Operation with Digital I/O
Resetting Program Table Operation
In this example, program operation is reset during repeated operation of program steps 0 and 1
and then the program step is specified and operation is restarted from the canceled state.
Note: “Canceled” is the state in which the mode is mode 0, execution is not in a stopped state, and no program
step has been executed.
Step 0 performs relative positioning for 100,000 reference units at a speed of 15,000,000 refer-
ences units/min. The acceleration rate is 400,000,000 reference units/min/ms and the deceler-
ation rate is 200,000,000 reference units/min/ms.
Step 1 performs relative positioning for 100,000 reference units at a speed of 30,000,000 refer-
ences units/min. The acceleration rate is 400,000,000 reference units/min/ms and the deceler-
ation rate is 200,000,000 reference units/min/ms.
The program table for this positioning is shown below.
• Operating Procedure
Turn ON the /MODE 0/1 signal to change to mode 0.
Set the /SEL0 to /SEL4 signals to 0 to specify program step 0.
Turn ON the /START-STOP signal to start program table operation.
Turn OFF the /START-STOP signal to stop program table operation.
Turn ON the /PGMRES signal to cancel program table operation.
Set the /SEL0 to /SEL4 signals to 1 (i.e., turn ON /SEL0) to specify program step 1.
Turn ON the /START-STOP signal to start program table operation.
When positioning is completed to the target position, the /COIN signal turns ON.
• Operation Pattern and Related Signal Timing
* Do not change /SEL0 to /SEL7 for 4 ms after turning ON the /START-STOP signal.
