Precautions during control
• 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: 0D05H) will occur if executed when the PLC READY signal [Y0] is ON.
• 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 the error "Flash ROM write error" (error code: 1A31H) 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 Motion module when the PLC READY signal [Y0] is turned ON, the READY
signal [X0] will not be turned ON and the control cannot be carried out.
Parameter initialization takes approximately 7 seconds. When a short time is assigned to the main cycle
initialization may take more than 7 seconds.
Do not turn the power ON/OFF or reset the CPU module 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/internal memory (nonvolatile) will be lost.
*1 Cycle of processing executed at free time except for the positioning control. It changes by status of axis start.
Parameter initialization method
• Parameter initialization can be carried out by writing the data shown in the table below to the buffer memory of Motion
module. The initialization of the parameter is executed at the time point the data is written to the buffer memory of Motion
module.
