Parameter Initialization Function
The "parameter initialization function" is used to return the setting data set in the LD75 buffer memory and flash ROM
to their factory-set initial values.
The details shown below explain about the "parameter initialization function".
• Parameter initialization means
• Control details
• Control precautions
• Parameter initialization method
(1) Parameter initialization means
• Initialization is executed with a program.
• Initialization is executed by GX Works2.
Refer to

GX Works2 Version 1 Operating Manual (Intelligent Function Module) for the execution method by
GX Works2.
(2) Control details
The following table shows the setting data initialized by the "parameter initialization function".
(The data initialized are "buffer memory" and " flash ROM " setting data.)
(3) Control precautions
• Parameter initialization is only executed when the positioning control is not carried out (when the PLC
READY signal [Y0] is OFF). The warning "In PLC READY (warning code: 111)" will occur if executed when
the PLC READY signal [Y0] is ON.
• Writing to the flash ROM can be executed up to 100,000 times. If writing to the flash ROM exceeds 100,000
times, the writing may become impossible, and the error "Flash ROM write error" (error code: 801) will occur.
• A "CPU module reset" or "CPU module power restart" must be carried out after the parameters are
initialized.
• If an error occurs on the parameter set in the LD75 when the PLC READY signal [Y0] is turned ON, the LD75
READY signal [X0] will not be turned ON and the control cannot be carried out.
Parameter initialization takes about 10 seconds. (Up to 30 seconds are sometimes required.)
Do not turn the power ON/OFF; reset the CPU module, etc., during parameter initialization.
If the power is turned OFF or the CPU module is reset to forcibly end the process, the data backed up in the flash ROM will
be lost.
