120 Function Library
for motion completion but immediately return control to the pro-
gram.
_8168_start_ta_move
:
This function causes the axis to accelerate from a starting velocity,
slow at a constant velocity, and decelerate to a stop at the speci-
fied absolute position with trapezoidal profile. The acceleration
and deceleration time is specified independently. It won’t let the
program wait for motion completion but immediately return control
to the program.
_8168_start_sr_move
:
This function causes the axis to accelerate from a starting velocity,
slow at a constant velocity, and decelerate to a stop at the relative
distance with S-curve profile. The acceleration and deceleration
time is specified independently. It won’t let the program wait for
motion completion but immediately return control to the program.
_8168_start_sa_move
:
This function causes the axis to accelerate from a starting velocity,
slow at a constant velocity, and decelerate to a stop at the speci-
fied absolute position with S-curve profile. The acceleration and
deceleration time is specified independently. It won’t let the pro-
gram wait for motion completion but immediately return control to
the program.
_8168_set_move_ratio
:
This function configures scale factors for the specified axis. Usu-
ally, the axes only need scale factors if their mechanical resolu-
tions are different. For example, if the resolution of feedback
sensors is two times the resolution of command pulse, then ratio =
2.
_8168_p_change
This function is used to change target position on the fly. There are
some limitations for this function. Please refer to section 4.6.2
before using it.
_8168_set_pcs_logic
:
This function is used to set the logic of Position Change Signal
(pcs). The PCS share the same pin with SD signal. Only when the
