6 NC Machine Data (NC MD), NC Setting Data (NC SD) 07.97
6.12.1 NC setting data (NC SD)
Spindle-specific setting data
Programmable spindle speed limitation for G96
401*
Default value Lower input limit Upper input limit Units
0 0 99 999 0.1 rev/min
Active on
–
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: Unit rev/min
Bit 3 = 1: Unit 0.1 rev/min
Note
The maximum spindle speed value is determined by the minimum of the following values:
• MD 403* to 410* ” Maximum speed” per gear ratio
• MD 451* ” Maximum chuck speed”
• SD 401* ” Programmable spindle speed limitation with G96”;
programmed with G92
• SD 403* ”Programmable spindle speed limitation”;
programmed with G26
Spindle position with M19
402*
Default value Lower input limit Upper input limit Units
0 0 35 999 0.01°
Active on
–
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
M19 S270 LF
. The angle is entered in the
setting data.
•
M19 LF
is used to position the spindle to the value and entered in the setting data.
Programmable spindle speed limitation
403*
Default value Lower input limit Upper input limit Units
100 0 99 999 0.1 rev/min
Active on
–
The maximum spindle speed is limited to this value. The setting data can be modified in the
program using the command G26.
