1 inch = 40,000 counts

and the speeds of

1 in/sec = 40,000 count/sec

5 in/sec = 200,000 count/sec

an acceleration rate of 0.1g equals

0.1g = 38.6 in/s2 = 1,544,000 count/s2

Note that the circular path has a radius of 2" or 80000 counts, and the motion starts at the angle of 270

°

and traverses 360

° in the CW (negative direction). Such a path is specified with the instruction

CR

80000,270,-360

Further assume that the C must move 2" at a linear speed of 2" per second. The required motion is
performed by the following instructions:
