5 Calibration information
5.1. Introduction
General
This chapter includes general information about different calibration methods and also details
procedures that do 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 160
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, for example motors, or parts 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 164
. 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 is rebuilt, for example after a crash or when the robot is changed for other
reachability, it needs to be recalibrated for new resolver values.
If the robot has Abslolute Accuracy calibration, it needs to be calibrated for new Absolute
Accuracy.
