S-curve profile

_8132_fix_max_speed – Set max speed when using v_change()
function
@ Description
_8132_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.
_8132_sv_move:
This function is similar to v_stop() but accelerating with S-curve.
_8132_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. However, if you operate under
“Preset Mode” (like start_a_move(),… ), you are not allowed to
change the acceleration parameter during operation because the
deceleration point is pre-determined. But changing the acceleration
parameter when operating under “Constant Velocity Mode” is valid.
_8132_fix_max_speed:
In order to calculate better performance when using
v_change() function, user must set this function before any PTP
function
_8132_v_stop:
This function is used to decelerate an axis to stop. This function is
also useful when
preset move (both trapezoidal and S-curve motion),
