for the first time. If the target frequency specified by S
time is reloaded for execution. But if the target frequency is modified when the output enters the ramp-down process,
the instruction ignores the change.
6. D only allows Y0.0–Y0.11 as the pulse output devices. After the instruction is executed, its output function becomes
the high-speed output, and the general instruction output point control is invalid. It is suggested that you do not use
the general output function after using the high-speed output function in the program.

8. The ratio of Duty-OFF Time and Duty-ON Time for the pulse output is 1:1.
9. There is no limit to how many times you can use the instruction a program. But only one output instruction that uses
the same output point can be executed in the same scan cycle. When several high-speed pulse output instructions
start the same output point in the program, the PLC first performs the output based on the instruction that is executed
first.
10. After the high-speed output instruction for one output point is enabled, other instructions that occupy the same output
point can not start until the high-speed output instruction in execution is disabled.
11. When the high-speed output instruction is executed in an interrupt program or is not in the main program, it is
suggested that you use the instruction with the auto-reset function when the output is completed and the PLC updates
the output state in the END instruction.
12. After the stop flag is set, PLC performs the ramp-down stop; or it immediately stops the output only after the start
instruction is executed a second time and outputs a full pulse.
13. Refer to the PLSY instruction (API 2700) for an explanation of the high-speed output points and corresponding SM/SR.
14. Refer to Example 3 from the PLSY instruction (API 2700) for programming in ST language.
