Move and Jog Profiles
The IMC-S/23x provides three types of motion profiles for moves and
jogs on physical
SERVO
axes and the imaginary axis . These are the
TRAPEZOIDAL
(linear acceleration and deceleration),
S-CURVE
(controlled jerk), and
PARABOLIC
. Toggle to the desired selection and

.
A guide to the effects of these three motion profiles on various
application requirements is given below:
Trapezoidal
The trapezoidal velocity profile is the most commonly used profile
since it provides the most flexibility in motion programming and the
fastest acceleration and deceleration times.
