Acc/Deceleration Profile
Basic motion command usually contains distance, velocity, and
acceleration data. This controller plans and calculates Acceleration &
Deceleration profile based on these motion command parameters to
make motion operation completed as desired by users. This
controller provides following acceleration profiles:
1. Trapezoidal speed profile, T-curve
2. S-curve
4.2.3.1
Trapezoidal Speed Profile, T-curve
Trapezoidal speed profile (the so called T-curve) is a curve
where the acceleration zone and deceleration zone matches
first-order linear speed profile (equivalent acceleration). As shown
in the velocity-time chart (V-T):
