X-Y Table Controller - Galil Motion Control DMC-18 2 Series User Manual

This implies that a distance of 10 inches equals 6370 counts, and a slew speed of 5 inches per second,
for example, equals 3185 count/sec.
The input signal may be applied to input 1, for example, and the output signal is chosen as output 1.
The motor velocity profile and the related input and output signals are shown in Fig. 7.1.
The program starts at a state that we define as #A. Here the controller waits for the input pulse on I1.
As soon as the pulse is given, the controller starts the forward motion.
Upon completion of the forward move, the controller outputs a pulse for 20 ms and then waits an
additional 80 ms before returning to #A for a new cycle.

X-Y Table Controller

An X-Y-Z system must cut the pattern shown in Fig. 7.2. The X-Y table moves the plate while the Z-
axis raises and lowers the cutting tool.
