In Figure 112, we are programming rate. The controller calculates the time of
the move: Speed and Accel/Decel as units = units (seconds).

Position 50.0 mm (start 0.0)
Speed 10.0 mm/sec
Accel 40.0 mm/sec

Decel 40.0 mm/sec

Start 0.0 End = 50.0 mm Speed = 10 mm/sec Accel/Decel = 40.0 mm/sec

Equivalent to: Distance Rate
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
