_8154_stop_move_all
– Simultaneously stop Multi-axis motion
@ Description
Theses functions are related to simultaneous operations of multi-
axes, even in different cards. The simultaneous multi-axis opera-
tion means to start or stop moving specified axes at the same
time. The axes moved are specified by the parameter “AxisArray,”
and the number of axes are defined by parameter “TotalAxes” in
_8154_set_tr_move_all
().
When properly setup with
_8154_set_xx_move_all
(), the func-
tion
_8154_start_move_all
() will cause all specified axes to
begin a trapezoidal relative movement, and
_8154_stop_move_all
() will stop them. Both functions guaran-
tee that motion Starting/Stopping on all specified axes are at the
same time. Note that it is necessary to make connections accord-
ing to Section 1.7 on page 10 if these two functions are needed.
The following code demos how to utilize these functions. This
code moves axis 0 and axis 1 to distance 80000.0 and 120000.0
respectively. If we choose velocities and accelerations that are
proportional to the ratio of distances, then the axes will arrive at
their endpoints at the same time.
Example:
I16 axes[2] = {0, 1};
F64 dist[2] = {80000.0, 120000.0},
F64 str_vel[2] = {0.0, 0.0},
F64 max_vel[2] = {4000.0, 6000.0},
F64 Tacc[2] = {0.1, 0.6},
F64 Tdec[2] = {0.1, 0.6};
_8154_set_tr_move_all(2, axes, dist, str_vel,
max_vel, Tacc, Tdec);
_8154_start_move_all(axes[0]);
