@ Description
_8102_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 com-
manded to stop. The direction is determined by the sign of the
velocity parameter.
_8102_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 com-
manded to stop. The direction is determined by the sign of velocity
parameter.
_8102_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 performed.
_8102_sd_stop:
This function is used to decelerate an axis to stop with a trapezoi-
dal or S-curve profile. This function is also useful when a preset
move (both trapezoidal and S-curve motion), manual move, or
home return function is performed. Note: The velocity profile is
decided by original motion profile.
_8102_get_current_speed:
This function is used to read the current pulse output rate (pulse/
sec) of a specified axis. It is applicable in any time in any operation
mode.
