NoDwell Motion,
Rise ReturnRise Motion 
The reciprocating motion repeated from starting point to stopping point without any interruption while the stroke continues to accelerate at a given rate. Used to reduce the Am. 

NonDimensional Acceleration 
Nondimensional velocity differentiated by nondimensional time. The maximum nondimensional acceleration is expressed as Am. For highspeed driving applications, select the curve with the smallest Am.  
Displacement 
The displacement of a motion from start
to stop represented between 0 to 1. S = s/yh NOTE: S is the nondimensional displacement, s is the real displacement (mm or rad), and yh is the maximum displacement (mm or rad). 


Nondimensional acceleration differentiated by nondimensional time. Used to indicate the rate of change in acceleration. The maximum nondimensional jerk is expressed as Jm.  

The time of a motion from start to stop
represented between 0 to 1. T = t/th NOTE: T is the nondimensional time, t is the real time (s), and th is the time (s) up to the maximum displacement. 

Velocity 
Nondimensional displacement differentiated by nondimensional time. The maximum nondimensional velocity is expressed as Vm. When driving heavy loads, select the curve with the smallest Vm.  

The vertical and perpendicular directions of a line at any given point on a plane or curve.  

The number of stops the output shaft makes during intermittent (indexing) rotation. The output shaft rotates 360°/s between stops where s equals the number of stops.
