14.2 Parameter initialization function
The "parameter initialization function" is used to return the setting data set in the
QD77MS buffer memory/internal memory and flash ROM/internal memory (nonvolatile)
to their factory-set initial values.
The details shown below explain about the "parameter initialization function".

[3] Precautions during control
[4] Parameter initialization method
[1] Parameter initialization means
• Initialization is executed with a sequence program.
• Initialization is executed by GX Works2.
Refer to the "Simple Motion Module Setting Tool Help" of GX Works2 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/internal memory" and " flash
ROM/internal memory (nonvolatile)" setting data.)

Positioning data (No.1 to 600)
Block start data (No.7000 to 7004)
[3] Precautions during control
(1) Parameter initialization is only executed when the positioning control is not
carried out (when the PLC READY signal [Y0] is OFF).
A warning "In PLC READY (warning code: 111)" will occur if executed when
the PLC READY signal [Y0] is ON.
(2) A writing to the flash ROM is up to 100,000 times. If writing to the flash ROM
exceeds 100,000 times, the writing may become impossible, and "Flash
ROM write error (error code: 801)" will occur.
(3) A "PLC CPU reset" or "PLC CPU power restart" must be carried out after
the parameters are initialized.
(4) If an error occurs on the parameter set in the QD77MS when the PLC
READY signal [Y0] is turned ON, the QD77 READY signal [X0] will not be
turned ON and the control cannot be carried out.
