6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.12.1 NC setting data (NC SD)
Spindle-specific setting data
401*
Default value
0
The spindle speed is limited at constant cutting speed (G96) by the programmed spindle
speed limitation. The setting data can be modified in the program using the command G92.
Units
The unit of the input values is defined by MD 520*, bit 3:
Bit 3 = 0:
Bit 3 = 1:
Note
The maximum spindle speed value is determined by the minimum of the following values:
• MD 403* to 410*
• MD 451*
• SD 401*
• SD 403*
402*
Default value
0
This setting data specifies the angle to which the spindle is positioned when M19 is
programmed in the part program (or MDA, Overstore) without specifying an S value.
If an S value is programmed with M19, it is transferred to the setting data.
Examples
• The spindle is positioned to 270 degrees with
setting data.
• is used to position the spindle to the value and entered in the setting data.
M19 LF
403*
Default value
100
The maximum spindle speed is limited to this value. The setting data can be modified in the
program using the command G26.
