Velocity-Based Straight-Line Moves
Some motion applications require moves that travel in a straight line for a
specific amount of time at a given speed. This type of move is known as
velocity profiling or jogging.
You can use a motion control application to move a motor at a given speed
for a specific time, and then change the speed without stopping the axis.
The sign of the loaded velocity specifies the direction of motion. Positive
velocity implies forward motion and negative velocity implies reverse
motion.
Tip You can change the move constraints during a velocity move.
