13.6.3 Frequency control mode (HSZ and PLSY instructions) (M8132)
When the special auxiliary relay M8132 for declaring the frequency control mode is specified as in the DHSZ
instruction, the special function shown below is provided if DPLSY instruction is combined.
At this time, only a data register D can be specified as , and a constant K or H can be specified as . The
available range is limited to "1 ≤ K, H ≤ 128".
A high speed counter C235 to C255 can be specified as .
This function is different from the zone comparison described above.
PLSY instruction is as shown on the next page, and only the pulse output can be changed by users.
