Processing details
• These instructions reset the module parameters and module extension parameters in the buffer memory of the positioning
module, and the settings in the module extension parameter file to the factory default settings (initial values).
• The setting data initialized include the parameters, positioning data (No. 1 to 600), and block start data (No. 7000 to 7004).
• Whether the GP.PINIT instruction has been completed normally or with an error can be checked with the completion device
(d) or completion status indication device (d)+1.

• For details of the function, refer to MELSEC iQ-F FX5 User's Manual (Positioning Control - Intelligent function module).
Precautions
• The GP.PINIT instruction can be executed when the READY signal ([Md.140] module status: b0) is OFF. While the READY
signal ([Md.140] module status: b0) is ON, if the GP.PINIT instruction is executed, "Writing during PLC READY ON
(Warning code: 0905H) warning occurs in the positioning module and the initializing the module cannot be executed. Turn
the "[Cd.190] PLC READY signal" OFF, and turn the READY signal ([Md.140] module status: b0) OFF before executing the
GP.PINIT instruction.
• Data write to the flash ROM of the positioning module can be repeated a maximum of one hundred thousand times. Any
attempt to write data to the flash memory beyond this count results in failure, and the flash ROM write error (error code:
1931H) occurs.
• After the power is turned on or the CPU module is reset once, module backup (including the number of times initialization is
executed) can be repeated a maximum of 25 times if the program is used. Any attempt to write data to the flash ROM
memory beyond 25 times results in a flash ROM write count error at error code 1080H. If this error occurs, reset the
positioning module error with "[Cd.5] axis error reset", by turning the power OFF to ON, or by resetting the CPU module.
• If this instruction is executed in an interrupt program with the priority 1, operation error (3580H) occurs. This instruction
operates in an interrupt program with the priority 2 or 3.

Description
This device turns on during the END processing of the scan where the GP.PINIT instruction completed, and turns
off during the next END processing.
This device turns on or off depending on the completion status of the GP.PINIT instruction.
When completed normally: Unchanged from off.
When completed with an error: Turns on during the END processing of the scan where the GP.PFWRT
instruction completed, and turns off during the next END processing.
