How to reduce the S to the actual step motor control!
The pulse equivalent can be calculated according to the above information when the stepping motor is controlled periodically. I tested it on the servo drive (and it can be dynamically planned, which means that the target speed can change in real time), which works.
The acceleration of the S + deceleration is a trapezoid, and the area of the trapezoid is the difference between the initial velocity (acceleration zero) and the target velocity (acceleration zero). S-shaped so to planning goal and deceleration must first know the starting speed difference (area), and know the most acceleration duration (that is, the top of the ladder duration) and S curve part time duration (namely the trapezoidal left, right), thus the shape of a trapezoid is fixed, can be calculated by calculation and acceleration (jerk).
In addition, you can refer to the instructions of the panasonic A5 servo drive specification for the speed S curve setting parameters, which will help you understand the above. Hope to help you.
