2.3 Recalibrating the axes

This measure is necessary when the external axes lack calibration values or you

wish to recalibrate the axes.

This procedure should not be used if calibration values already exist for the axis in ques-

tion.

You should be aware that the programmed positions can change depending on

whether the new calibrated position differs from the previous position.

The chapter describes the procedure for the positioner, not for the robot. (Specialist

know-how, which is not described here, and equipment are required to calibrate the

robot's axes.)

Calibration of the external axes is performed in different ways depending on the

type of positioner in question.

Action

1. Move the positioner's axes (axis) to respective zero positions (synchronization mar-

king).

• Be precise when adjusting the position of the axis so that it lies in the centre of

marking.

The marking is made up of a machined groove or a machined notch on the gearbox

respective faceplates.

2. Tap ABB, to open the service window.

3. Tap Calibration.
