In Figure 113, we are programming time. The controller calculates the speed of
the move: Speed and Accel/Decel as time [seconds].

Travel Distance @ speed = Time
RSLogix 5000 software version 20 and later
MAM instruction programmed as time.
Position 50.0 mm (start 0.0)
Speed 5.25 sec
Accel 0.25 sec
Decel 0.25 sec
Start 0.0 End = 50.0 mm Speed = 10 mm/sec Accel/Decel = 0.25 sec
Equivalent to: Distance Time
So Travel_Distance = area under the
curve [accel + at_speed + decel]
Travel_Distance = 50 mm
Travel_Time = 5.25 sec [0.25 + 4.75 + 0.25 sec]
