1. Setting the pulse width and period
Make sure that the pulse width

• Only the following outputs can be specified in
- When using special high speed output adapters
- When transistor outputs in the main unit are used: Y000, Y001, or Y002
*1. High-speed output special adapters can be connected only to FX
When using the PWM (FNC 58) instruction with a relay output type FX
output adapter is required.
*2. When specifying Y002 or Y003 on a special high speed output adapter, a second special high speed
output adapter is required.
*3. Y002 is not available in 14-point and 24-point type FX
• The pulse output is controlled by interrupt processing not affected by the sequence program (operation
cycle).
• If the command input is set to OFF, the output from
• 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.
