2.2.1. Less Options Profile Editor Mode
The Less Options Profile mode is the default mode. This mode is also accessed by
clicking Less Options when in the More Options Profile mode.
Figure 100 - Simple Index Motion Parameters
When using this mode to enter motion profile data, a trapezoidal velocity index
profile segment (see Automatic Index Type below) is the default motion profile.
This motion profile is optimized for minimal motor heating.

Parameter Description
Simple Index Motion
Parameters
(label 1 in
Figure 100 )
Move Distance Total distance for the motion profile.
Move Time Total time for the motion profile.
Dwell Time Total dwell time, if any, for the motion profile before the motion profile repeats.
Index Type
From the pull-down menu, choose one of three available index types.
Automatic
This is a 1/3 acceleration, 1/3 coast, 1/3 deceleration trapezoidal motion profile. This is
the default setting.
Triangular
This is a motion profile where ½ the time is spent accelerating and ½ is spent
decelerating.
Trapezoidal
This index type lets you use sliders to adjust the velocity and time axes of the motion
profile. As you mouse over a slider, the axis value is displayed.
Smoothness
This is used to decrease the discontinuity in the transition from a dwell to motion. From the pull-down menu, choose
one of three available smoothness options.
Automatic 0% Jerk time (Trapezoidal)
Standard 40% Jerk time (Partial S-curve)
Maximum 100% Jerk time (Full S-curve)
IMPORTANT Smoothness is used to reduce mechanical wear and tear. Due to display limitations, the More
Options Profile Editor Mode does not show infinite jerk at points of velocity discontinuity.
Using 0% jerk time may lead to premature mechanical failure.
