*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 only be
used once in a program.
Program example (when outputting pulses without any limitation)
When S is set to K0, pulses are output without any limitation.
