GSC GSB FCD DPI
3401
ABS MAB DPI
[Data type] Bit
DPI When a decimal point is omitted in an address that can include a
decimal point
0 : The least input increment is assumed.
1 : The unit of mm, inches, or second is assumed. (Pocket
calculator type decimal point input)
FCD When an F command and a G command (G98, G99) for feed per
minute or feed per rotation are specified in the same block, and the G
command (G98, G99) is specified after the F command, the F
command is:
0 : Assumed to be specified in the mode (G98 or G99) when the F
command is specified
1 : Assumed to be specified in the mode of the G command (G98 or
G99) of the same block
NOTE
1 When FCD = 1:
If the block containing a G command (G98, G99)
does not include an F command, the last F
command specified is assumed to be specified in
the G command mode of the block.
Example
N1 G99 ;
N2 Faaaa G98 ; - Faaaa is assumed to be
specified in the G98 mode.
N3 Fbbbb ; - Fbbbb is assumed to be
specified in the G98 mode.
N4 G99 ; - Fbbbb is assumed to be
specified in G99 mode.
2 In G code system B or C, G98 and G99 function
are specified in G94 and G95.
MAB Switching between the absolute and incremental commands in MDI
operation
0 : Performed by G90 or G91
1 : Depending on the setting of ABS, #5 of parameter No.3401
ABS Program command in MDI operation
0 : Assumed as an incremental command
1 : Assumed as an absolute command
NOTE
ABS is valid when MAB, #4 of parameter No.3401,
is set to 1.
