540 Rockwell Automation Publication MOTION-RM002H-EN-P-February 2018
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].
