overloading the motors. If this is not done correctly operation stops may result.
References
Load diagrams, permitted extra loads (equipment) and their positions as specified in the

2.3.7. Suspended mounting
2.3.7. Suspended mounting
General
Initially the system is configured for mounting on the floor, without leaning. The method for
mounting the manipulator in a suspended position is basically the same as for floor mounting.
NOTE!
With inverted installation, make sure that the gantry or corresponding structure is rigid
enough to prevent unacceptable vibrations and deflections, so that optimum performance can
be achieved.
System Parameters
If the robot is mounted at any other angle, the system parameter “gravity beta” must be
updated. Gravity beta specifies the robot’s mounting angle expressed in radians.
NOTE!
It is very important to configure gravity beta correctly so that the robot system can control the
movements in the best possible way. Incorrect definition of mounting angle (gravity beta) will
result in:
•
Overloading the mechanical structure.
•
Lower path performance and path accuracy.
•
Some S4 functions will not work properly: e.g Load Identification & Collision
detection.
Mounting Angles and Values
The parameter “gravity beta” specifies the robot’s mounting angle in radians. It is calculated
in the following way for a mounting angle of 45°.
Gravity beta = 45° x 3.141593/180 = 0.785398 radians.

3 Maintenance
3.5.1. Oil change, gearbox, axes 5 and 6
WARNING!
Please observe the following before commencing any repair work on the manipulator:
•
Motors and gears are HOT after running the robot! Touching the motors and gears may
result in burns!
•
Turn off all electric power, hydraulic and pneumatic pressure supplies to the robot!
•
Take any necessary measures to ensure that the manipulator does not collapse as parts
are removed, e.g. secure the lower arm with fixtures if removing motor, axis 2.
TIP!
When changing gearbox oil, first run the robot for a time to heat up the oil. Warm oil drains
quicker than cold oil.
WARNING!
When filling gearbox oil, do not mix different types of oil unless specified in the instruction.
Always use the type of oil specified by the manufacturer!
WARNING!
When filling gearbox oil, do not overfill, since this could lead to internal over-pressure inside
the gearbox which in turn may:
•
damage seals and gaskets
•
completely press out seals and gaskets
•
prevent the manipulator from moving freely
WARNING!
Changing and draining gearbox oil may require handling hot oil of up to 90 °C! Make sure
that protective gear like goggles and gloves are always worn during this activity.
Also, be aware of possible pressure build up in gearbox! When opening the oil plug, there
may be pressure present in the gearbox, causing oil to spray from the opening!

5.1. Introduction
General
This chapter includes general information about different calibration methods and details also
procedures that does not require specific calibration equipment.
When the robot system must be recalibrated, it is done according to documentation enclosed
with the calibration tools.
When to calibrate
The system must be calibrated if any of the below occurs.
The resolver values are changed
If resolver values are changed, the robot must be recalibrated using the calibration methods
supplied from ABB. Calibrate the robot carefully with standard calibration. The different
methods are briefly described in section Calibration methods on page 164, and further
detailed in separate Calibration manuals.
If the robot has Absolute Accuracy calibration, it is also recommended but not always needed
to be calibrated for new Absolute Accuracy.
The resolver values will change when parts affecting the calibration position are replaced on
the robot, e.g. motors, wrist or part of transmission.
Contents of the revolution counter memory are lost
If the contents of the revolution counter memory are lost, the counters must be updated as
detailed in section Updating revolution counters on page 168. This will occur when:
•
the battery is discharged
•
a resolver error occurs
•
the signal between a resolver and measurement board is interrupted
•
a robot axis is moved with the control system disconnected
The revolution counters must also be updated after the robot and controller are connected at
the first installation.
The robot is rebuilt
If the robot has been rebuilt, e.g. after a crash or when the robot has been changed for other
reachability, it needs to be recalibrated for new resolver values.
If the robot has Absolute Accuracy calibration, it needs to be calibrated for new Absolute
Accuracy.

Description
Calibration method
Standard
calibration
The calibrated robot is positioned at home
position, i.e. the axes positions (angles) are
set to 0º.
Standard calibration data is found in the file
calib.cfg, supplied with the robot at delivery.
The file identifies the correct resolver/motor
position corresponding to the robot home
position.
From deliveries together with RobotWare 5.0.5
and higher, the data will instead be found on
the SMB (serial measurement board) in the
robot, and not in a separate file.

(standard method)
or
Levelmeter calibration
(alternative method)
Absolute Accuracy
calibration
(optional)
Based on standard calibration, but besides
CalibWare
positioning the robot at home position, the
Absolute Accuracy calibration also
compensates for:
• mechanical tolerances in the robot
structure
• deflection due to load.
Absolute Accuracy calibration focuses on
positioning accuracy in the Cartesian
coordinate system for the robot.
Absolute Accuracy data is found in the file
absacc.cfg, supplied with the robot at delivery.
The file replaces the calib.cfg file and identifies
motor positions as well as absacccompensation parameters.
From deliveries together with RobotWare 5.0.6
and higher, the data will instead be found on
the SMB (serial measurement board) in the
robot, and not in a separate file.
A robot calibrated with AbsAcc has a sticker
next to the identification plate of the robot.
To regain 100% Absolute Accuracy
performance, the robot must be recalibrated
for Absolute Accuracy!

5 Calibration information
5.2. Calibration methods
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.

Calibration movement directions
When calibrating, the axis must consistently be run towards the calibration position in the
same direction, in order to avoid position errors caused by backlash in gears etc. Positive
directions are shown in the figure below.
This is normally handled by the robot calibration software.
Note! The figure shows an IRB 7600, but the positive direction is the same for all robots,
except the positive direction of axis 3 for IRB 6400R which is in the opposite direction!

(RobotWare 4.0).
Storing the revolution counter setting
with the FlexPendant on page 170
(RobotWare 5.0).
Correct calibration position of axis 4 and 6
When running the robot to calibration position, it is extremely important to make sure that
axes 4 and 6 of the below mentioned robots are positioned correctly. The axes do not have
any mechanical stops and can therefore be calibrated at the wrong turn.
Make sure the axes are positioned according to the correct calibration values, not only
according to the calibration marks. The correct values are found on a label, located either on
the lower arm or underneath the flange plate on the base.
At delivery the robot is in the correct position, do NOT rotate axis 4 or 6 at power up before
the revolution counters are updated.
If one of the below mentioned axes are rotated one or more turns from its calibration position
before updating the revolution counter, the exact calibration position will be lost due to
uneven gear ratio. This affects the following robots:
