.
1. To set the maximum velocity, the function
HSL_M_fix_speed_range() must be used in order for the
function HSL_M_v_change() to work correctly. If
HSL_M_fix_speed_range() is not applied, MaxVel set by
HSL_M_v_move() or HSL_M_start_ta_move() automati-
cally becomes the maximum velocity, where
HSL_M_v_change() can not be exceeded.

2. During the acceleration or deceleration period, using
HSL_M_v_change() is not suggested, although it does
work in most cases, the acceleration and deceleration
time is not guaranteed.
