5.2 Calibration method
Overview
This section specifies the different types of calibration and the calibration methods
that are supplied by ABB.
Types of calibration
Calibration method
Description
Type of
calibration
Calibration by hand
with activated brake
release, using the calib-
ration marks.
Standard calibration is performed if resolver
values are changed or the robot is rebuilt (see
).
The robot is positioned at calibration position,
that is when the positions of the axes 1-3
(angles) are set to parameter values found in
Calibration Position

.
Standard calibration
Standard calibration data is found on the SMB
(serial measurement board) 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.
Ring calibration
A factory reset (calibration with a calibration
ring) can be performed after a gearbox or an
upper arm has been replaced to ensure en-
hanced robot arm accuracy than when perform-
ing standard calibration. Factory reset alters
the robot's unique production settings for axis
1-3.
Factory reset
To perform ring calibration, the parallel arms
must first be removed from the robot. The up-
per arms must then be positioned vertically
so that the calibration ring can be fitted to
them.
Making a factory reset with the calibration ring
requires specific calibration equipment and
software, and is performed by ABB. Please
contact ABB.
The parameter
Calibration Position
(cal_posi-
tion) is set at the ABB factory, and is a robot
specific parameter. For more information about

Calibration methods
The calibration method for the IRB 360 is different from other robots, and normal
calibration methods are not applicable.
