Execution Data Backup Function

When the buffer memory data of Simple Motion module is rewritten from the CPU module, "the data backed up in the flash
ROM/internal memory (nonvolatile)" of Simple Motion module may differ from "the execution data being used for control
(buffer memory data)". In this case, the execution data will be lost when the power supply of CPU module is turned OFF.
The "execution data backup function" is used to back up the execution data by writing to the flash ROM/internal memory
(nonvolatile). The data backed up will be written to the buffer memory when the power is turned ON next time.
When the Simple Motion module is replaced, all the data in the Simple Motion module including absolute
position data can be backed up (read to) in the personal computer and restored to (written to) the Simple
Motion module again by using the backup/restore function of an engineering tool. Refer to the "Simple Motion
Module Setting Function Help" for details.
Execution data backup means
• The backup is executed with a program.
• The data is written to the flash ROM by an engineering tool.
Refer to the "Simple Motion Module Setting Function Help" for the flash ROM write method by an engineering tool.
Control details
The following shows the data that can be written to the flash ROM/internal memory (nonvolatile) using the "execution data
backup function".
Target area
Parameters
Servo parameters
Mark detection
Synchronous control parameters
Positioning data
Block start data
• The module parameters are stored in the CPU module. Therefore, these parameters cannot be backed up in the flash ROM
in the Simple Motion module.
• The cam data (cam storage area) is separately saved in the flash ROM/internal memory (nonvolatile). Therefore, it is not a
target of the backup function.
