute accuracy perform-
ance, the robot must be recalibrated for abso-
lute accuracy after repair or maintenance that
affects the mechanical structure.
• Fine calibration
• Update revolution counters
• Reference calibration
