Important
Parameter initialization takes about 10 seconds. (Up to 30 seconds are sometimes
required.)
Do not turn the power ON/OFF or reset the PLC CPU during parameter
initialization. If the power is turned OFF or the PLC CPU module is reset to forcibly
end the process, the data backed up in the flash ROM/internal memory
(nonvolatile) will be lost.
[4] Parameter initialization method
(1) Parameter initialization is carried out using the dedicated instruction
"ZP.PINIT".
(Refer to Chapter 15 "Dedicated Instructions" for details.)
(2) Parameter initialization can also be carried out by the writing of the data
shown in the table below to the buffer memory of Simple Motion module
using the TO command/intelligent function device.
The initialization of the parameter is executed at the time point the data is
written to the buffer memory of Simple Motion module.
