Calibrated Reference Payload Fixture for IRB Series

A calibrated reference payload fixture for ABB IRB robots is a machined mass with known weight, centre of gravity and inertia, mounted on the tool flange to verify load data and calibration. Such fixtures are typically made from aluminium or steel with a standard ISO flange adapter and may carry marked reference features or sockets for measurement instruments. Typical uses include commissioning, acceptance testing, periodic verification, training of operators and validation of simulation models for robot cells. A machined steel or aluminium body with a defined centre of gravity lets the controller load identification routine be compared against a known value, which is a quick way to find wrong tool data before it affects path accuracy or motor loading on the robot.
