NOTE
• While the "DI10: sequence
control input" is ON, a
sequence program runs
a c c o r d i n g t o i t s o w n
cycle, regardless of robot
program starts and stops.
• T h e " D O 1 2 : S e q u e n c e

Creating a sequence program

2.1
Besides normal robot programs, the YRCX controller can execute high-speed processing programs
(sequence programs) in response to the robot input/output (DI, DO, MO, LO, TO, SI, SO) signals.
• This function allows to monitor the input/output signals of sensors, push button switches, solenoid
valves, etc. and move them. The sequence program starts running simultaneously the controller is
turned on.
• The sequence program can be written in the same robot language used for robot programs. (The
ladder logic are not necessary).
• Naming the program "SEQUENCE" makes the controller recognize as sequence program.
• For details regarding conditions to execute a sequence program, refer to "3 Executing a sequence
program" in this Chapter.
• General-purpose outputs are not reset by the program reset while the sequence function is running.
In the manner shown below, the reset of general-purpose output can be set while the sequence
program compile.
• Set a sequence flag value of the controller parameter at "3".
• Select "Output Reset Enable" on the sequence execution flag dialogue in the support software
"SCARA-YRCX Studio".
