Siemens 840D 104119 - PA: Feed value outside range
Alarm 104119 occurs when a programmed feedrate (F-word) value exceeds the permissible range defined in the machine data parameters. This typically happens when the F-value is either too high (exceeding maximum allowable feedrate) or too low (below minimum threshold), or is improperly formatted in the NC program.

Root Cause Summary
Alarm 104119 occurs when a programmed feedrate (F-word) value exceeds the permissible range defined in the machine data parameters. This typically happens when the F-value is either too high (exceeding maximum allowable feedrate) or too low (below minimum threshold), or is improperly formatted in the NC program.
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Review the NC program line triggering the alarm and identify the programmed F-value.
- 2
Access machine data and check MD36200 $MA_MAX_AX_VELO for each axis and MD36300 $MA_AX_VELO_LIMIT to determine maximum allowable feedrate.
- 3
Check setting data SD42010 $SC_MAX_PATH_VELO and SD43200 $SC_MAX_AX_VELO for channel-specific maximum feed limits.
- 4
Modify the NC program to use a feedrate value within the permissible range, or request machine data adjustment from machine manufacturer if higher feedrate is operationally required.
Do not increase machine data feedrate limits without consulting machine tool builder documentation, as this may damage mechanics or reduce safety.
