@ Description
_8164_tv_move:
Accelerates an axis to the specified constant velocity with a trape-
zoidal profile. The axis continues 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 the velocity parameter.
_8164_sv_move:
Accelerates an axis to the specified constant velocity with a S-
curve profile. The axis continues 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.
_8164_v_change:
Changes the moving velocity with a trapezoidal profile or S-curve
profile. Before calling this function, define the speed range by
_8164_fix_speed_range. _8164_v_change is also applicable on
pre-set motion.
