(2) Write Variable Data
(a) You write data you want by designating module internal memory address of parameter, operation data,
CAM data directly.
(b) Writes data
set in PLC program as many as “Block size” starting position set in “Write address” with
WORD unit among parameter, operation data, CAM data of positioning module.
In case “No. of block” is
higher than 2, writes blocks with interval of “OFFSET” starting “Write address” as many as “CNT”-1.
(c) Max. data size (Block size x No. of block) you can write with one command is 128 WORD.
(d)
“Read Variable Data” command can‟t be executed in operation. But changing the user cam data of
relevant axis is available about an axis in the cam control operation.
(e)
After executing “Write Variable Data” command, since the changed value is maintained while power is on,
in order to keep the changed value, execute “Save parameter/Operation data” command
(f) Auxiliary data setti
ng of “Write Variable Data” command

Description
Data device
-
Sets device where data to write to module is
saved
Write address
0 ~ 73769
Sets head address of positioning module
internal memory
Block offset
0 ~ 73769
Sets offset between blocks of Write data
Block size
1 ~ 128
Sets size of block
No. of block
1 ~ 128
Sets No. of Write block
(g) Restriction
In the following case, error occurs and can‟t execute “Read Variable Data” command
■ Data range setting error (Error code: 711)
▪ Write data size (Block size x No. of block) is 0 or higher than 128 WORD
▪ Write data address [Write a {Block offset x (No. of block -1)} + Block size] is higher than
last address value (73769)
■ Block overlap error (Error code: 713)
▪ In case module internal block to write is overlapped each other
(In case no. of block is higher than 2, block offset is smaller than block size)
■ Execution inhibition error in operation (Error code: 712)
▪ Any axis of positioning module is in operation
