1 POSITION AREA
The position area of the Auto Tab displays the position of each machine axis. If the number
displayed is orange, the machine is not in machine home position and must be homed before pro-
ceeding.
2 JOG AREA & SPEED AREA
The jog area has eight buttons for bi-directional jogging of each of the X,Y,Z and A axes. Clicking
the button for the desired axis and direction will cause that axis to move in the direction chosen.
ThE Speed Area directly corresponds to the Jog area. There are two radio buttons that determine
how the jog movement is made: Continuous and Incremental speed.
• CONTINUOUS & INCREMENTAL SPEED
If the Continuous radio button is selected, when the X- or X+ button is clicked the machine table
will move in the selected direction until the mouse button is released, reaches the soft limit (soft
limits are explained in appendix A of this manual.) of travel or has reached the preset position
determined by the operator. The movement is at the jog speed represented by the Jog Speed
slider.
If the Incremental radio button is selected, when the X- or X+ button is clicked the table will move
the distance entered into the amount field. Each time the mouse is clicked the table will move that
distance until the machine has either reached the soft limits of travel or the position desired by the
operator. The movement is at the jog speed represented by the Jog Speed Slider.
• AMOUNT
The amount field allows the user to key in or use the up and down arrows on the side of the amount
field to enter the desired amount the operator would like to jog a particular axis. Clicking the up
arrow will increase the numbers from 0.001” to 0.01” 0.1” to 1”. The operator can manually key in
any number between 0.001” and 1.0”. For instance, to move the X-axis in the selected direction back
to the part home (also called part zero) a 1/2” (0.5”) of an inch at a time, enter 0.5 in the amount
field. Click on the desired direction of travel button in the Jog area. Selected the radio button for
Continuous speed. The table will then move a half an inch in the selected direction each time you
click the mouse. Hold the mouse key down until the table has moved the amount denoted in the
amount field. Selecting the incremental radio button will cause the table to move in the selected
direction a 1/2-inch at a time, until it reaches the desired position. Please note: if you have selected
the incremental radio button, an amount of desired incremental movement must be selected for
each axis.
• FEED & RAPID BUTTONS
If the Feed button is selected the machine axial movement will travel at the selected jog speed
displayed in the Jog Speed field. If you click the Rapid button, the machine’s axial movement will
progress at the maximum feed rate of 120 inches per minute.
