System control data
Item
[Cd.1] Flash ROM write request
[Cd.2] Parameter initialization request
[Cd.41] Deceleration start flag valid
[Cd.42] Stop command processing for deceleration stop selection
[Cd.44] External input signal operation device (Axis 1 to 8)
[Cd.102] SSCNET control command
[Cd.137] Amplifier-less operation mode switching request
[Cd.190] PLC READY signal
[Cd.191] All axis servo ON signal
[Cd.1] Flash ROM write request
• Writes not only "positioning data (No.1 to 600)" and "block start data (No.7000 to 7004)" stored in the buffer memory/
internal memory area, but also "parameters" and "servo parameters" to the flash ROM/internal memory (nonvolatile).
Fetch cycle: 103 [ms]
• Do not turn the power OFF or reset the CPU module while writing to the flash ROM. 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 will be
lost.
• Do not write the data to the buffer memory before writing to the flash ROM is completed.
• The number of writes to the flash ROM with the program is 25 max. while the power is turned ON. Writing to
the flash ROM beyond 25 times will cause the error "Flash ROM write number error" (error code: 1080H).
Refer to Page 589 List of Error Codes for details.
• Monitoring is the number of writes to the flash ROM after the power is switched ON by the "[Md.19] Number
of write accesses to flash ROM".
■Setting value
• Set with a decimal.
Setting
K 1
value
The Simple Motion module resets the value to "0"
automatically when the write access completes.
(This indicates the completion of write operation.)
• Buffer memory address
Refer to the following for the buffer memory address in this area.
