46 • Operation Theorem

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.

Relative Functions:

_8136_v_move( ), _8136_motion_stop( ), _8132_sv_move(): Refer
