Constant Velocity Motion. ADLINK Technology PCI-8136M

4.9 Constant Velocity Motion

This mode is used to operate one axis motor at constant velocity motion. The output pulse accelerates from a starting velocity (str_vel) to the specified constant velocity (max_vel). The _8136_v_move() function is used to accelerate constantly while the _8136_sv_move() function is to accelerate according to S-curve (constant jerk). The pulse output rate will keep at maximum velocity until stop function is issued. The _8136_motion_stop() function is used to stop the velocity to zero (stop). The following graph is the trapezoidal velocity profile for v_move() function. max_vel str_vel
