Machine data
2.2 General machine data
Description: Cycle name for replacement routine of the D function.
If a D function is programmed in a part program block, then, depending on
machine data MD10717 $MN_T_NO_FCT_CYCLE_NAME, MD10719
$MN_T_NO_FCT_CYCLE_MODE and MD10718 $MN_M_NO_FCT_CYCLE_PAR, the MD subpro-
gram defined in MD11717 $MN_D_NO_FCT_CYCLE_NAME is called.
The programmed D number can be polled in the cycle via system variable $C_D /
$C_D_PROG.
MD11717 $MN_D_NO_FCT_CYCLE_NAME is only active in Siemens mode (G290).
No more than one M/T/D function replacement can be active per part program
line.
A modal subprogram call must not be programmed in the block with the D func-
tion replacement. Furthermore, neither subprogram return nor part program end
are allowed.
In the event of a conflict alarm 14016 is output.
Description: lThis machine data is used to adapt the axis feed override switch to the
interface coding of the PLC interface.
1: The 5 low-order bits of the PLC interface signal DB380x DBX0 (Feed over-
ride A-H) are interpreted as a Gray code. The value which is read corresponds
to a switch setting. It is used as an index for selecting the correct over-
ride factor from the table of MD12010 $MN_OVR_FACTOR_AX_SPEED [n].
0: The feed override byte of the PLC interface is interpreted as a binary
representation of the override value in percent (limit 200 percent).
Related to:
NC/PLC interface signal DB380x DBX0 (Feed override A-H), (axis-specific)
MD12010 $MN_OVR_FACTOR_AX_SPEED [n]
(Evaluation of the axis feed override switch)
Description: Evaluation of the axis velocity override switch with gray-coded interface.
Not relevant with:
MD12000 $MN_OVR_AX_IS_GRAY_CODE = 0
