5.7 List of control data

The setting items of the control data are explained in this section.
• Guide to buffer memory address
In the buffer memory address, "n" in "4303+100n", etc. indicates a value
corresponding to axis No. such as the following table.
(Note-1): Calculate as follows for the buffer memory address corresponding to each axis.

5.7.1 System control data

Setting item
[Cd.1] Flash ROM write request
[Cd.2] Parameter initialization request
Axis No. n Axis No.
1 0 5
2 1 6
3 2 7
4 3 8
(Example) For axis No. 16
4303+100n ([Cd.6] Restart command) = 4303+100 15 = 5803

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] [RJ010 mode]
116 [ms] [CiA402 mode]
POINT
(1) Do not turn the power OFF or reset the PLC CPU while writing to the flash ROM.
If the power is turned OFF or the PLC CPU is reset to forcibly end the process,
the data backed up in the flash ROM will be lost.
(2) Do not write the data to the buffer memory before writing to the flash ROM is
completed.
(3) The number of writes to the flash ROM with the sequence 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: 805).
Refer to Section 16.4 "List of errors" for details.
(4) 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".

Requests initialization of setting data.
Refer to Section 14.2 for initialized setting data.
Initialization: Resetting of setting data to default values
Fetch cycle: 103 [ms] [RJ010 mode]
116 [ms] [CiA402 mode]
Note: After completing the initialization of setting data, switch the power ON or
reset the PLC CPU.
