Programming Example 2
Use a CTBL (register comparison table) instruction to execute an interrupt process
when the target value is achieved.
Slowing and stopping are executed as interrupt tasks, allowing high-speed
processes to be executed without affecting the cycle time.
zLadder Program
Use a CTBL instruction to execute interrupt tasks when the target position is
reached.
When the PV of the high-speed counter matches target value 1 (3000), interrupt task
04 will be executed.

Set "motor run"
After motor stops, check the stop position.
Stop position is normal if the
high-speed counter (A270) is between
3500 (0DAC Hex) and 3550 (0DDE Hex).
Stop position is in error if the
high-speed counter (A270) is
greater than 3550 (0DDE Hex).
