5 Calibration

5.1 Introduction

General
This chapter includes information about the calibration method.
When the robot system must be recalibrated, it is done with special calibration
tools and according to this section.

When to calibrate

The system must be calibrated if any of the following situations occur.

The resolver values are changed

If resolver values are changed, the robot must be recalibrated using the calibration
method described in section
If the robot has absolute accuracy calibration, it is also recommended, but not
always necessary to calibrate 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 the transmission.

The revolution counter memory is lost

If the revolution counter memory is lost, the counters must be updated. See
Updating revolution counters on page
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 reach ability of a robot
is changed, 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.
