Calibration methods
Each calibration method is detailed in separate manuals. Below is a brief description of the
methods available.
Calibration Pendulum - standard method
Calibration Pendulum is the standard method for calibration of all ABB robots (except IRB
6400R, IRB 640, IRB 1400H and IRB 4400S) and is also the most accurate method for the
standard type of calibration. It is the recommended method in order to achieve proper
performance.
The calibration equipment for Calibration Pendulum is delivered as a complete toolkit,
including the manual Calibration Pendulum Instruction.
Levelmeter Calibration - alternative method
Levelmeter Calibration is referred to as the alternative method for calibration of ABB robots,
because of the less accurate values obtained during calibration. The method uses the same
principles as Calibration Pendulum but has not as good mechanical tolerances to the toolkit
parts as the standard method with Calibration Pendulum.
This method may, after calibration, require modifications in the robot program, and is
therefore not recommended.
The calibration equipment for Levelmeter Calibration is ordered as separate parts for each
robot and the manual Instruction for Levelmeter Calibration is enclosed with the Levelmeter
2000.
CalibWare - Absolute Accuracy calibration
In order to achieve a good positioning in the Cartesian coordinate system, Absolute Accuracy
is used as a TCP calibration. The tool CalibWare guides through the calibration process and
calculates new compensation parameters. This is detailed further in the manual CalibWare 2.0
Users Guide.
If a service operation is done to a robot with Absolute Accuracy, a new absolute accuracy
calibration is required in order to establish full performance. For most cases after motor and
transmission replacements that do not include taking apart the robot structure, standard
calibration is sufficient. Standard calibration also supports wrist exchange.
