2.5 Move axis

The axis command gives you access to various

functions on the axis motors.

Press HOME Axis X (A) button to start initialization of

the X axis.

Press HOME Axis Y (B) button to start initialization of

the Y axis.

Press HOME Conveyor (C) button to start initializa-

tion of the conveyor.

Press Motion with keyboard (D) button to control the movement of the XY axes manually using the

arrow keys on the keyboard. Use the page up / down keys to vary the movement step of the axes.

In Direct motion (E) section, enter the XY coordinates of the position to which you wish the camera to

move. Press Go to the coordinates button once you have entered the values in the boxes above.

In Direct conveyor motion (F) section, press Set conveyor width button to automatically adjust con-

All the boards in the conveyor will be auto-

sured from the origin (0,0). These coordinates will be used as XY conveyor references in MA-

CHINE PARAMETERS.

Incorrect coordinates can damage the axis.
