Trapezoidal Motion Mode
@ Name
_8134_start_ta_move – Begin an absolute trapezoidal profile
motion
_8134_start_tr_move – Begin a relative trapezoidal profile motion
_8134_set_rdp_mode – Set ramping down mode
@ Description
_8134_start_ta_move() :
This function causes the axis to accelerate from a starting velocity,
slew at constant velocity, and decelerate to stop at the specified
absolute position, immediately returning control to the program. The
acceleration rate is equal to the deceleration rate.
_8134_start_tr_move() :
This function causes the axis to accelerate from a starting velocity,
slew at constant velocity, and decelerate to stop at the relative
distance, immediately returning control to the program. The
acceleration rate is equal to the deceleration rate.
_8134_set_rdp_mode():
Switch the motion slow down mode for auto or manual mode. The
mode is default in manual mode.
