8.1 Memory and Files
8 MOTION CPU MEMORY STRUCTURE
Programs and parameters used for Motion CPU control are stored as files in a nonvolatile memory "standard ROM" built in to
the Motion CPU, or a "SD memory card" installed in the SD memory card slot of the Motion CPU.
The SD memory card can be removed from the Motion CPU and used with peripheral equipment such as personal
computers, facilitating flexible data management.
Furthermore, by saving the system operating system software in a predetermined folder beforehand, it can be installed in the
Motion CPU.
8.1 Memory and Files
Standard ROM/SD memory card specifications
The Motion CPU standard ROM and SD memory card specifications are as follows.
*1 Total capacity including file management area. The capacity excluding the file management area is smaller. Free memory space can be
checked with MT Developer2.
*2 Formatting is completed prior to shipping.
*3 Format SD memory cards with MT Developer2. If formatted with the Windows formatting function or with a device other than a Motion
CPU module (PLC, etc.), it will not be possible to use SD memory cards by inserting them into the Motion CPU module.
Available operations
The following operations can be performed for standard ROM and SD memory cards.
*1 Refer to memory initialization for details. (Page 352 Memory Initialization)
• SD memory cards cannot be used if write protected.
• Read-only files cannot be written to or deleted.
• The file update date and creation date is based on the No.1 PLC CPU clock data.
