The following illustration -
Velocity Profiles of XY
shows the velocity profiles for the X and Y axis.
Velocity Profiles of XY
Notes on Velocity Profiles of XY illustration: The X axis has a ‘trapezoidal’ velocity profile, while the Y axis has a
‘triangular’ velocity profile. The X axis accelerates to the specified speed, moves at this constant speed, and then
decelerates such that the final position agrees with the commanded position, PR. The Y axis accelerates, but before
the specified speed is achieved, must begin deceleration such that the axis will stop at the commanded position.
