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
press ENTER.
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.
