Figure 20-17 Sample program
M_Mxt (CPU number) is a special variable that can communicate state between CPUs. Take the timing of
starting and ending cooperative operation using this variable.
When coordinated operation is controlled from a robot program, the robot 1 executes a movement command
while the robot 2 is executing the Mxt command. If the slave side cannot keep up with over speed or outside the
operating range, it generates an error and stops.
20.4.2. Interference avoidance
It is possible to operate the robot while checking interference with other robots.
For details, refer to the instruction manual “Detailed explanations of functions and operations 5.24 Interference
avoidance function”.
Also, refer to "13.3.15 Collision avoidance parameters" for how to set the interference avoidance parameters
with this software.
