@ Description
_8154_tv_move
:
This function is to accelerate an axis to the specified constant
velocity with a trapezoidal profile. 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 the velocity parameter.
_8154_sv_move
:
This function is to accelerate an axis to the specified constant
velocity with a S-curve profile. 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.
_8154_emg_stop
:
This function is used to immediately stop an axis. This function
is also useful when a preset move (both trapezoidal and S-
curve motion), manual move, or home return function is per-
formed.
_8154_sd_stop
:
This function is used to decelerate an axis to stop with a trape-
zoidal or S-curve profile. This function is also useful when a
