*1. Y002 (pulse output destination) cannot be specified when the 14-point or 24-point type FX
connected.
*2. The pulse output destination Y003 can be specified only when two special high speed output adapters
are connected to an FX
*3. This function is supported only in FX
2) When using the same output relay (Y000 or Y001) in several instructions.
While a pulse output monitor (BUSY/READY) flag is ON a pulse output instruction and positioning
instruction for the same output relay cannot be executed.
While a pulse output monitor flag is ON even after the instruction drive contact is set to OFF, a pulse
output instruction or positioning instruction for the same output relay cannot be executed.
Before executing such an instruction, wait until the pulse output monitor flag turns OFF and one or more
operation cycles pass.

3) "Frequency control mode" in which DHSZ (FNC 55) and PLSY (FNC 57) instructions are combined can
be used only once in a program.
Program example (when outputting pulses without any limitation)
When is set to K0, pulses are output without any limitation.
