ezoidal profile. The acceleration (Tacc) and deceleration (Tdec)
time is specified independently. This command does not let the
program wait for motion completion, but immediately returns
control to the program.
_8158_start_sr_move:
This function causes the axis to accelerate from a starting
velocity (StrVel), rotate at constant velocity (MaxVel), and
decelerates to stop at the relative distance with S-curve profile.
The acceleration (Tacc) and deceleration (Tdec) time is speci-
fied independently. This command does not let the program
wait for motion completion, but immediately returns control to
the program.
_8158_start_sa_move:
This function causes the axis to accelerate from a starting
velocity (StrVel), rotate at constant velocity, and decelerates to
stop at the specified absolute position with S-curve profile. The
acceleration and deceleration time is specified independently.
This command does not let the program wait for motion com-
pletion but immediately returns control to the program.
_8158_set_move_ratio:
This function configures scale factors for the specified axis.
Usually, the axes only need scale factors if their mechanical
resolutions are different. For example, if the resolution of feed-
back sensors is two times resolution of command pulse, then
the parameter “move_ratio” could be set as 2.
_8158_position_override:
This function is used to change target position on the fly. There
are some limitations on this function. Please refer to section
4.2.15 before use it.
