Logix Designer application version 
19 and earlier 
MAM instruction programmed as 
rate. 
 
Position     50.0 mm (start 
0.0) Speed  10.0 mm/sec 
Accel  40.0 mm/sec2 
Decel  40.0 mm/sec2 
 
So Travel_Distance = area under 
the curve [accel + at_speed + 
decel] Travel_Distance = 50 mm 
Travel_Distance = 50 mm [1.25 
mm + 47.5 mm + 1.25 mm 
In this figure, we are programming time. In Logix Designer application, version 
V20, the controller calculates the speed of the move: Speed & Accel/Decel as time 
[seconds].
