is different from the original time. The dotted line is the ramp-up and ramp down timing diagram after the target
frequency is modified.

12. If there is any change on the frequency during ramp up or ramp down, the change can only be carried out after the
original frequency completes outputting. For example, if the new target frequency is 100 Hz and the ramp-up timing
is set at 100 (1 second), after the original frequency completes outputting, the new target frequency 100 Hz will be
outputted next. (Even though the target frequency changes every 10 ms but if the pulse does NOT complete
outputting, the change can NOT be applied.)
Example (ST program):
It is suggested to use ladder diagrams as the programming language in this instruction. If you need to use structured
texts, you need to use the output completion auto-reset flag as well for the PLC to know the output point is free and
ready to be used again when the output completes. Taking Y0.0 as the output point, the program should be written as
below. See the following example.
