Functional Description
The dual X-Y positioning system contains the X and Y positioning tables
which are actuated by the servo drive motors. When the motors receive a
signal they move the positioning system to predetermined coordinates
contained in the pattern program. Rotary encoders monitor the positioning
system location to ensure the positional accuracy. The X and Y tables mount
on the base and position the dual rotary tables.
