5.1.2 Calibration methods

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 actual instructions of how to perform the wrist optimization procedure is given
on the FlexPendant.
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 does not have as
good of 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 (Levelmeter 2000) for levelmeter calibration is ordered
as separate parts for each robot, and includes the Operating manual - Levelmeter
Calibration, which describes the method and the different routines further.
CalibWare - Absolute Accuracy calibration
The CalibWare tool guides through the calibration process and calculates new
compensation parameters. This is further detailed in the Application
manual - CalibWare Field.
If a service operation is done to a robot with the option Absolute Accuracy, a new
absolute accuracy calibration is required in order to establish full performance.
For most cases after replacements that do not include taking apart the robot
structure, standard calibration is sufficient.
The Absolute Accuracy option varies according to the robot mounting position.
This is printed on the robot name plate for each robot. The robot must be in the
correct mounting position when it is recalibrated for absolute accuracy.

The calibration equipment for Calibration Pendulum is delivered as a complete
toolkit, including the Operating manual - Calibration Pendulum, which describes
the method and the different routines further.
