@ Description
v_move:
This function is used to accelerate an axis to the specified constant
velocity. The axis will continue to travel at a constant velocity until the
velocity is changed or the axis is commanded to stop. The direction is
determined by the sign of velocity parameter.
sv_move:
This function is similar to v_stop() but the accelerating is S-curve.
v_change:
You can change the velocity profile of command pulse ouput during
operation by this function. This function changes the maximum velocity
setting during operation.
v_stop:
This function is used to decelerate an axis to stop anytime.
