•
The MEM_WR subcommand writes the data in virtual
memory by specifying the initial address, the data size
and the data for writing.
•
This subcommand provides an adjustment function
equivalent to that of the ADJ command of the MECHA-
TROLINK-II compatible profile. For the operation proce-
dure, refer to the MEM_WR main command.
•
Confirm the completion of the subcommand execution
by checking that RSUBCMD = MEM_WR (= 1Eh) and
SUB_STAT.SUBCMDRDY = 1, and also checking the
setting for ADDRESS, SIZE and DATA.
In the following cases, an alarm will occur and the sub-
command will not be executed.
•
When the ADDRESS data is invalid:
SUBCMD_ALM = 9h(A.94A)
•
When the MODE/DATA_TYPE data is invalid:
SUBCMD_ALM = 9h (A.94B)
•
When the SIZE data is invalid:
SUBCMD_ALM = 9h (A.94D)
•
When the conditions for executing the adjustment oper-
ation are not satisfied: SUBCMD_ALM = Ah (A.95A)
•
While editing using SigmaWin or digital operator: SUB-
CMD_ALM = Ah (A.95A)
