Rotation axes

FIG. 3-2 - Accuracy Motion (Rotation axes)

The

Accuracy Motion

rotation axes are:

Alpha (1) corresponds to movement from top (0°) to bottom (90°).

The position in the illustration corresponds to 0°.

Beta (2) corresponds to the rotation movement (360°), the positive direction is

counterclockwise.

The position in the illustration corresponds to 0°.

Measuring positions

The

Accuracy Motion

has 6 standard pre-registered positions which are the most commonly

used positions, but the sequences also allow measurement at all intermediate positions.

FIG. 3-3 - Accuracy Motion (Measuring positions)

DU (Dial up)

DD (Dial down)

CD (Crown down)
