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.
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.
For robots with RobotWare 5.05 or older, the
absolute accuracy calibration data is delivered
in a file, absacc.cfg, supplied with the robot at
delivery. The file replaces the calib.cfg file and
identifies motor positions as well as absolute
accuracy compensation parameters.
A robot calibrated with absolute accuracy has
a sticker next to the identification plate of the
robot.
To regain 100% absolute accuracy perform-
ance, the robot must be recalibrated for abso-
lute accuracy!

The robot is calibrated by either Calibration Pendulum or Axis Calibration at factory. Always use
the same calibration method as used at the factory.
Information about valid calibration method is found on the calibration label or in the calibration
menu on the FlexPendant.
If no data is found related to standard calibration, Calibration Pendulum is used as default.
