8.5 Recalibrating the axes
General
This measure is necessary when the external axes lack calibration values or you
wish to recalibrate the axes.
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.
Note
This procedure should not be used if calibration values already exist for the
axis in question.
Positioners of the types A, L and MTD
Note Action
Move the positioner's axes (axis) to respective zero positions
(synchronization marking).
• Be precise when adjusting the position of the axis so
that it lies in the centre of the marking. The marking is
made up of a machined groove or a machined notch
on the gearbox respective faceplates.
