5. Others
1) Types of pulse output, positioning and other relevant instructions and their target output numbers
*1. Y002 (pulse output destination) cannot be specified when the 14-point or 24-point type FX
3G PLC is
connected.
*2. The pulse output destination Y003 can be specified only when two special high speed output adapters are
connected to an FX
3U PLC.
*3. This function is supported only in FX
3U/FX3UC PLCs.
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 or 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 or
positioning instruction for the same output relay cannot be executed.
Before executing a pulse output or positioning instruction, wait until the pulse output monitor flag turns OFF and
one or more operation cycles pass.
