Number of basic steps 67 steps
The number of FB steps integrated in the program varies depending on the CPU module used, the input/output definition, and
the setting options of GX Works3. For the setting options of GX Works3, refer to GX Works3 Operating Manual.
Processing By turning on i_bEN (Execution command), the setting data stored in the buffer memory and the flash ROM of the FX5-20PG-
P is reset to the factory setting.

Restrictions or precautions • This FB does not include the error recovery processing. Program the error recovery processing separately in accordance
with the required system operation.
• This FB cannot be used in an interrupt program.
• Do not use this FB in programs that are executed only once, such as a subroutine program or FOR-NEXT loop, because
i_bEN (Execution command) cannot be turned off and the normal operation cannot be acquired. Always use this FB in
programs that can turn off i_bEN (Execution command).
• Every input must be provided with a value for proper FB operation.
• Before using this FB, check that PLC READY signal (Cd.190: PLC READY signal) is OFF.
• After the setting data is initialized, reset the CPU module or power on the programmable controller again.
• The pulse output mode and external input/output signal logic, etc. must be set according to the connected devices and
system before operating the positioning module. Set the GX Works3 module parameters according to the application. Refer
to the MELSEC iQ-F FX5 User's Manual (Positioning Control - Intelligent function module) for details on setting the
module parameters.
