When To Calibrate - ABB IRB 6650S Series Product Manual

5.1.3 When to calibrate

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
methods supplied by ABB. Calibrate the robot carefully with standard calibration,
according to information in this manual.
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.
