!3 : Save Command
Write-only: used to save the configuration and product code in non-volatile memory.
HEX Value Description
>0000
Reset Command. Acknowledges (clears) any previous save error.
>0001
Saves Configuration to drive’s non-volatile memory.
>0100
Saves Product Code to drive’s non-volatile memory.
!4 : Save State
Read only: used to determine the progress of a non-volatile saving operation.
HEX Value Description
>0000 Idle
>0001 Saving
>0002 Failed
3. Tag Access
Each parameter in the drive’s menu system is identified by a unique Tag Number. Information
is exchanged across the system by use of a two character Mnemonic that is derived from the Tag
Number.
Note:
Refer to the Parameter Specification Table in the 650 or 650V Software Product Manual
for a full list of tag mnemonics - see the ID column. Refer to the Notes column which
gives access information about each parameter.
Parameter Mapping
650V Algorithm
The algorithm to convert between tag number and 2 character mnemonics is:
if (TagNo < 1296)
{
m = INT (TagNo / 36)
(INT: the integer part
)
n = TagNo MOD 36
(MOD: the remainder)
if m > 9 then
char_1 = ‘a’ + (m - 10)
else
char_1 = ‘0’ + m
end_if
if n > 9 then
char_2 = ‘a’ + (n - 10)
else
char_2 = ‘0’ + n
}
else
{
m = INT (TagNo - 1296) / 126)
n = (TagNo - 1296) MOD 26
char_1 = 'a' + n
char_2 = 'A' + m
}
end_if
The algorithm generates mnemonics containing only the characters ‘0’ to ‘9’ and
‘a’ to ‘z’.
