Galil DMC-2X00 - Manual (Page 176)

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:
