*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 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.
Pulse output destination device
While instruction is active, associated output is ON. (LED is also ON.)
Use a special high speed adapter.
Set the output frequency to "200kHz" or less.
Set the output frequency to "100kHz" or less.
