8.3 Memory Initialization
The following methods can be used to delete (initialization) data on Motion CPU standard ROM, backup RAM, and SD
memory cards.
*1 Executed during STOP. Cannot be performed in installation mode.
*2 Executed with built-in memory clear (rotary switch set to "C"). Refer to the following for details.
MELSEC iQ-R Motion Controller User's Manual
*3 The following devices that are used as internal signals of the Motion CPU are not cleared by "zero clears other than Latch(1)/latch(2)".
• Backup data includes the servo parameter open area, absolute position data, current value history data,
scroll monitor information, and synchronous control backup data.
• The system operating system software is not deleted even when initializing data.
• If the backup RAM of the Motion CPU is initialized, the device assignment method becomes "Q series
Motion compatible device assignment".
• Refer to the following for details on MT Developer2 operation.
