DPI
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 the
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.
